Abstract

Ligand selectivity of tartrate vs nicotinamide in a water-methanol system has been observed in the crystallization of Mn(II) and Cd(II) complexes. These complexes were crystallized at room temperature by a layered solution technique using a water-methanol mixture solvent in a M(II):tartrate:nicotinamide (M = Mn, Cd) molar ratio of 1:1:2. Complexes of M(II)-nicotinamide and M(II)-tartrate were also prepared for data comparison. Analysis of the crystals by infrared spectroscopy, powder-X-ray diffraction and qualitative anion test showed that in a presence of both tartrate and nicotinamide, the Mn(II) forms neutral Mn(II)-tartrate hydrate complex, whereas the Cd(II) forms ionic Cd(II)-nicotinamide chloride complex. In the case of Mn(II) complex, tartrate tend to coordinate as ligand than the nicotinamide, although molar ratio of nicotinamide was doubled than that of tartrate ligand. In contrast, the neutral nicotinamide ligand is more predominant to coordinate in the Cd(II) complex than the anionic tartrate. The tartrate-nicotinamide ligand selectivity in the crystallization of Mn(II) and Cd(II) complexes is likely due to the use of tartrate salt as precursor and the choice of solvent mixture. In addition, powder-XRD analysis confirms that there was no indication of M(II)-tartrate and M(II)-nicotinamide that co-crystallized together at the same time by both metal ions.

Abstract

This research aims to incorporate pyrazine in the synthesis of Ni(II)-tartrate-pyrazine metal-organic frameworks or Ni(II)-T-P MOF as candidates of porous material. Synthesis of the targeted MOF was conducted at room temperature in a methanolic solution by mixing Ni(II) solution, L-tartaric acid (T), and pyrazine (P) solutions sequentially in various molar ratios (Ni(II):T:P = 1:1:0; 1:0:2; 1:2:2; and 1:2:4) using two different Ni(II) salts (chloride and nitrate). Solid products were characterized by infrared spectroscopy, qualitative anion identification test, melting point test, and scanning electron microscopy. The result shows that type of nickel salt affects the precipitation of Ni(II) complex, in which pale blue solids were precipitated out only from the chloride reactions (1:0:2, 1:2:2, and 1:2:4). IR and SEM analyses from the 1:2:2 and 1:2:4 reactions show the identical result as also shown by the 1:0:2 reaction, whereas qualitative anion identification test result suggests that the chloride is uncoordinated to the Ni(II). The targeted Ni(II)-T-P is unsuccessfully obtained, instead, the product is proposed to be [Ni(pyrazine)x(H2O)(6-x)]Cl2. although the tartaric acid was doubled and firstly reacted with the Ni(II), the pyrazine still has a higher preference to coordinate to the Ni(II) center than the tartrate ligand.

Abstract

Microplastics have been found in the marine environment worldwide. Due to their very small size, it could be ingested by marine organisms from small size plankton to big size fish. The aim of this study is to assess the variability of microplastics in three different organs (gills, gastrointestinal tracts, and muscles) of commercial fishes in five different fishing ports in East Java Province, Indonesia. A total of 137 fish samples from 14 species were extracted to identify the types of microplastics. The microplastics found in the fish samples were mostly dominated by fiber, fragments, and a little quantity of film. In most species, the gills accumulated more microplastics compared to the gastrointestinal tracts and muscles. Gill is the organ that is highly exposed to the environmental conditions, therefore, it is more susceptible to the microplastic contamination. The results showed that there was an inverse relationship between the size of the fish and the occurrence of microplastics (P<0.05). Small size Sardinella lemuru contained more microplastics than bigger size fish such as Katsuwonus pelamis. The variability of microplastics found in this study showed important factors such as habitat, fish size, feeding behavior, and organ function which influenced the ingestion process of microplastic. This study also revealed the presence of microplastics were not only in the gills and gastrointestinal tracts of fish, but also in its muscles. Since this study targeted commercial fishes, further research is needed to know the possible impact on human consumption of fish containing microplastics.

Abstract

This study discusses the activation of natural zeolite from Blitar City – East Java using NaOH solution (0.5 M and 1.0 M). Characteristics of unactivated and activated zeolites were also investigated, as well as the effect of the activator (NaOH solution) on functional groups, element composition, pore size, specific surface area, and total pore volume. FTIR spectroscopy, XRF, and gas physisorption were conducted to support the study. Experimental data showed that: (1) the major functional groups were observed at 1250-780 cm-1 in the infrared spectra, in which the unactivated and the activated zeolite were not significantly different; (2) the elemental composition of zeolite (Si and Al) tended to decrease after the activation process; (3) the pore size of the activated zeolite increased while the surface area and total pore volume decreased. Based on this study, activated zeolite (AZB-1.0) showed the optimum result: the pore size increased by 4.12847 nm, and the total pore volume did not decrease significantly by 0.04987 cc/g.

Abstract

Renewable dimethyl ether (DME) gas is expected to replace LPG due to the high demand for domestic fuel gas and the shortage of LPG supply. DME properties are closely identical to that of LPG. DME gas can be produced directly and indirectly from various sources, including coal, natural gas, and other readily available biomass. The synthetic DME gas produces by-product gases, mainly CO2. Thus, purification of DME is needed. Al-MOF is proposed to be one of many candidates for CO2 gas absorption. A literature review was conducted in this study to screen some potential Al-MOF based on scientific peer-reviewed articles published in the last decade. The data were gathered by developing research questions using PICO(S) analysis. Particularly, this study highlights the effect of ligands on pore sizes, the effect of the amine group on absorption capacity, and the thermal stability of Al-MOF. This preliminary study finds several potential Al-MOFs suitable for the task. Based on this study, the NH2-MIL-53(Al) and NH2-MIL-101(Al) are highlighted as having the potency to be used in the DME purification process. However, further studies, including evidence-based gas separation experiments, are compulsory and need to be performed before this Al-MOF is applied to the DME purification process on a bigger scale.

Abstract

This paper report the synthesis and characterization of fluorite single crystal prepared from gypsum waste of phosphoric acid production in silica gel. Instead of its high calcium, gypsum was used to recycle the waste which was massively produces in the phosphoric acid production. The gypsum waste, the raw material of CaCl2 supernatant, was dissolved in concentrated HCl and then precipitated as calcium oxalate (CaC2O4) by addition of ammonium oxalate. The CaCl2 was obtained by dissolving the CaC2O4 with HCl 3M. The crystals were grown at room temperature in silica gel and characterized by AAS, FTIR and powder XRD. The optimum crystal growth condition, which is pH of gel, CaCl2 concentration and growth time, were investigated. The result shows that at optimum condition of pH 5.80, CaCl2 concentrations of 1.2 M, and growth time of 144 hours, colorless crystals with the longest size of 3 mm, were obtained (72.57%). Characterization of the synthesized crystal by AAS indicates that the obtained crystal has high purity. Meanwhile, analysis by FTIR spectra shows a Ca–F peak at 775 cm-1, and powder-XRD analysis confirms that the obtained crystal was fluorite (CaF2). © 2012 by Authors, Published by BCREC Group.

Abstract

Crystal growth of cobalt (II) oxalate in silica gel at room temperature as precursor of Co3O4 nano particles has been studied. Specifically, this project is focusing on the use of two different reaction tube types toward crystallization of cobalt (II) oxalate in gel. The gel was prepared at pH 5 by reacting sodium metasilicate solution with dilute nitric acid (for U-tube) and oxalic acid (for straight tube), with gelling time of 4 days and crystal growth time of 8 (for straight tube) and 12 (for U-tube) weeks. Result shows that pink crystalline powder was directly formed using straight tube method. The use of different solvents in straight tube method affects crystallization and could delay direct precipitation of the product. In contrast, bigger and better shape of red block crystal was yielded from U-tube method; however, longer growth time was needed. FTIR studies suggest that both growth method produces identical compound of hydrated cobalt (II) oxalate. © 2013 by Authors, Published by BCREC Group.

Abstract

Cobalt(II)-tartrate hydrate coordination polymer is successfully crystallisedfrom aqueous solution at room temperature. Unlike previous methods, diammonium tartrate was used and reacted directly with an aqueous solution of cobalt(II). Single crystal X-ray and ATR-IR analyses were performed toward the synthesized crystal. The crystal structure displaysa (6,3) 2D sheet which then grow into a 3D hydrogen-bonded network. Tetra- and hexa-dentate dianionic tartaric ligands are observed in the crystal structure, in which the hexadentate ligand connects four different cobalt centres. This method is considered feasible, affordable, and simple for the production of functional polymeric cobalt(II)-tartrate hydrate.

Abstract

Calcium Sulfate Hemihydrate (CSH) with uniform morphology and high crystallinity were successfully prepared by a precipitation-hydrolysis method in a concentrated sulfuric acid solution containing fishbone-derived carbon. The CSH was produced by carbonization of fishbone powder at 500 °C for 2 h, followed by sulfonation with concentrated sulfuric acid for 3 h. The solid mixture was washed until the pH of 2, then left at room temperature for 3 days. Physical properties of synthesized CSH were characterized using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), wavelength dispersive X-ray fluorescence (WDXRF), Scanning Electron Microscope (SEM), nitrogen adsorption-desorption isotherm, and melting point test. It is concluded that the CSH were formed due to hydrolysis of fishbone-derived carbon in a moderately concentrated sulfuric acid solution of carbon-derived fishbone and crystallization into a fibrous octa calcium phosphate (OCP) form. In this research, effect of crystal growth time, effect of pH during the crystal growth, and effect of volume of the solution were also investigated.
