Abstract

This study aims to determine the effect of adding Polyvinyl Alcohol (PVA) to the size of silver nanoparticle synthesized using bioreductor soursop leaf extract (Annona muricata L.). Silver nanoparticle made through method bioreduction, bioreductor solution was mixed with AgNO3 precursor, without addition of PVA and with the addition of PVA. That the variant of concentrations is 1%; 1.5%; 2%; and 2.5%. Based on the analysis of functional groups of soursop leaf extract using a spectrophotometer FT-IR (Fourier Transform Infrared), showed absorption at wave number 3443 cm-1 which indicate a -OH group.The process of formation of silver nanoparticles seen by UV-Vis absorption.

Abstract

This study aims to determine the metal oxide content of natural zeolite before being activated and after being activated. The activator used was hydrochloric acid6 M. Analysis of metal oxide content was carried out using the X-Ray Fluoresence (XRF) instrument. The results showed that there was a decrease in impurity levels after the zeolite was activated by acid. The content of Al2O3; SiO2; K2O and CaObefore activation were 2.15%; 86.34%; 4.32%; and 2.54% respectively, while after activation were 2.11%; 86.40%; 4.56%; and 2.78%respectively. The content of other metal oxides (impurity) generally decreases in levels after the zeolite is activated.

Abstract

This study aims to determine the characteristics of nanochitosansynthesized from chitosan from tiger prawn shells (Panaeus monodon) using sonochemical and ionic gelation methods based on variations in chitosan concentration. The characterization of nanochitosan includedthe degree of distillation using FTIR, particle size using PSA, and morphology testing using SEM. The results showed that the chitosan obtained had a degree of deacylation of 81.23%. The average size of the smallest nanochitosan synthesized using the sonochemical method is 54.44 nm with 0.2% chitosan concentration, while that produced using the ionic gelation method is 39.65 nm with 0.05% chitosan concentration, and there is a pore appearance on the surface. nanochitosan surface. Based on these data, it can be concluded that the ionic gelation method produces a smaller average nanochitosan particle size than the sonochemical method.

Abstract

The study aimed to investigate the microstructure of natural clay from Pattallassang District, Takalar Regency, South Sulawesi Province. The clay was characterized using X-ray diffractometer (XRD), surface area analyzer (SAA), and scanning electron microscope (SEM). The XRD analysis showed that the main mineral composition of the clay was kaolinite, quartz, hematite, geothite, magnetite, and anatase phases. The SAA using BET analysis shows the large surface area of 59.26 m2/g and BJH analysis for pore distribution of 32.77 nm. SEM observations revealed that the clay consists of plate-like kaolinite particles arranged randomly. The results indicate that the natural clay from Pattallassang District has good potential for use in various industrial applications due to its high kaolinite content and favorable microstructure.

Abstract

This work investigated the use of acid treatment on the characteristics of zeolite mineral. The effects of treating zeolite with various acid solutions hydrochloric acid (HCl) and sulfuric acid (H2SO4) were measured using x-ray fluorescence (XRF), x-ray diffraction (XRD), and scanning electron microscope (SEM). The results showed an increase in the percentage of SiO2 and Al2O3 after zeolite activation, and also a decrease in the amount of impurities. The crystalline phase of the zeolite was carried out using XRD analysis, indicating the type of zeolite used is modernite. The SiO2 phase in the sample is quartz, and the Al2O3 phase is corundum. The average crystal size decreased after activation, from 14.23 nm to 6.85 nm for HCl and 5.42 nm for H2SO4. Furthermore, the surface morphology of all zeolite samples has a form of irregular spherical surface, and the surface size of the particles after activation shows a smaller particle shape. The results of this study are expected to become recommendations for further research related to natural zeolite pretreatment as a catalyst support.

Abstract

The purpose of this study was to determine the adsorption kinetic model of Cd(II) from aqueous solution using Surfactant Modified Activated Carbon-Sodium Lauryl Sulphate (SMAC-SLS). This study began by varying pH, contact time, and adsorbate concentration. The concentration of Cd(II) was measured using a spectrophotometric method. The results of the analysis showed that the optimum pH occurred at pH 5 with an adsorption percentage of 84.58±1.44% and the optimum contact time at 100 minutes with an adsorption percentage of 88.75±1.5%. Furthermore, in the variation of adsorbate concentration, the adsorption percentage decreased with increasing adsorbate concentration. The adsorption kinetics followed a pseudo second order with an R2 value of 0.9945 with an adsorption capacity of 8.89 mg/g. Thus, the use of SMAC-SLS as a future adsorbent for Cd(II) is highly recommended.
