Abstract

Biosorption is an alternative technique which can be used in solving environmental  pollution coming from waste containing heavy metals. Biosorption  of Cr(VI) ion using biomass of seagrass,  Thalassia hemprichii at various contact time, pH and concentration has been investigated. Biosorption was performed by a batch method and  concentration  of  ions  before  and  after  biosorption  were  measured  by  atomic absorption spectrophotometer  (AAS). The equilibrium was achieved after 80 minutes. Adsorption  effectivity  of  Cr(VI)  Enhalus  acoroides  ion  was  pH  2.  Biosorption  of Cr(VI) ion by using biomass of Enhalus acoroides followed Langmuir isotherm and the result showed that biosorption capacity (Qo) of Cr(VI) ion was 8.13 mg/g.Keywords:  biosorption, Cr(VI), seagrass, Enhalus acoroides, Langmuir isotherm.

Abstract

A study on the use of MCM-48-nCaO as a catalyst in the esterification reaction of nyamplung seed oil (Calophyllum inophyllum L.) has been carried out. The characterization results of XRF, XRD and FTIR showed the success in the synthesis of heterogeneous catalysts, MCM-48- nCaO, using a grinding-impregnation method. Through esterification reaction using the catalysts, FFA content in the seed oil of nyamplung reduced from 28 to 1.7%.

Abstract

Chitosan was modified into nanoparticle chitosan in order to increase its absorptivity and solubility in water so that it can be applied in various fields. The objective of this research was to produce nanometer-sized chitosan, to characterizethe functional groups and the particle size of chitosan  as  well  as  to  test  its  antimicrobial  activity.  Chitosan  nanoparticles  were  synthesized through ionic gelation method by reacting chitosan with tripolyphosphate ions through ionic cross- linking reaction. The functional groups of chitosan were determined from its FTIR spectrum, the particle size was obtained from its X-ray diffractogram  and particle size analysis (PSA). Chitosan nanoparticles  with  the  smallest  size  based  on  XRD wereobtained  at  a  concentration  of  0.1% chitosan (CNPs 1) and chitosan 0.2% (CNPs 2) with the addition of 0.1 % tripolyphosphate ion. The sizes of chitosan nanoparticles,CNPs 1 and CNPs 2,obtained from the analysis of PSA were 224.68 and 204.32 nm, respectively. Polydisperse index value (pdi) of chitosan nanoparticles produced  were  0.226  and  0.261  (pdi  <0.5),  respectively.  The  results  indicate  that  chitosannanoparticles synthesized havehomogeneous particle size distributions. The test results against four types of pathogens showed that CNPs 2 had inhibitory activity against the three types of microbes, Staphylococcus aureus, Pseudomonas aeruginosa, and Malassezia furfur, but it was not active against the fungus of Candida albicans.

Abstract

Abstract. Dragon fruit peel is a material that is abundant and cheap. The material has been used as an adsorbent in the biosorption process for the removal of metal ions of Cd(II) from wastewater. Biosorption of Cd(II) ion by dragon fruit peel was done on the variation of contact time, pH and concentration. The concentration of metal ions Cd(II) before and after adsorption was determined using Atomic Absorption Spectrophotometer (AAS). Results showed that the optimum time was 20 minutes and the optimum pH was 5. Adsorption capacity was studied by both isotherm adsorptions of Langmuir and Freundlich. Results showed that the biosorption of Cd(II) ion using dragon fruit peel full filled the isotherm Langmuir model with the biosorption capacity (Qo) of 36,50 mg/g. The functional group involved in metal ion biosorption of Cd(II) by the peel of dragon fruit is a hydroxyl group (-OH).

Abstract

Nickel is one of the heavy metals which is very dangerous because it is carcinogenic and can cause a variety of acute and chronic diseases. Biosorption is one alternative method for the removal of heavy metals from the environment using a biomaterial called biosorbent. Biosorption of Ni(II) ion using cacao fruit peel (Theobroma cacao) with variation of contact time, pH and concentration has been investigated. The concentration of Ni(II) ion before and after adsorption was determined by Atomic Absorption Spectrophotometer (AAS). The result showed that cacao fruit peel (Theobroma cacao) was able to adsorb Ni(II) ion and the optimum biosorption occured at a contact time of 10 minutes and at a pH of 5. Langmuir and Freundlich isotherm models were used to study the adsorption isotherm. Biosorption of Ni(II) ion by cacao fruit peel (Theobroma cacao) fulfilled the Langmuir isotherm with a biosorption capacity of 0,21 mmol/g. The functional groups involved in the  biosorption of Ni(II) ion by cacao fruit peel (Theobroma cacao) are –OH and N-H.

Abstract. Gold nanoparticles have been synthesized with simple and relatively safe method by using kaemferol and quercetin containing aqueous extract of Myrmecodia pendans (sarang semut plant). Under this method, it was able to obtain AuNPs and measured the size. The formation of the nanoparticles were identified by the color change (yellow to red) occurred in the chloroauric acid solution after additional aquoeos extract of sarang semut plant. The UV-Visible spectra and particle size analyzer indicated the successful formation of AuNPs with wavelength of 521.5 nm which was stable for 4 days, evidenced by the presence of particles with a size 53.2 nm. XRD analysis showed the difractogram peak of gold nanopartcle. The result of SEM analysis indicated gold nanopartcle surface with spherical and rod-like shapes. Glucose sensor utilized gold nanopartcle as catalyst with measurement range 2–5 mM and regresision 0,868, detection limit of sensor was in concentration 2-5 mM  was 7,5 mM with sensitivity 0,736 A.mM-1.mm-2. Glucose concentration obtained in blood serum was 78,48mg/dL. Gold nanoparticles is promising to detect blood sugar with simply, securely, low cost without using enzyme and harmful material.

Abstract

The principles of green chemistry in nanotechnology is one of the key issues in nanoscience research. Biosynthesis of nanoparticles using plant extract is an eco- friendly approach which eliminates the need for using physical and chemical techniques. A green synthetic route for the production of stable silver nanoparticles (AgNPs) by using aqueous silver nitrate as metal precursor and Myrmecodia pendans extract as bioreductor and PVA as stabilizer is being reported for the first time. In this case, the synthesis of silver nanoparticles (AgNPs) was carried out by reduction method. The bio-reduction and stabilization of so formed silver nanoparticles was monitored by UV-Vis spectrophotometry. Maximum absorption of AgNPs using Polyvinyl Alcohol (PVA) was at wavelength 408.50 nm, whereas that of AgNPs without using PVA was at wavelength of 408 nm. SEM images showed that the morphology of AgNPs was globular. An average size of silver nanoparticles using PVA and without using PVA was 78.3 and 76.1 nm, respectively. The results of X-Ray Diffraction (XRD) displayed the same peak pattern with that of the standard silver metal showing that the resultant particles are silver nanoparticles having FCC structure. Analysis of glucose levels in blood using silver nanoparticles based sensors showed glucose concentration of 71.71 mg / dL.

Abstract

Biosorption is an effective method for removal of heavy metals from their solutions. Biosorption of Cu (II) by contact time, pH, and concentration has been investigated. Concentration of Cu (II) ion before and after adsorption was determined using Atomic Absorption Spectrophotometer (AAS). The effect of the pH process was studied at pH of 2-7. The result showed that the optimum time for biosorption of Cu (II) ion by biomass dragon fruit was 10 minutes and pH 4 was the optimum pH of biosorption. Langmuir and Freundlich models were used for the adsorption of isotherm. Result showed that biosorption of Cu (II) by dragon fruit peel fit better the Langmuir model than Freundich model with the adsorption capacity (Qo) of 20.401 mg/g biosorbent. The result of FT-IR analysis showed that hydroxyl groups were responsible for the binding of Cu (II) ions.

Abstract

Molecularly Imprinted Polymers (MIP) are polymers with active sites that can recognize target molecules selectively. This study aims to determine the kinetics and adsorption capacity of MIP_DBP. The method used in the synthesis of MIP_DBP was precipitation polymerization using methacrylic acid (MAA) monomer, Ethyleneglycol Dimethacrylate (EGDMA) cross linker, DBP as a template molecule, and toluene as a solvent. The MIP_DBP obtained is a white solid. The results of the MIP_DBP adsorption kinetics test followed the pseudo-second-order kinetics model and the adsorption capacity according to the Freundlich isothermal adsorption model with the adsorption capacity value for DBP was 9.38 mg/g.
