Kinetics Study Of Au(Iii) Adsorption On Gallic Acid Intercalated Mg/Al-Hydrotalcite
Journal Title: Eksakta: Jurnal Ilmu-Ilmu MIPA - Year 2016, Vol 16, Issue 1
Abstract
Kinetics study of Au(III) adsorption on gallic acidintercalated Mg/Al-hydrotalcite (Mg/Al-HT) is conducted by means of interacting between the Au(III) solution with AuCl4 -species with GA intercalated Mg/Al-HT synthesized by direct coprecipitation method.The parameters used in the determination of adsorption kinetics is varied contact time of adsorption and for the determination of adsorption isotherm the varied Au(III) concentration at optimum contact time was used. Analysis of Au(III) in rest solution was performed by AAS. The adsorption of Au(III) by GA intercalated Mg/Al-HT was optimum at pH 3 and followed pseudo-second order kinetic and Langmuir isoterm models with rate constant (k) and adsorption capacity were 3.798x10-4 g.mg- 1.minute-1 and 625 mg.g-1,respectively.
