Abstract

Adsorption of [AuCl4]- using aminobenzimidazole modified silica coated on iron sand magnetic material (MMSA) was carried out. MMSA was synthesized via sol gel process. MMSA was characterized by Fourier Transform Infrared (FT-IR) spectrophotometer and X-ray diffractometer. The ability of MMSA to adsorb [AuCl4]- was tested in a batch system as a function of pH, contact time, and adsorbate concentration. The adsorption kinetics was evaluated with pseudo first-order and pseudo second-order models, while adsorption isotherms was studied based on the Langmuir and Freundlich models. Characterization results indicated that MMSA was successfully synthesized. Adsorption kinetics of [AuCl4]- on BMSA followed pseudo second-order model with a rate constant (k) of 1.54 x 10-3 g mg-1 min-1. MMSA shows a linear plot of the Langmuir isotherm model with adsorption capacity of 16.90 mg g-1. The results obtained indicate that MMSA could used to adsorb [AuCl4]- or other metal ions in environmental with high acidity
