Abstract

In this study, we developed Alamine-336-impregnated alginate capsule (Alamine-336- AC) by using a simple method. Alamine-336 was used as a model solvent extractant because it has good selectivity toward gold. Alamine-336-AC was prepared at different ratios of A (mixture of 1% CaCl2 and 2% carboxymethyl cellulose) and B (Alamine-336) solutions. A comparative study revealed that the ratio of 9:1 (A:B) was the best condition for fabricating Alamine-336-AC. Microscope images revealed that Alamine-336 was well dispersed in the Alamine-336-AC. The maximum of gold uptake by Alamine-336-AC was 284.1 mg/g, which was about 5 times higher than those of Pt and Pd. Kinetics of adsorption was also investigated.
