The adsorption and desorption characteristics for indium recovery from aqueous solutions using commercially available iminodiacetate resin Lewatit (R) TP207 (TP207) was investigated. The polymer resin had indium adsorption capacity of 55 mg(In/gTP207) at 25 degrees C and desorption efficiency of 99% in pH 0.8 acid aqueous solution. Furthermore, it was observed that TP207 had performance result of 99% after four times cycle test to confirm the reusability. The results show that TP207 polymer resin provides high efficient desorption property in acid solution and reusability in cycle test of adsorption-desorption. These results offer a simple and effective recovery process for indium. (C) 2016 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V. All rights reserved.
