Abstract

In the present investigation, a technology has been developed for the separation of tin which will be applied for its recovery from the touchscreen of the mobile(E-Waste) to the extent of 92.14 ± 2.28% employing batch adsorption method. Synthetic three component adsorbing material, zirconium phosphosilicate (ZPS) material has been used as a solid phase in the adsorption. Amount of tin recovered by adsorption has been determined by using UV-Visible Spectrophotometer. (Equitronics , EQ-825) and 8.5x10-3 M Sodium morpholine thiocarbamate solution as a spectrophotometric reagent. Sn(II) forms a colored complex at slightly acidic medium with the solution of the reagent having maximum absorption at 390nm. The technique is optimized by varying amount of adsorbent (ZPS), pH, time of adsorption, etc. Under the optimum conditions of adsorption, an effect of various anions and cations in the adsorption of Sn (II) also has been studied. Interfering cations has been masked by using suitable masking agents so as to make the process more selective. It has been observed 100mg of adsorbent is sufficient to recover 5µg of tin at pH 2 and contact time of 6.0 min. The method thus developed has been applied to recover an amount of tin from the water samples spiked with tin and Indium.
