Abstract

In order to recover tin from the waste tin plating solution, we used the ion exchange method using three types of ion exchange resins. The ion exchange resin with tertiary functional group(Lewatit TP 272) has not adsorption ratio of tin. The ion exchange resin with iminodiacetic functional group(Lewatit TP 207) has high adsorption ratio of tin, but impurity content in the recovered tin solution was relatively high. Whereas, in case of the ion exchange resin with functional group of ethylhexyl-phosphate(Lewatit VP OC 1026), adsorption ratio of tin was less than that of Lewatit TP 207. However, it was possible to remove impurities in the recovered tin solution by controlling the pH of the solution. High purity tin solution can be recovered by removing the organic materials with water washing process.

주석도금폐액으로부터 이온교환수지를 사용하여 주석 회수에 대한 연구를 실시하였다. 3종류의 이온교환수지를 사용하여 기초 실험한 결과 tertiary 기능기를 가진 이온교환수지(Lewatit TP 272)는 주석을 흡착하지 못하였고, iminodiacetic기능기를 가진 이온교환수지(Lewatit TP 207)는 주석의 흡착율은 높으나, 회수된 주석용액 내 불순물 함량이 높았다. Ethylhexyl-phosphate의 기능기를 가진 이온교환수지(Lewatit VP OC1026)를 사용한 경우, 주석의 흡착율이 iminodiacetic기능기를 가진 이온교환수지 보다 낮았으나 pH 조절에 따라 회수된 주석용액 내 불순물의 제거가 가능하였다. 또한 이온교환수지에 흡착된 유기물의 경우는 수세를 통해 제거를 함으로써 고순도 주석용액으로 회수가 가능하였다.
