Abstract
스칸듐을 Methyl Thymol Blue(MTB)를 사용하여 가시선 흡수분광법으로 정량하는 새로운 방법을 확립하였고 주석슬러그에 스칸듐은 음이온교환수지와 용리액으로는 황산암모늄과 황산의 혼합용액을 사용하여 분리 회수하였다. 스칸듐과 MTB간의 착물의 결합비는 1:1이었고 최대흡수파장은 585nm이고 몰흡광계수는 2.0 × 104 l·mol-1·cm-1이다. 주석슬러그 용액을 음이온교환수지에 흡착시키고 위의 용리액으로 용리시키면 스칸듐 이외의 공존이온은 빨리 용출되고 늦게 용출되어 분리 회수된다.

A new spectrophotometric determination method of scandium in the tin slag solution has been investigated using methyl thymol blue as a colorimetric reagent. Scandium is recovered by the anion exchange resin, Amberlite IRA 400, using the mixture solution of ammonium sulfate and sulfuric acid and an eluent. The mole ratio of complex of scandium and MTB at pH 6 is 1 to 1 and the wave length of the maximum absorbance is 585 nm and the molar absorptivity at this wave length is 2.0 × 104 l·mol-1·cm-1. When tin slag solution is loaded into anion exchange resin and eluted, ions in the solution except scandium ion are eluted rapidly and scandium is eluted lately. So scandium is recovered easily.
