Elution Behaviors of Stannous Ion by PSA on Chelating Resin
Ki-Won Cha*, Hyun-Cheol Choi
Amberlite IRC-718 킬레이트 수지에서의 주석(II)이온의 PSA(phenol sulfonic acid) 리간드에 의한 용리현상을 연구하였다. 0.10M Sn2+ 용액 일정량을 수지에 흡착시키고 시료를 녹인 여러 가지 농도의 PSA 용리액으로 용리하면 Sn2+ 이 두 개의 봉우리로 용리되고, 이 두 개의 봉우리 면적은 PSA의 농도에 따라 변한다. 이를 이용하여 Sn2+ 와 PSA 간의 착물의 안정도상수를 계산하였다. 그 값은 2.0 × 10-1이었다.

The elution behaviors of stannous ion by PSA(phenol sulfonic acid) as an eluent on chelating resin, Amberlite IRC-718 have been investigated. When 0.10 M stannous solution was adsorbed on the resin and eluted with various concentrations of PSA, the two peaks of stannous ion were appeared in the elution curve. These two peak areas were changed according to the PSA concentration. Using these results, the stability constant of the complex formation between Sn2+ and PSA was calculated. This value is 2.0 × 10-1.
