摘要
在０．００２％溴化十四烷基三甲铵（ＴＴＭＡＢ）－２０％ＨＣＩ体系中，Ｓｎ有一灵敏的吸附波，峰电位在－０．４７Ｖ（ｖｓ．Ａｇ／ＡｇＣｌ），线性范围２～１０００ｎｇ／ｍｌ。体系可用于岩石、土壤样品中微量Ｓｎ测定；机理研究表明，溴化一四烷基三甲铵通过诱导吸附ＳｎＣｌ提高测定的灵敏度。
new adsorptive polarographic wave of tin has been obtained in 0. 002%TTMAB-20%HCI system. The peak potential of the wave is-0.47V(vs.Ag/AgCl).A linear response between the peak height of the second derivative wave and the tin concentration was obtainedover the range of 2～1000 ng/ml. The method has been applied to the determination of tin inrocks. The function of the surfactant is discussed.
