摘要
本文研究了钼与PV-CTMAB的显色反应,结果表明该体系灵敏度虽高,选择性却很差。为此,本文采用硅胶-TBP反相萃取层析法,使Mo、Sn与Ti、W、Ge、Cu、Pb、Zn、Ni、Mn、Fe等分离,提高了方法的选择性.并应用于含上述诸多离子的复杂试样——水系沉积物、岩矿中微量Mo、Sn的测定,取得满意的结果。
In this paper chromogenic reaction of Mo and PVCTMAB system was studied. The results indicate that the sensitivity of the system is high, but the selectivity is low. The silica gel-TBP reversed phase extraction chromatography has been used to separate Mo, Sn from Ti, W, Ge, Cu, Pb, Zn, Ni, Mn and Fe resulting in improved selectivity of the system. The method has been applied to the de termination of trace Mo and Sn in river sediments, minerals and rocks with satisfactory results.
