摘要
本文研究了在表面活性剂氯化十六烷基吡啶（ＣＰＣ） 存在下， 以茜素紫为显色剂测定微量锗的反应条件和络合物组成。试验表明， 络合物在５４０ｎｍ 处有最大吸收， 方法灵敏可靠。在试验酸度下（ｐＨ＝ １－８～２－４） ， 大部分常见元素不干扰测定，
In this paper,in the presence of cationic surfanctan CPC,the condition and composition of the ternary complex for determination of germanium(IV)with Gallein have been put forward.This method is charcterized by high sensitivity and good selectivity.The maximum absorption of complex compound was at 540nm.The proposed method has been applied to determination of trace amount of Ge(IV)in coal ash and alloy with satisfactory results.
