CTMAB－对偶氮水杨酸苯基萤光酮光度法测定微量锗

Spectrophotometric Determination of Microamounts Germanium with ρ CHPA PF in the Presence of CTMAB

分析了溴代十六烷基三甲基铵（ＣＴＭＡＢ）存在下，对偶氮水杨酸苯基萤光酮（ρ－ＣＨＰＡ－ＰＦ）与锗的显色反应，制定了一种简便，灵敏测定锗的光度分析方法，用于矿样中微量锗的直接测定。

This paper described a chromogenic reaction of Ge (Ⅳ) with ρ CHPA PF in the presence of CTMAB.The germanium complex exhibited an absorption maximum at 510 nm,Beer's law is obeyed in the range Ge(Ⅳ)0～0.28 ng/L.This method was applied to direct determination of Ge(Ⅳ) in minerals withont separation.
