Title:: Enrichment and Separation with Sulfhydryl Cotton-Micellar Solubilization Spectrophotometry of Cu (Ⅱ) in Sea Water

摘要:: 本文以胶束增溶分光光度测定铜(Ⅱ); 在pH=9.0,OP存在下,Cu(Ⅱ)与5-Br-PADAP以1:2形成红紫色络合物,pH=8.1-10.0范围内吸光度基本不变,ε552=9.15×104,Cu(Ⅱ)0—1цg/ml符合比耳定律,在水中的常见金属离子干扰用巯基棉分离,本法用于海水中微量铜Cu(Ⅱ)的测定,得到了满意结果。

Abstract:: This paper describes a method of micellar solubilization spectrophotometry for the Cu(Ⅱ) determination. The method is based on the formation of a red-violet 1:2 (metal: ligand) complex from reaction of Cu(Ⅱ) with 2-(5-Br-pyridylazo)-5-diethylaminophenol (
