5-Br-PADAP-OP体系快速联测Cu^(2+)、Zn^(2+)

A QWICK METHOD FOR DETERMINING COPPER AND ZINC IN 5-BR-PADAP SYSTEM

在OP乳化剂存在下．Cu2+、Zn2+分别可与5－Br－PADAP形成红色络合物．且用有机试剂对铜的配合物进行分解，可测定Zn2+、Cu2+及Zn2+与显色剂的络合物的吸光度，用差减法求得铜锌含量．

Op as a emuisifying agent in the system of copper,zinc and 5-Br-PADAP can increase misci bility in water solution.Both copper and zinc can form a red complex with 5-Br-PADAP.An or ganic agent to be found can deform the complex of copper.So zinc and copper complex and zinc complex can be determined through the photometric method.
