| Abstract: | A analytical method of dual-wavelength spectrophotometry to simultaneously determine the iron and copper content in plating bath was established.2-(5-Br-2-pyridylazo)-5-diethylamino phenol(5-Br-PADAP)was used as chromogenic agent,Triton X-100(OP)as a solubilizer.By experiments,the optimum experimental conditions were confirmed,including the best amount of reagent,the stability of system and so on.In addition,the interference of coexistent elements were also studied.This method has higher sensitivity,lower d... |
