| Heated to boiling at the state, in order to dilute sulfuric acid as the medium case, Cu (¢ò) on persulfate oxidation of Acid Chrome Blue K reaction system has the role of catalytic bleaching to study the optimization of reaction conditions and kinetic parameters, set up A catalytic kinetic spectrophotometric determination of copper by new methods, measurement of copper by this method is simple, high sensitivity, low detection limit, analysis and low cost. The method detection limit is? ? g / mL, linear range of 0 ~ 1.0¦Ìg/25mL, method has been applied to the determination of drinking water will be able to obtain satisfactory results. |
