The simultaneous determination of copper and silver by catalytic kinetic spectrophotometric method was realized based on the catalysis of Cu(Ⅱ) and Ag(Ⅰ) to the reaction of o-methoxyphenolammonium persulfate in boric acid and sodium hydroxide buffer medium. The optimum condition of reaction was studied. The calculaion results of using multivariate linear regression. Kalman filter andartificial neural network were compared, it indicated that the result of artificial neural network was the best for the determination in synthetic samples. This method has been used to determine copper(Ⅱ) and silver(Ⅰ) in offscum of plumbum-zinc mine with saisfactory results.
