The aim of the present work was to search a convenient, simple and inexpensive method to determine the metals in electroplating hydroxide sludges. The analytical methods are characterized by sensitivity, selectivity and accuracy but for economic reasons and of course the availability of equipments and products, the UV-visible spectrophotometry was used. We have undertaken the study of the influence of different cations present in the same solution on the determination of metal. After conducting several tests on solutions prepared in the laboratory and then on the solutions used to dissolve different samples of industrial waste, the result revealed that it is possible to use spectrophotometric method to assess the amount of metals in electroplating sludges, provided that we followed a welldefined scheme so as to avoid all the possible interference.
