Brief content The content of Sn, Pb, Ni, Zn and Fe in deposits of copper obtained by electrodeposition from acidic solution resulted in the recycling of Waste Printed Circuit Board were determined by inductively coupled plasma optical emission spectrometry. The determinations were carried out using a simultaneous Spectro CIROSCCD spectrometer equipped with an axial viewing torch. The copper samples were dissolved in aqua regia, and the metals were determined in optimum working conditions of plasma torch. Contents up to 1.5% Pb, 0.8% Sn, 1% Zn and 0.3% Ni and Fe were found. The copper purity was in the range 97 – 99.8%. The limit of detection and quantification of metals were calculated in deposits of copper.
