Based on that, we have investigated the extraction of copper, lead and nickel with N-methyl-N,N,N-trioctyloctan-1-ammonium chloride from the mixture of elements prepared in artificial manner. We investigated the influence of HCl concentration and salts (NaCl, NaI and CH 3 COONa) concentration in extraction of three elements (copper, lead and nickel) from water solutions. All extractions were done from HCl water solutions with c = 2, 4 and 6 mol dm -3 and in presence of NaCl, NaI and CH 3 COONa salts, which we prepared in different concentrations. Extraction of copper from NaCl solution move from 12.5-76.8%, from NaI solution 100% and from CH 3 COONa solution 5.1-88.2%. Extraction of lead from NaCl solution move from 0-48.5%, from NaI solution 100% and from CH 3 COONa solution 32.6-82.1%. In solutions of NaCl, NaI and CH 3 COONa we cannot extraction the nickel. ------------------------------------------------------------------------ * Corresponding authors.
