Abstract
The conditions for elimination of interference of surface-active organic substances (for e.g., natrium laurilsulfate) or humic acid on anodic peaks of Zn, Cd, Pb and Cu were investigated. Interference of these substances is related to their adsorption on working electrode and formation of strong ion-metal complexes. Both of them are obstacles to reduction of metal ions on the working electrode. Aiming at interfering substances destruction in solutions, the effect of ozone and UV irradiation from mercury quartz lamp (λ∼254 nm) and KrCl-excilamp (λ∼222 nm) was studied. It is presented that KrCl-excilamp is mostly efficient for surface-active organic substances destruction. Effect of Hg-lamp under TiO2 additions in solution is less efficient. And ozone treatment of the sample is not in the least efficient here, except for Cu. All three ways can bo used for Metal+humic acid complexes destruction.
