Abstract: Interferences of selected transition and noble metals and hydride-forming elements in the electrochemical generation of selenium hydride in continuous flow mode were studied. For comparison the study of these interference effects in the chemical generation of selenium hydride was also performed under the same experimental conditions. The attention was concentrated upon the interferences of 16 selected transition and noble metals and hydride-forming elements: Cu(II), V(V), Cr(lII), Mn(II), Fe(II), Co(II), Ni(II), Ag(I), Cd(II), Au(III), Pb(II), Hg(II), Sn(II), As(III), Sb(III), Te(IV). The influence of the interference on the analyte signal (50.0 µg dm-3 Se(IV)) was measured in the concentration interval 0-20.0 µg cm-3. The transition and noble metals were divided into three basic groups according to their behaviour during electrochemical and chemical generation of H2Se.
