The indirect voltammetric determination of trace sulfate (2.0×10^(-6)~4.0×10^(-5) mol/L ) with the adsorptive complex wave of lead(Ⅱ)-tetrakis (4-trimethylammonium phenyl) porphyrin (PbTTMAPP) is reported....The indirect voltammetric determination of trace sulfate (2.0×10^(-6)~4.0×10^(-5) mol/L ) with the adsorptive complex wave of lead(Ⅱ)-tetrakis (4-trimethylammonium phenyl) porphyrin (PbTTMAPP) is reported.This method has been used for the analysis of natural waters with satisfactory results.展开更多
In our previous papers, the isonuclear complexes of RE (Ⅲ)-Ni (Ⅱ) (or Co(Ⅱ))-ALC had been studied by single-sweep polarograph. In the present note, the polarographic adsorptive complex wave of RE (Ⅲ)-Cu (Ⅱ)-ALC i...In our previous papers, the isonuclear complexes of RE (Ⅲ)-Ni (Ⅱ) (or Co(Ⅱ))-ALC had been studied by single-sweep polarograph. In the present note, the polarographic adsorptive complex wave of RE (Ⅲ)-Cu (Ⅱ)-ALC is reported. The mechanisms of the two are different, the former being the reduced wave of ligand (ALC),展开更多
