有关利用络合物的极谱催化波连续测定镍,钴的报道较少。在研究铜-Zincon的极谱行为时,我们发现NH_4Cl-Na_2SO_3(pH=6.5～7.5)底液中当Zincon浓度>4×10~(-5)·mol/L时,单扫描示波极谱仪上有两个峰,其峰电位分别为-0.42V和-0.56v(vs.
There are few reports about the continuous determination of nickel and cobalt by polarographic catalytic wave using complex. When investigating the polarographic behavior of copper-Zincon, we found that the single-sweep oscillopolarographic (PLS) spectra of Zinc in NH_4Cl-Na_2SO_3 (pH = 6.5 ~ 7.5) at Zincon concentration> 4 × 10 ~ (-5) The instrument has two peaks, the peak potential were -0.42V and -0.56v (vs.
