摘要
在NH_4OH-NH_4 CI-NH_2 OH·HCL介质中,钴(Ⅱ)与5-Br-PADAP配合物产生一个灵敏的吸附波,峰电位为-0.72V(vs.SCE),钴含量为0—20ppb时,波高与钴浓度成正比。
In the Co (Ⅱ)-5-Br-PADAP-NH_2OH.HCl-NH_4 OH-NH_4 Cl system a sensitive adsorptive catalytic wave of cobalt is produced. The peak potential appears at -0.72V (vs.SCE). The most suitable suPporting electrolyte solution is composed of 1.43x10^(-6)mol/L5-Br-PADAP, 0.73mol/ L NH_4 OH, 0.02mol/L NH, Cl, 0.13mol/L NH_2OHHCl. The wave height is directly proportional to the concentrations of cobalt in the range of 0—20ppb.
