摘要
本文提出了钒(V)-5-Br-PADAP-H_2O_2三元配合物的配位吸附波。在O.60M磷酸底液中,该波的峰电位为-0.05V(vs SCE),在8.00×10^(-8)～2.00×10^(-5)M浓度范围内与峰电流呈线性关系。对极谱波的电流—电位性质进行了研究,求得了配合物的组成、表观稳定常数和离解及生成速率常数。
A method has been elaborated utilizing the adsorptive-complex polarographic wave of V(V) in 5-Br-PADAP-H_2O_2-H_3PO_4 medium. The peak current is linearly related to the concentration of V in the range of 8×10^(-8)—2×10^(-5) M. The behaviour of currentpotential curve was studied and the composition, stability constant(K)and dissociation constant(kb) of the complex were determined.
