摘要
在PH=9.26的NH_3—NH_4Cl缓冲液中,Pd有一络合吸附波,其峰电位为—0.75V(vs.SCE),加入DEHSO后,出现Pd—DEHSO络合吸附波,峰形较前者好,峰电位为—1.05V(vs.SCE)。在1.88×10^(-6)mol/L—1.13×10 ~3tool/L之间有良好的线性关系,可准确用于Pd的测定。
In NH_3-NH_4C1 buffer solution of PH=9.26,Pd gives a complex adsoptive wave with peak potenrial of-0. 7V(vs. SCE). After the addition of DEHSO,a complex adsorptive wave of PaDEHSO appears at peak potential-1. 05V(vs. SCE). The form of latter peak is better than that of the former one. The peak height is directly proportional to concentration in the range between 1. 88×10^(-6) Mol/L- 1. 13×10^(-3)Mol/L,it shows to have good linearity and to be available to accurate determination of Pd.
