摘要
在0.15mol/lNH_4Ac底液(pH6.5)中得到灵敏的铟(Ⅲ)-PAR 络合吸附波。其峰电位为-0.75V(vs.SCE)。峰电流与 In(Ⅲ)的浓度在1.0×10~■～、4.0×10~■mol/l 范围内成线性关系。用等摩尔系列法测得络合物的络合比为1:1。用循环伏安法,单扫示波极谱等研究了波的性质及其反应机理。
In a supporting electrolyte containing 0.15mol/l NH_4 Ac and 3×10^(-5)mol/l PAR,at pH6.5,a sensitive adsorptive complex wave of indium-PAR has been obtained by using single-sweeppolarography.The peak potential is-0.75 V(vs.SCE).The change of peak height with the con-centration of indium is linear in the range from1.0×10^(-R)to 4.0×10^(-(?))mol/l.In the solution thecomposition of the complex has been determinedto be 1:1.The mechanism of the electrodereaction is discussed
