铟—4-(2-吡啶偶氮)间苯二酚络合吸附波的研究
Studies on the adsorptive complex wave of in dium-4-(2-pyridylazo)resorcinol(PAR)
【摘要】 在0.15mol/lNH4Ac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。
【Abstract】 In a supporting electrolyte containing 0.15mol/l NH4 Ac and 3×10-5mol/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-Rto 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
