Au(Ⅲ)—PAR络合吸附波的研究
Studies on adsorptive-complex wave of gold and 4-(2-Pyridylazo) resorcinol
【摘要】 金与PAR(4-(2-吡啶偶氮)间苯二酚)的络合物在HAc-NaAc底液中于-0.43V处有一灵敏的络合吸附导数波,波高与金浓度在0.1～1.8μg/ml范围内呈线性关系,可用于分析测定。研究了该波的性质及电极过程,测定了该络合物的组成及表观稳定常数。
【Abstract】 The adsorptive-complex wave of gold and 4-(2-pyridylazo) resorci-nol (PAR) at -0.43V(SCE) in HAc-NaAc base-solution is studied. The wave height with gold concentration is good linear in the range of 0.1-1.8μg/ml. Apparent stability constant of complex was calculated to be 2.0×10-5.
