在一定条件下,用方波极谱法研究了Au(Ⅲ)和Au(Ⅰ)与4-(2-吡啶偶氮)-间苯二酚(PAR)络合时,Au(Ⅲ)和PAR络合物在-0.35V和-0.42V处有两个明晰的还原峰,其中第二个还原峰的电流(Ip)与Au(Ⅲ)的质量浓度在0.50~4.0μg/mL范围内呈线性关系,检出限为0.010μg/mL;Au(Ⅰ)与PAR络合物在-0.38V处有一个明晰的还原峰,峰电流(Ip)与Au(Ⅰ)的质量浓度在0.050~2.0μg/mL范围内呈线性关系,检出限为0.003 0μg/mL。用该方法成功地分析了金矿粉处理后滤液中金的价态和含量。
Under certain conditions, the complexation of Au (Ⅲ) and Au (Ⅰ) with 4- (2-pyridylazo) -resorcinol The complexes have two clear reduction peaks at -0.35V and -0.42V, and the second reduction peak current (Ip) and the mass concentration of Au (Ⅲ) linear in the range of 0.50 ~ 4.0μg / mL The detection limit was 0.010μg / mL. The complex of Au (Ⅰ) and PAR had a clear reduction peak at -0.38V. The peak currents (Ip) and Au (Ⅰ) were in the range of 0.050-2.0μg / mL linear relationship between the detection limit of 0.003 0μg / mL. The method was used to successfully analyze the valence and content of gold in the filtrate after gold ore processing.
