【摘要】 在0.24mol/L酒石酸钾钠-0.15mol/L KOH及pH 9.2的NH₄Cl-NH₃·H₂O介质中,Au（Ⅲ）与四（4-三甲铵苯基）卟啉（简称T（4TMAP）P）的配合物于-1.72V（vs·SCE）处产生一灵敏的吸附波,波高与Au浓度在0.001～0.25μg/ml内呈直线关系。用泡沫塑料分离富集后,测定地质样品中的痕量Au,结果满意。更多还原

【Abstract】 In Seignette’s salt solution, the complex formed from gold and meso-tetra (4-trimetylammoniumphenyl) porphyrin produces a clear, sensitive and steady polarographic adsorptive wave at Ep=-1.72V (TO. SCE). The peak height is directly proportional to gold concentration over the range 0.001-0.25μg/ml. The method has been used to determine trace gold in ores after selective enrichment with fqamed plastics.更多还原
