研究了三唑螯合树脂(AMTR)在盐酸介质中分离富集金,吸附的容量大,选择性高,无污染。同时研究了分离后在盐酸介质中,在抗坏血酸(vc)存在下痕量金(Ⅲ)催化溴酸钾氧化偶氮氯膦S褪色的指示反应及其动力学条件,据此建立测定痕量金(Ⅲ)的新方法。方法的检出限为4.16×10-7 g/L,测定范围为0—70 mg/L,用于样品的测定,结果满意。 The triazole chelate resin (AMTR) was studied for the separation and enrichment of gold in hydrochloric acid medium. The adsorptive capacity, selectivity and non-pollution were high. At the same time, the reaction conditions and kinetic conditions for the chlorination of chlorophosphonazo S catalyzed by trace potassium (Ⅲ) catalyzed by potassium bromate in hydrochloric acid medium were studied in hydrochloric acid medium after separation. The determination of trace gold (Ⅲ ) Of the new method. The detection limit of the method was 4.16 × 10-7 g / L, and the determination range was 0-70 mg / L, which was used for the determination of samples with satisfactory results.
