基于醋酸钠介质中，银（Ⅰ）催化过硫酸钾氧化荧光素反应，以２，２－联吡啶为活化剂，Ｔｒｉｔｏｎ Ｘ－１００为增敏剂，拟定了测定痕量银的新荧光速率法。本法由于添加 Ｔｒｉｔｏｎ Ｘ－１００表面活性剂，使得灵敏度提高了４倍，测定银含量线性范围为２～３２ μｇ／Ｌ，相对标准偏差为３．１％（ｎ＝９），检出限为１．７６ × １０－３（ｍｇ／Ｌ）。用于测定氯化银的溶度积和光谱感光板中的银，结果满意。 Based on the sodium acetate medium, silver (Ⅰ) catalyzes the reaction of potassium persulfate to oxidize fluorescein, the new fluorescence rate method for the determination of trace silver was developed by using 2,2-dipyridyl as activator and Triton X-100 as sensitizer . Due to the addition of Triton X-100 Surfactant, the sensitivity of this method is increased by 4 times. The linear range of silver content is 2 ~ 32 μg / L and the relative standard deviation is 3.1% (n = 9). The detection limit is 1.76 × 10 -3 (mg / L). Used to determine the solubility product of silver chloride and silver silver plate, with satisfactory results.
