研究了银对亚铁氰化钾与邻菲罗啉反应的催化作用 ,影响催化显色反应速度的最佳条件 ,建立了测定水中微量银的催化动力学光度法。方法的检出限为1 .2 0× 1 0 -6g/L,测定范围为 0 .0 1～ 0 .2 0 mg/L。已用于测定饮用水中的痕量银。
The catalytic effect of silver on the reaction of potassium ferrocyanide with 1,10-phenanthroline and the optimum conditions for the catalytic chromogenic reaction were studied. The catalytic kinetic spectrophotometry was established for the determination of silver in water. The detection limit of the method was 1.2 × 10-6g / L, the determination range was 0.01 ~ 0.220 mg / L. Has been used to determine trace silver in drinking water.
