摘要
研究了在表面活性剂存在下 ,苦味酸与氰化物的显色反应 ,试验了测定的最佳条件 .在表面活性剂存在下 ,方法的灵敏度提高 2 .5倍 ,在 0～ 0 .6μg/m L范围内符合比耳定律 .方法应用于实际水样的分析 ,结果满意 .
The solubilization and sensitization effect of cationic surfactant were investigated in determination of cyanide with pricricacid. A new method to determine the cyanide in waste water with picric acidCTMAB was established by a serial experiments in different conditions. The new method increases the sensitivity and accords with the LamgberBell's law in range of 0~0.6 μg/mL. The method is used to determine cyanide in water with satisfactory results.
