摘要
经蒸馏得到的碱性馏出液,用硝酸银标准溶液滴定。本方法重现性好,回收率满意,采用两种方法检验结果无显著性差异,检出限为0·0026mg/l,本法简便、快速、准确,能满足水质卫生标准要求,可适用于基层单位对水质中氰化物的测定,具有一定的实用价值。
Distilled liquid can be titrated by standard AgNo3 solution. This means has a good reproducibility and a satisfactory recovery rate. Both means suggests not so much difference. The detection limit is O. 0026mg/L This mean is quick convenient and precise. It can meet the demand of water protection. This method is operational for fundamental units to exam cyanide in the water, which is useful in the practical aspect.
