摘　　要：针对酸化回收尾液二次处理后废水中总氰测定的干扰物质去除方法进行了研究，提出了采用抗坏血酸、乙酸铅棉去除干扰的方法。经加入标准物质回收实验，回收率达到92％～99％。该方法可去除总氰测定中干扰物质的影响。A research on the determination of total cyanide in waste water treated secondarily by acidizing is carried out. A new method of secondary distillation after removing interfering material by ascorbic acid and lead acetate cotton is proposed. The recovery rate of standard material is 92 % - 99 %. And the method can remove the influence of the interfering material in total cyanide determination.
