摘　　要：采用AgNO3对氰化液中的CN-进行准确测定,采用KCN对氰化液中的Ag+进行准确测定。考察了溶液酸度、共存离子干扰对测定的影响。此法简便快速,检出限可达4μg,适用于常量、微量分析,适合野外现场快速分析。Determination of cyanide and silver from cyanide solution was studied by reaction of silver nitrate with cyanide, and potassium cyanide with silver. Effect of acidity and co-existing ions on the analysis was investigated. Result showed that the method was simple and fast, with detected limitation of 4 μg.
