国内对于离子色谱法测定氰化物已有报道。本文在文献[1]的基础上,改用HPIC-AS_4型色谱柱分离,使工作效率提高了4倍。采用电化学检测,可以准确地测出水样中1μg/L的氰化物。方法简便、快速、准确,测定范围宽,高达1000μg/L的氰化物也能准确定量。一般水样在进样3 min后即可得到分析结果。
Domestic for the determination of cyanide ion chromatography has been reported. This paper based on the literature [1], using HPIC-AS_4 type column separation, the work efficiency increased by 4 times. Using electrochemical detection, can accurately measure the water sample 1μg / L of cyanide. The method is simple, rapid, accurate and has a wide range of determination. Cyanide up to 1000 μg / L can also be accurately quantified. General water samples can be obtained after 3 min in the analysis of the results.
