摘要
Abstract
A method for rapid determination of trace cyanide in drinking water is established using an ion chromatography-amperometric detector. The minimum detection limit of this method is 0.17 μg/L (signal-to-noise ratio S/N =3) , the minimum limit of quantification is 0.56 μg/L (signal-to-noise ratio S/N = 10) , and has a good linearity over a concentration range of 0-150 μg/L, and it is not easy to be affected by the conventional anions, sulfides and thiocyanides in drinking water. The test results align with the results of the gas chromatographic GB method when testing the actual samples. Experiments show that the method has good repeatability, low detection limit, high precision and high accuracy. It is not easily affected by other ions during the detection. It is suitable for the determination of cyanide content in drinking water.关键词
