| Abstract: | Objective To set up a method for determination of iodide by ion chromatography with electrochemical detection. Method Iodide was detected by ion chromatography at eluent of 40mmol/L NaOH and velocity of flow was 1.0 ml/min , applied potential of 0.10V. Results The method showed broad linear range from 0.001mg/L to 0.50 mg/L and good correlativity (r>0.9999). The precision and accuracy was excellent (RSD<3.59%). The detection limits for iodide was 0.00007mg/L. Conclution Ion chromatography method with high sensitivity is simple and rapid, without any interference, and suitable to be applied in determination of iodide in drinking water. |
