| Abstract: | A method for determination of iodide in a variety of water by ion chromatography is presented.It was based on an IonPac AS19 Column with KOH as eluent and a conductive detector.This paper discussed the interference and elimination, the optimization of chromatographic conditions, the analysis methods of the linear and the detection limit, precision, accuracy, etc.This method was applied to determine iodide in a variety of water.The results show that this method is not subject to other anion interference, and it has low detection limits, wide linear range and good correlativity(R2 =0.999 9).The precision and accuracy were excellent.This method is simple and accurate.It was applicable to determine iodide in a variety of water. |
