Abstract:
Objective To develop a conductance-ion chromatography for simultaneous determination of 5 anions in drinking water. Methods The orthogonal experiment method L9(34) was used to select the optimum working conditions of IC-2000 ion chromatography. Under the founded chromatography condition, 5 anions in water samples were determined simultaneously after filtered with 0.45 ?m filter membrane. Results Both of the precision and accuracy of this method were desirable, all the relative standard deviation was less than 5.0%, the rates of recovery were 90%-106.7%, the correlation coefficient was more than 0.999 except NO2-(0.990 5). Conclusion This method is simple, accurate, quick and suitable for simultaneous determination of 5 anions in drinking water with no need of sample pretreatment.
