Objective A method for simultaneous determination of MBAA,DBAA,DCAA,TCAA and ClO2-in drinking water was established by ion chromatography.Methods The water samples were determined by 0.22 μm qeuosystem filter membrane with a volume of 500 μL.The samples were rinsed with KOH solution gradient and separated by IonPac AS19 anion column.The column temperature was set at 30℃,and the current of the inhibitor was 75 mA.Results The results showed that the linearity ranges of ClO2-,MBAA,DBAA,DCAA and TCAA were found in the range of 10～1000 μg/L,r>0.9990,with detection limits(3 S/N)of 0.32,0.76,1.30,0.69,1.58 μg/L.The standard recoveries were 80%～110%and RSD(n=6)of the determined values were all less than 5.0%.Conclusion The method was simple,sensitive,can meet the detection requirements of four kinds of Haloaeetic Acids and Chlorite in drinking water.The method can be used for the determination of kour kinds of haloaeetic acids and chlorite in drinking water.
