Abstract:
Objective To establish the method for determination of bromate in drinking water by eluent generator suppressed conductivity ion chromatography.Methods Used application of American Dionex ICS-2100 ion chromatograph and EGC-III eluent automatic generator for ion chromatography gradient elution method to do determination of bromate in drinking water [IonPac AS19 (4×250 mm)].Eluent generator produced KOH online,gradient elution,Flow rate:1.0 ml/min.Results The method was linear in the range of Y =-0.000 609 7+0.000 873 1X,r =0.999 9,high precision (CV% < 1.5).The samples average of recovery was 99.5%~100.8%.The lowest detection limit was 0.50 μg/L.Conclusion Ion chromatog-raphy gradient elution method for the determination of bromate in drinking water was simple,rapid,and sensitive.It can be suitable for determination of bromate in drinking water.
