Abstract:
Objective To determine multiple inorganic anions in drinking water with ion chromatography,such as F~-,Cl~-, NO_2~-,Br~-,HPO_4~(2-),NO_3~-,SO_4~(2-).Methods The ion chromatography was used.The optimized conditions were explored.Results Under the selected flow rate(1.5 ml/min),the optimal concentration of eluent NaHCO_3 and Na_2CO_3 was 2.0?10~(-3)and 3.0?10~(-3) mmol/L,under the concentration of eluent,the optimum pump flow rate was 1.5 ml/min,the recovery rate was 94.69%-102.20%. Conclusion This method is applicable to the determination of multiple inorganic anions in drinking water.
