| Abstract: | The quantitative determination method has been established for four anions including fluoride, chloride, phosphate, sulfate in mineral water by ion chromatography. Ion chromatography is ICS-1000 with chromatographic column of lonpac ASI4A and suppressor column of ASRS ULTRA II. The eluent is the mixed solution of 8.0 mmol·L^-1 Na2CO3-1.0 mmol·L^-1 NaHCO3. The eluent is performed at a flow rate of 1.0mL- min^-1. The linear range is wide, linear correlation is high（linear correlation coefficient is 0.9992 - 0. 9999）. The determination limit is 0.0111 - 0.0522mg.L^-1. RSD is from 0.28% to 0.91%, and the recovery ratio is 98.97%- 103.4%. The suppressor column is regenerated without adding additional reagents. The method is proved to be simple, high sensitive, accurate and quick. |
