采用离子色谱法测定土壤浸提液中的Cl-和SO42-。选择2.0 mmol/L Na2CO3-1.3 mmol/L NaHCO3混合液为淋洗液，流速为2 mL/min，在此条件下，Cl-保留时间为1.96 min，SO42-保留时间约为12.26 min，Cl-，SO42-的质量浓度分别在2~8，10~30 mg/L范围内与色谱参数线性相关，相关系数分别为0.9994和0.9997，Cl-，SO42-的平均加标回收率分别为93.8%，105.4%，测量结果的相对标准偏差均小于1%（n=6）。该法适用于土壤中Cl-和SO42-的测定。

Ion chromatography was used to detect chloride ion and sulfate ion in soil. The mixture of 2.0 mmol/L sodium carbonate and 1.3 mmol/L sodium bicarbonate solution was selected to be mobile phase, and the flow rate was 2 mL/min. In such circumstances, the retention time of chloride ion was 1.96 min, sulfate ion was about 12.26 min. A good linear relationship was obtained between the mass concentration and the chromatograph parameter in the range of 8-10 mg/L Cl-and 10-30 mg/L SO42-, the linear correlation coefficients were 0.999 4 and 0.999 7, the recovery rates were 93.8%and 105.4%, respectively. The measuring relative standard deviation were all less than 1%(n=6). The method was suitable for the determination of Cl-and SO42-in soil.
