摘　　要：建立了离子色谱法测定循环水中Cl-和PO3-4的方法。采用AG23阴离子交换色谱柱,使用过滤头和"固相萃取柱"组成的联合装置除去固体杂质和有机杂质。以1mmol/L NaHCO3和4.5mmol/LNa2CO3为淋洗液,流速为1.2mL/min,柱温为35℃。各组分的相关性好(r>0.999),组分的检出限均<0.10mg/L,各物质的加标回收率为95.2%~99.8%。该方法快速、灵敏、准确,可用于循环水中Cl-和PO3-4的分析。In the paper,established a method of determing chloride ion and phosphate ion in recycled water by ion chromatography（IC）.Using the AG23 anion exchange chromatography column and the joint device of filtration and＂solid-phase extraction column＂,removed the solid impurities and organic impurities.Taking 1mmol/L NaHCO3 and 4.5mmol/L Na2CO3 as eluent,flow rate is 1.2mL/min,the column temperature is 35℃.The correlation,r,is more than 0.999,the detection limit is less than0.10mg/L,the recovery rate is between 95.2% to 99.8%.This method is rapid,sensitive,accurate,and can be used for analysis of circulating water of chloride ions and phosphate ions.
