摘　　要：为准确测定设备冷却水系统(磷酸盐-铁体系)中的痕量硼,研究了电感耦合等离子光谱仪法(ICPOES)在设备冷却水系统中痕量硼测定的应用。对该方法中元素分析谱线、等离子体参数等进行研究。试验结果表明,在设备冷却水磷酸盐及铁含量最高的基体环境中,在选定的最佳条件下,硼检出限为85μg/L,方法定量限为285μg/L,加标回收率为98%～104%。For accurate determination of trace boron in the equipment cooling water system（phosphate-iron matrix）,the application of the standard addition method and ICP-OES was studied.The element analysis spectrum line and plasma parameters are studied with this method.The test show that,in the substrate environment with the highest concentration of phosphate and iron content,the method detection limit was 85 ug/L,the quantitative limit of the method was 285 ug/L,and the recovery rate is 98%～104% under the best conditions of the instrument.
