摘　　要：对GB6913.3-86《锅炉用水和冷却水分析方法磷酸盐的测定总磷酸盐》测定阻垢缓蚀剂中总磷酸盐误差大的问题进行研究,通过试验认为加热分解时间短是引起误差的主要原因,找出了消除误差的方法,从而拓展了该方法的适用范围。Directing against the problems of large error occurred in determination of total phosphorate （total phosphorus） in antiscale corrosion inhibitor by using National Standard GB 6913.3 -86 《Determination of phosphorate i. e. total phosphorate, in boiler water and cooling water by using analytical method》, a study has been carried out, and a method for eliminating the said error being found through test, thereby, extending the scope of application for the said method.
