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。
GB6913.3-86 “Boiler water and cooling water analysis of phosphate determination of total phosphate” Determination of scale corrosion inhibitors in the total phosphate error is studied, the test that the heating decomposition time is short of error The main reason is to find a way to eliminate the error, thus expanding the scope of application of the method.
