摘要
辅锅炉水(B14001)在用硫-钼-偏方法测定PO43-时,颜色为蓝色,根据原理应该为黄色的磷钒钼酸化合物,经过分析,是高压脱氧槽联胺含量太高所致。通过探讨残留联胺对磷酸盐的影响大小,改为用循环水总磷测定方法后对结果有很好的选择性和重现性。
Auxiliary boiler water B14001）in the determination of PO34- by sulfur-molybdenum-bias method,the color is blue and,according to the principle,it should be yellow phosphomolybdic acid compound.By analysis,it is caused by the high content of high pressure deoxidized trough diamine.To study the effect of residual diamine on phosphate,the method of determination of total phosphorus in circulating water has good selectivity and reproducibility.
