用GB6913.3-86测定阻垢缓蚀剂中总磷存在的问题与改进
PROBLEMS EXISTING IN DETERMINATION OF THE TOTAL PHOSPHORUS IN ANTISCALE CORROSION INHIBITORS BY USING GB69 13.3-86 AND IMPROVEMENT THEREOF
【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。
【Abstract】 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.
