摘要
通过对经硫酸汞络合后的含氯样品CODcr的测定,指出了硫酸汞与氯离子的量为20: 1时,对氯离子能达到较好的屏蔽效果,使干扰程度降到较低水平。
This paper,based on the determination of COD cr sample containing chloride completed by HgSO 4,points out that when HgSO 4:CL - is 20:1,the former can reach a better screening effectiveness,thus reducing the CL - interference to a lower level.
