摘要
利用氯离子选择性电极测定钻井废水中的氯离子含量,分别用两种方法对钻井废水进行了预处理,氯离子在0～250mg/L的范围内线形关系良好,相关系数为0．9968,并且重现性和选择性良好,精密度与准确度较理想。
The quality of PCI-1 chlorine ion selective electrode was studied. It has been used in the determination of chlorine ion content of the drilling waste water. Before determination, pre-treatment of the drilling waste water was conducted by two different methods. The results show that the linear relation of chlorine ion concentration is between 0- 250 mg.L-1, the interrelated coefficient gets 0.9968.The electrode showed high selectivity and the accuracy and precision are satisfactory.
