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。
Chloride ion selective electrode was used to determine the content of chloride ion in drilling wastewater. Two methods were used to pretreat the drilling wastewater. The linear relationship between chloride ion concentration in the range of 0 ~ 250mg / L was good with a correlation coefficient of 0.9968. And reproducibility and selectivity is good, the precision and accuracy is better.
