摘要
利用氟离子选择性电极标准曲线法测定电镀铬废水中氟离子含量,得标准曲线方程为y=59.6x?2.2,相关系数接近于1,方法误差为2.0%～5.4%。该法简便、快捷、准确,其测定结果与氟试剂分光光度法的测定结果一致。
A method for the determination of F- in chromium-electroplating wastewater was established based on fluoride ion selective electrode by standard curve. The standard curve regression equation is y = 59.6x - 2.2, and its relativity of the linear regression equation approaches 1.000. The absolute error of the testing ranges from 2.0% to 5.4%. The method is simple, rapid and accurate. The determination result of the method accords with that obtained by spectro- photometry with alizarin complexone as chromogenic reagent.
