| Abstract: | 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... |
