Water quality - determination of dissolved anions by liquid chromatographyofions - part 2 : determination of bromide, chloride, nitrate, nitite, orthophosphate and sulfate in waste water.
T he concentrations ofions in electrolyte were measured by normal analysis method, and the content of oxygen in electrolysis gas was measured by gas chromatography.
