摘要

The determination of inorganic anions in environmental waters, such as drinking water, surface water, and wastewater, is perhaps the most widely used application of ion chromatography (IC) worldwide. The U.S. National Primary Drinking Water Standards specifies a Maximum Contaminant Level (MCL) for a number of inorganic anions, including fluoride, nitrite and nitrate. The MCLs are specified to minimize potential health effects arising from ingestion of these anions in drinking water [1]. Other common anions, such as chloride and sulfate, are considered secondary contaminants, and are regulated under the U.S. Secondary Drinking Water Standards, which are guidelines regarding taste, odor, color and certain non-aesthetic effects [2]. In addition, the discharge of these inorganic anions is regulated under the Clean Water Act, which has the goal of reducing the discharge of pollutants into U.S. waters.
