Collaborative Study of EPA Method 317.0 for the Determination of Inorganic Oxyhalide Disinfection By-Products in Drinking Water Using Iion Chromatography with the Addition of a Postcolumn Reagent for Trace Bromate Analysis

摘要

The development of the U.S. Environmental Protection Agency (EPA) Method 317.0 is initiated to provide a sufficiently sensitive and fundamental technique for the compliance monitoring of trace levels of bromate in drinking water. After a comparative evaluation of Method 317.0 and elimination of a chlorite interference, this method is tested by a collaborative study in order to determine the precision and bias of the method and evaluate its potential role as a future complicance-monitoring method for inorganic disinfection by-products (DBPs) and trace bromate. This technique provides a practical method for future compliance monitoring for all of the inorganic oxyhalide DBPs trace concentrations of bromate.
