The quality of drinking and irrigation water is based on the level of silicate and borate contents present in it. Therefore, regular analysis of silicate and borate contents is essential, especially in freshwater reclaimed from seawater due to the necessity to control the borate levels.
This application note discusses the application of ion chromatography with direct conductivity detection to determine silicate and borate contents as well as some standard anions present in drinking water.
