Scope
This document specifies the principles, reagents and materials, instruments and equipment, samples, analysis steps, result calculation, precision and accuracy, quality assurance, and quality control for the determination of alkalinity, carbonate, and bicarbonate concentrations in water by automatic potentiometric titration. This document is applicable to the determination of total alkalinity, carbonate alkalinity, bicarbonate alkalinity, and carbonate and bicarbonate concentrations in surface water, groundwater, atmospheric precipitation, and domestic drinking water. It can also be used as a reference for the determination of these parameters in domestic sewage and industrial wastewater.
