ASTM D3867

Nitrite-Nitrate in Water

Applicability: ASTM D3867 is applicable to the determination of nitrite, nitrate, and combined nitrite-nitrate nitrogen in various water types, including surface water, saline water, wastewater, and ground water. It is a standard test method that can be used for a range of concentrations from 0.05 to 1.0 mg/L of nitrogen, with the potential to be extended beyond this range by diluting samples.

Purpose: The purpose of ASTM D3867 is to provide standard test methods for determining the concentration of nitrite-nitrogen, nitrate-nitrogen, and combined nitrite-nitrate nitrogen in water and wastewater. These methods are used to test water quality, monitor environmental compliance, and ensure the safety of drinking water by measuring these key components, often using the automated or manual cadmium reduction method.
