Test Method:
Zinc reduction method
Reference: ASTM D 3867-09, Nitrate Nitrite in Water, Test Method B. APHA Standard Method, 23rd edition, Method 4500-N03-E-2016. USEPA Methods for Chemical Analysis of Water and Waste, Method 353.3 (1983). Nelson, JL, Kurtz, LT, and RH Bray, rapid determination of nitrate and nitrite. Analytical chemistry, V26，p。 1081-1082， （1954）。
Use zinc as a reducing agent to reduce nitrate to nitrite. Then, the nitrite concentration was determined by colorimetric method. This method is applicable to industrial wastewater, drinking water, and surface water. These nitrate testing kits in water can also be used for seawater analysis. This method will measure nitrate in the presence of low levels of nitrite (through differentiation). The results are expressed in ppm (mg/L) NO ∝⁻ - N.
