K-6973 nitrate reagent is used in conjunction with V-2000/V-3000 portable multi item water quality meter or 13mm diameter spectrophotometer to determine the nitrate content in water. Test range: 0-1.50 ppm.
Product Details
Nitrate reagent
K-6973 nitrate reagent is used to test the content of nitrate in water. For example: freshwater, seawater, and industrial water.
This kit requires the use of a CHEMetrics direct reading spectrophotometer (multi parameter water quality analyzer: V-2000/V-3000) or a 13mm circular colorimetric dish spectrophotometer.

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.
