An analysis is described for the rapid determination of nitrate-N in plant extracts. The complex formed by nitration of salicylic acid under highly acidic conditions absorbs maximally at 410 nm in basic (pH>12) solutions. Absorbance of the chromophore is directly proportional to the amount of nitrate-N present. Ammonium, nitrite, and chloride ions do not interfere. |
