説明
A method for cadmium-copper reduction, which had been used for sea water, was applied for the determination of nitrate nitrogen in drinking water. This is more accurate, sensitive, and more simple than ordinary methods. The determination method is as follows : One ml of 0.1 M NaCl solution is added to 50 ml of a sample aliquot containing between 0.15 and 100 μg of nitrare nitrogen. After rinsing the cadmiumcopper column with the column washing solution (2mM EDTA·4Na solution), the test solution is passed through the column (column length 12 cm, flow rate 10-20 ml/min). Nitrate is quantitatively reduced to nitrite, and many substances in drinking water do not interfere the reduction. Initial 15 ml of the effluent is discarded and the next 10 ml effluent is collected. Nitrite nitrogen concentration of the effluent is determined by the diazotization method.
