摘要：

A rapid, sensitive and maintenance-free method for the determination of nitrate ion using the photo-induced conversion of nitrate to nitrite is described. A flow-injection system, equipped with a spectrophotometric detector and a UV irradiation coil cell in which nitrate ion was reduced to nitrite ion, was developed and tested for river and sea waters. With this flow system, the signal intensity depended strongly on the pH of the carrier solution. The detection limit for nitrate was ca. 0.05 muM and ten samples could be determined per hour. The method permitted the determination of nitrate without a copperized cadmium column.
