A spectrophotometric flow-injection method based on a diazo-coupling reaction is proposed for the simultaneous determination of nitrite and nitrate. Nitrate is reduced to nitrite by using a reductor column which is formed by filling part of the sample loop with copperized cadmium. The flow system pr
