摘要：

The system ergonovine maleate-p-diethylaminobenzaldehyde in sulfuric acid media is applied to the kinetic-spectrophotometric determination of nitrite ions with competitive precision. The reaction rate is strongly enhanced by the presence of nitrite or ferric ions, being the nitrite in the promoting" role of the reaction. Linear calibration plots are obtained for nitrite concentration ranges 0.3-2.4 ppm or 0.66-6 ppb. The influence of foreign compounds is also established. © 1991."
