Study on the Determination of NO_3^- Content by Fingerprint Technology

近年来化学振荡作为一种典型的非线性非平衡现象,引起了广大科研工作者的关注和研究。本文主要研究了利用硫酸-丙二酸-硫酸铈铵-溴酸钠化学振荡体系的特征参数测定水中NO_3^-的浓度。通过正交实验得出最佳实验条件:温度40℃、硫酸(1.0mol/L):25ml、丙二酸(1.25mo/L):8ml、硫酸铈铵(0.1mol/L):2ml、溴酸钠(0.8mol/L):3ml。

As a typical non-linear and non-equilibrium phenomenon,chemical oscillation has attracted much attention and research by the vast number of scientific researchers in recent years.In this paper,the determination of NO3^-content in water by using the characteristic parameters of sulfuric acid-malonic acid-ceric ammonium sulfate-sodium bromate chemical oscillation system was studied.The optimum experimental conditions were obtained by orthogonal experiment:temperature 40℃,sulfuric acid(1.0mol/L):25ml,malonic acid(1.25mo/L):8ml,ammonium ceric sulfate(0.1mol/L):2ml,sodium bromide(0.8mol/L):3ml.
