测定苯胺类化合物pH控制范围及调节方法的研究

Study on pH control range of aniline compound measured by NEDA method and its regulating method

介绍了 NEDA法反应机理及其酸度、p H调节方法对实验结果的影响 ,叙述了合理调整 p H控制范围及改进 p H调节方法 ,可以得到最大灵敏度、最佳分析效果及理想的实验方法。该方法可在化工、纺织、染料、生态。

In this paper, the effect of acidity and pH regulating method on the result of experiment in NEDA method was introduced and how to obtain max sensitivity,optimum result of analysis and ideal method of experiment by reasonably regulating pH control range and improving its regulating method was described. The practical results of many years show that this method can be widely used for chemical, textile, dyestuff, ecological and environmental protection areas etc.
