NEDA法测定水质苯胺类对pH调节方法的改进

NEDA Method Determination of Aniline Water Quality Improvement of pH Adjustment Method

介绍了NEDA法反应机理、pH调节方法对实验结果的影响,pH控制范围及其改进pH调节方法,叙述了合理控制把固体硫酸氢钾配制成液体硫酸氢钾溶液的保存时间,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、生态等相关领域应用。

The reaction mechanism of NEDA was introduced, the influence of pH, and the adjustment method of pH, and the results of the experiment control and the method of pH adjustment were introduced and the reasonable control of the solid potassium hydrogen sulfate, save time, the biggest, the sensitivity of the optimal analysis the effect and the ideal experiment method were described. The method was available in chemical industry, textile, dye, ecology, and related applications.
