o-Nitrophenol, m-nitrophenol, and p-nitrophenol could well be separated by capillary zone electrophoresis (CZE) by only adjusting the run buffer with methanol. Efficiency up to 10(5) theoretical plates per meter was achieved. The effects of several important factors were investigated to find optimum conditions. The linear range, regression equation, and the recovery were given. This method possessed the advantages of simplicity, rapidity, and good reproducibility; it can be developed for the separation of practical samples in environment analysis.
邻硝基苯酚、间硝基苯酚和对硝基苯酚仅通过用甲醇调节运行缓冲液，就可以很好地通过毛细管区带电泳（CZE）进行分离。实现了高达每米10⁵理论塔板数的效率。研究了几个重要因素的影响以找到最佳条件。给出了线性范围、回归方程和回收率。该方法具有简单、快速和重现性好的优点；可用于环境分析中实际样品的分离。
