Aside from HPLC and GC, capillary electrophoresis (CE) is one of the most important techniques for high-performance separations in modern analytical chemistry. Its main advantages are the possibility of using different detection techniques, the possibility of in-capillary sample processing for preconcentration or derivatization, and ease of instrumental miniaturization down to the microfluidic scale. Those features are utilized in the separation of macromolecules in biochemistry and in genetic investigations, but they can be also used in determinations of inorganic ions in water analysis. This review, based on about 100 original research works, presents applications of CE methods in water analysis reported in recent decade, mostly regarding conductivity detection or indirect UV detection. The developed applications include analysis of high salinity sea waters, as well as analysis of other surface waters and drinking waters.

除了高效液相色谱法和气相色谱法外，毛细管电泳（CE）也是现代分析化学中最重要的高效分离技术之一。它的主要优点是可以使用不同的检测技术，能够在毛细管内进行样品预处理，如浓缩或衍生化，并且易于将仪器微型化到微流控尺度。这些特点在生物化学和遗传研究中的大分子分离中得到了应用，但也可以用于水中无机离子的测定。本综述基于约 100 篇原始研究工作，介绍了近十年来 CE 方法在水分析中的应用，主要涉及电导率检测或间接紫外检测。所开发的应用包括高盐度海水分析，以及其他地表水和饮用水分析。
