离子色谱法测定硝酸盐氮研究

Study on Determination of Nitrate Nitrogen by Ion Chromatography

文章探讨了一种测定地表水和饮用水中硝酸盐氮的直接方法——离子色谱法。与常用的酚二磺酸比色法相比,该方法具有简便、安全的优点,干扰少、准确度高。

A direct method of determining nitrate nitrogen in ground water and drinking water has been studied. This method has several advantages: manipulation is simple and safe, and less interference in comparison with phenol disulfonic acid method.
