ANION COMPOSITION DETERMINATION OF NATURAL WATERS BY THE METHOD OF ION CHROMATOGRAPHIC

An ion chromatographic method for determination of anion composition of natural waters was described. An automated 850 IC Professional, Metrohm system equipped with conductivity detector after chemical and carbon dioxide suppression was used. The main analytical characteristics were estimated for each of studied analytes. The trueness of the method was estimated by analysis of certified reference material for soft drinking water. Recovery test was performed on spiked drinking water samples. The method was applied for analysis of drinking water before and after chlorination, as well as high mountain lakes. The main directions of development of the ion chromatographic method in the field of applications are summarized. Special attention is paid to high– speed and high– performance chromatography. The analytical capabilities of the ion chromatographic method are compared. It has been shown that in many cases for analytical practice there is no need to use expensive equipment. Chromatography is one of the most promising modern methods in determining product quality. The method is actively used both in production and in laboratories.
