Ion chromatography as a part of green analytical chemistry

Abstract

Due to the increased environmental awareness, green chemistry becomes an important element of environmental protection. Unfortunately, it generate specific environmental costs, which are related to the use of toxic chemical reagents and waste generation. The most frequently determined analytes include inorganic and organic anions and cations. The methods used so far for their analysis in water, sewage and various other types of samples are increasingly being replaced by ion chromatography methods. This paper presents the most important advantages and limitations of ion chromatography in the context of “green analytical chemistry.” The progress of ion chromatography in gradient and isocratic elution, capillary and multidimensional ion chromatography, as well as miniaturization and methods of sample preparation for analysis, which allow to classify this technique as green analytical chemistry, are described
