ABSTRACT

Ion chromatography is a single instrumental technique widely used for the sequential determination of many common anions in environmental matrices. Anions, such as –3NO , –2NO , 3-4PO , 2-4SO , 2-3SO , F−, Cl−, Br−, I−, oxyhalides, and many carboxylate ions, may be determined rapidly in a single sequential step. e main advantages of the ion chromatography technique are

e method involves chromatographic separation of water-soluble analytes and the detection of separated ions by a conductivity detector. It can also be used to analyze oxyhalides, such as perchlorate ( –4ClO ) or hypochlorite (ClO−), weak organic acids, metal ions, and alkyl amine. e analytes that can be determined by ion chromatography are listed in Table 11.1.
