Abstract

The Chromatographic retention and separation of NO 2 - , Br-, NO 3 - , and I- anions on a column packed with Nucleosil 100-5 C18 dynamically modified with trimethyloctadecylammonium bromide (TMODAB) was studied using direct UV detection. A procedure was developed for the determination of the above anions in the concentration range 0.06-2500 Μg/L without preconcentration. Sample preparation involved only the elimination of organic impurities (if present) from the test sample. The procedure was used for the determination of NO 2 - and NO 3 - anions in Baikal Lake water and in an aerosol extract.
