Determination of UV-absorbing anions in environmental samples by microcolumn high-performance liquid chromatography

The Chromatographic retention and separation of NO2-, Br-, NO3-, 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...

Description
Summary:The Chromatographic retention and separation of NO2-, Br-, NO3-, 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 NO2- and NO3- anions in Baikal Lake water and in an aerosol extract.
