Ion Chromatography in Environmental Analysis

Environmental analysis is one of the most important fields of application in ion chromatography it is divided into water-, soil-, and air hygiene. [Pg.588]

The main focus of applications in environmental analytical chemistry is the qualitative and quantitative analysis of anions and cations in all kinds of water [3-8]. For example, the concentration of the anions chloride, nitrite, bromide, nitrate, orthophosphate, and sulfate in water determines its quality. Using ion chromatography, these anions can aU be separated and determined in less than ten minutes. The high sensitivity of this method (detection limit with a direct injection of 50 pL sample 10 pg/L) and the potential for automation were two [Pg.588]

Amperometry Oxidation or reduction on Ag-/Pt-/Au-/Glassy Carbon-and Carbon Paste electrodes Anions and cations with pfQ, or pfC 7 [Pg.589]

UV/Vis detection with or without post-column derivatization UV/Vis light absorption UV-active anions and cations, transition metals after reaction with PAR, aluminum after reaction with Tiron, lanthanides after reaction with Arsenazo I, polyvalent anions after reaction with iron(III), silicate and orthophosphate after reaction with molybdate [Pg.589]

Charge Response to ionic species by drawing a current to a fixed potential Weakly dissociated anions and cations [Pg.977]

Fluorescence in combination with postcolumn derivatization Excitation and emission Ammonium, amino acids, and primary amines after reaction with OPA [Pg.977]
