Preconcentration Methods in Atomic Spectrometry
Definitions. Control of contamination and loss. Flow injection analysis,(FIA). Hydride generation. Liquid-liquid extraction. Precipitation and coprecipitation. Sorbent extraction: Sorption of metal-chelates on nonpolar sorbents and retention of metal ions by chelating agent adsorbed on a support. Enrichment by ion-exchange, chelating exchange. Hyphenated techniques: Joint separation techniques (HPLC, GC, capillary GC, capillary electrophoresis – CE) with Atomspectrometric detectors (ICP-AES, ICP-MS, GFAAS, FAAS etc.). Field flow fractionation (FFF): separation and preconcentration. Competency: critical approach of publications; design, realization and evaluation of a preconcentration procedure.
The slides of the lecture are available for the students in electronic form.
