Název v původním jazyce

Analysis of iodine and its species in animal tissues

Popis výsledku v původním jazyce

A method allowing the determination of the total iodine content and iodine species in samples of animal tissues using inductively coupled plasma mass spectrometry (ICP-MS) as an element-specific detector was developed. The total iodine content was determined after microwave digestion with 25% (w/w) water solution of tetramethylammonium hydroxide. The detection limit was 26.9gkg(-1) I, and the accuracy of the determination was proven through the analysis of SRM Non-Fat Milk Powder, porcine liver, and Atlantic Cod muscle samples using standard addition methods. The extracts for the speciation analysis were prepared through sample dispersion in water using an Ultra-Turrax((R)) T10. The extraction yields ranged from 46 to 84% for different types of tissues. The determination of the inorganic iodine species was performed using ion-exchange chromatography (PRP X100, mobile phase 100mmolL(-1) ammonium nitrate, pH 7.4) coupled to ICP-MS. A detection limit of 1.1gkg(-1) I was obtained for both
