Efficiency of modified dry decomposition for the determination of Cr, Mo, Ni, and Ti in plants

Popis výsledku v původním jazyce

Efficiency of the different media for leaching of selected elements (Cr, Mo, Ni, Ti) from ash obtained by modified decomposition of plant materials in the presence of oxygen, ozone, and nitrous oxides using Dry Mode Mineralizer APION at 400°C has been studied. Plant samples from IPE WEPAL interlaboratory exchange were used in the study. Data obtained for chromium, molybdenum, and nickel were evaluated by z-score classification using their contents calculated by test organizers as true values. Since quality of Ti data given by IPE organizers is sufficient to be used for the evaluation with z-score attempt, Ti results determined after evaporation of ash with HF as total contents were used for evaluation of the efficiency of ash dissolution. Risk of analyte loses by the retention in insoluble residues from decomposition of plant samples increases in the order Cr - Mo - Ni - Ti.
