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 dry decomposition of plant materials in APION 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 Cr, Mo, and Ni content calculated by test organizers as true values. Since quality of Ti data given by IPE organizers is insufficient to be used for evaluation with Z-score attempt, Ti data determined after evaporation of ash with HF as total contents were used for the evaluation of the efficiency of ash dissolution. Risk of analyte losses by the retention in insoluble residues from decomposition of plant samples by modified dry ashing in APION at 400 centigrades increase in order Cr =~ Mo < Ni < Ti.
