Using sorption method of Acid Retardation in the systems composed of two liquid phases, to address the problems of sample preparation in ICP-MS elemental analysis
The results of studies are presented for testing new approach to the Acid Retardation method in which the separation of electrolyte mixes is realized at using columns with anion-exchanging beds filled with organic liquids immiscible with water and aqueous solutions. Component separation for natural solution of the digestion of, on soil on the anion exchanger AV-17 in the nitrate form show the proposed approach to be promising for sample preparation in elemental analysis, in particular, for efficient reduce of the acidity of solutions produced at the decomposition of hardly decomposed materials.
