FIELD: chemistry.
SUBSTANCE: disclosed is a method which includes soaking a hydrophobic polymer sorbent with a salt solution in a polar organic solvent. The used salt has solubility in methanol of not less than 1 mol/l and is selected from copper, zinc, cobalt and iron chloride or magnesium perchlorate.
EFFECT: invention enables to obtain a sorbent for quantitative analysis, having a low detection threshold for the determined substances.
