FIELD: chemistry.
SUBSTANCE: invention relates to chemistry of organic compounds and a method of concentrating resorcinol from aqueous solutions, involving extraction-sorption concentration of resorcinol using a sorbent in form of elastic foamed polyurethane modified with a solution of tributylphosphate in hexane in volume ratio of tributylphophate: hexane equal to 1:(0.5-1) and weight ratio of elastic foamed polyurethane: tributylphosphate equal to 1:(0.5-0.75).
EFFECT: high coefficient of extraction-sorption concentration, increase in degree of extraction to 98,6% and low consumption of tributylphosphate.
