FIELD: organic chemistry, analytical chemistry.
SUBSTANCE: method involves photometric determination of 2-naphthol after its preliminary elution from a column filled with polyurethane foam as a sorbent impregnated with mixture hexanol-diethyl phthalate in their mass ratio 70-75% and 25-30%, respectively. Method provides enhancing selectivity of assay and accelerating analysis carrying out. Invention can be recommended for analysis of treated sewage.
EFFECT: improved assay method.
