БИОСЕНСОР ДЛЯ ОПРЕДЕЛЕНИЯ ПАРОВ ФЕНОЛА В ВОЗДУХЕ

摘要

FIELD: analytical chemistry of organic compounds; detection of phenol vapors contained in air of working zone. ^ SUBSTANCE: proposed method of production of biosensor includes preparation of modifier and application of it on strain sensitive area of piezo-resonator. For preparation of modifier, use is made of Triton X-100 mixture and extract of micella of Pleurotus ostreatus at volumetric ratio of 1:1; total mass of sorbent is 10-15 mkg; mass of batch of Pleurotus astreatus is 8-10 g; used as solvent and extractant is acetone. ^ EFFECT: enhanced sensitivity of biosensor to phenol vapors. ^ 1 dwg, 3 tbl, 4 ex
