<p>The aim is to provide a liquid absorbent for volatile organic compound removal that has a high absorption ratio of VOCs in exhaust and is capable of simultaneously removing isolated acids by means of hydrolyzing esters in VOCs, and to provide a purifying method for exhaust VOCs using said absorbent. Disclosed are an absorbent that comprises an epoxy compound and is liquid in a normal state, a purifying method for VOC-containing exhaust using said absorbent, and a recovery method for VOCs and the absorbent. The epoxy compound is an organic compound that has an epoxy group in each molecule, and the epoxy compound that is optimal as an absorbent for removing VOCs in exhaust has a molecular weight of at least 250 and a boiling point of at least 200°C. The absorbent comprising the epoxy compound is capable of simultaneously absorbing VOCs and removing isolated acids.</p> |
