Abstract: A method of recovering volatile organic matter such as fuels and organic solvents from a gas or gas mixture containing the organic matter, characterized by subjecting a gas or gas mixture, having diffused thereinto sparingly water-soluble or water-insoluble volatile organic matter in the form of vapor, mist and/or small droplets, to a two-step capturing treatment wherein the gas or gas mixture is first brought into gas-liquid contact with an aqueous capturing system capable of dissolving the volatile organic matter thereby capturing the organic matter in the form dissolved in the aqueous system and then the organic matter-containing aqueous system is brought into liquid-liquid contact with a non-volatile organic liquid, immiscible with the aqueous system such that the organic matter migrates from the aqueous system into the organic liquid, and thereafter recycling the aqueous capturing system to the first step of the two-step capturing treatment, while recovering the volatile organic matters from the non-vola
