摘要

A growing demand for efficient air quality management calls for the development of echnologies capable of meeting the stringent requirements now being applied in areas of chemical,biological and medical activities.Currently,filtration is the most effective process available for removal of the fine particles from carrier gases.Purification of gaseous pollutants is associated with adsorption,absorption and incineration.In this paper we discuss a new technique for highly efficient simultaneous purfication of gaseous and particulate pollutants fromcarrier gases,and investigate the utilization of porous media.Our technique involves the passage of contaminated carrier gases through a porous medium submerged into a liquid,leading to the formationof narrow and tortuous pathways through the medium.The wet walls of these pathways result in outstanding purification of gaseous,liquid and solid alien additives.NMR imaging was successfully used tomap the gas pathways inside the porous medium submerged into the liquid alyer.
