Abstract:Indoor air pollution is the mainsource thatafects human health,which isalsothekeyresearch point in “Towards People's Life and Health”.Inorder to achieve passvely fast and enduring purification of indoorair with selecting purification schemes based on diferent scenes,it is necessary to clarify micro/mesoscopic adsorption mechanisms of indoor gaseous pollutants and develop corresponding technology systems.In this review,two adsorption mechanisms are summarized and analyzed,and3adsorption purification technologies are compared for common indoor gaseous polltants:1)Adsorption mechanisms.“Physical/Chemical Adsorption”mechanism can be used to capturemany pollutantsforlong time but its capture capacities are limited with large possibilities ofrereleasing.“Catalytic Oxidation/Reduction Adsorption” mechanism is good at achieving oriented purification with nontoxic products,while itsapplication conditionsare harsh andcan only last for short times.2)Adsorption technologies.“Negative-pressre Filtration Adsorption Technology”is based on the mechanism of“Physical/Chemical Adsorption”,and itsadvantages are relatively high capture rates/multiple appicable scenes with disadvantages of limited spatial purification scopes/production of secondary polutants.“Catalytic Adsorptive Purification Technology”stems from the“Catalytic Oxidation/Reduction Adsorption”mechanism,which canquickly,efciently and harmlessly convert pollutants into green products via catalytic processs under specific scenes.However,current commercialphotocatalyticair-purification devicesarelowinpurification eficiencies.“PhytoremediationPurification Technology”works through biological absorption/metabolism ofplants/microbes on indoorgaseous polltants.This technologycouldachieve enduring andgreen purification for long timewith almost no hazardous products.But its purification rates arelow and cultivation costs are high. With analyzing and comparing features of different adsorption mechanisms and technologies,a combined usage of several mechanisms/technologies is finally discussed to enhance capture abilities of common gaseous polltants under different indoor scenes.
