Title:AdsorptionofPhenolfromWastewaterbyCross-linkedModifiedChitosan:AResearchStudy
Abstract:
Environmentalpollutioncausedbyphenol-containingwastewaterhasbecomeamajorconcernduetoitstoxicityandadverseeffectsonecosystems.Adsorptioniswidelyrecognizedasaneffectiveandeconomicalmethodforremovingphenolfromwastewater.Thisstudyfocusesontheutilizationofcross-linkedmodifiedchitosanasanadsorbentforphenolremoval.Theresearchaimstoexploretheeffectivenessoftheadsorbentinadsorbingphenolandinvestigatetheinfluencingfactors,suchaspH,initialphenolconcentration,contacttime,andadsorbentdosage.Thestudyalsodiscussestheadsorptionmechanismandevaluatestheregenerationandreusabilityoftheadsorbent.Thefindingsofthisresearchprovideinsightsintothepotentialapplicationofcross-linkedmodifiedchitosanasasustainablesolutionforphenolremovalfromwastewater.
