Study on the heterogeneous photocatalytic degradation of phenol with magnetic zeolite/chitosan microspheres
摘要
Abstract
The study of new catalytic materials is the most important task to reduce the environmental pollution of phenol wastewater,reduce the dosage of traditional adsorption materials such as zeolite and chitosan in the treatment of phenol,and reduce the experimental cost.The zeolite-chitosan composite beads as the carrier,through the ion exchange method and liquid phase deposition method make Fe3 O4 load on it,which is a photocatalyst for removing water phenol by UV/Fenton test.The experiment investigates the effects of composite catalyst’s dosage,different phenol concentration,pH value,reaction time,H2 O2 quantity,temperature,light strength,different materials catalyze UV/Fenton etc.The experiments show that in concentration phenol wastewater is 20mg/L,pH =6investment plus 0.5g composite catalyst,0.3ml H2O2,reaction 70min during 24W UV light irradiation,the phenol re-moval rate can reach 91 .46%.Under the same conditions,MZC catalyzed the heterogeneous UV/Fenton reaction to treat phenol with the strongest photocatalytic ability. Magnetic zeolite chitosan as photocatalyst has better photocatalytic effect and high phenol removal rate .关键词
