The Photocatalytic Reduction of TiO2 on Hg(Ⅱ)
-
Abstract
TiO2 powder photocatalyst was prepared by using sol-gel method.Its photocatalytic reduction efficiency on Hg(Ⅱ) solute was investigated.The results demonstrated that photocatalytic reduction efficiency was highest when TiO2=2g/L,Hg(Ⅱ)ini=7μg/mL.The reduction efficiency was greatly promoted when N2 was blown,when anatase TiO2 was regarded as photocatalyst.
