Abstract

Abstract: A solid photocatalyst of Keggin-type Cr(Ⅲ) substituted heteropolytungstates immobilized on the surface of alkalescent anionic exchange resin D301R(PW11Cr/D301R) was prepared. Its visible light photocatalytic activity was assessed through the degradation of a model pollutant rhodamine B(RhB). The photocatalysis mechanism was discussed and influences of the PW11Cr/D301R dosage, the solution pH and the common anions existing in solution on the photocatalytic degradation rate of RhB were also examined. The time required to achieve a complete degradation of RhB is only 30 min in the presence of 100 mg PW11Cr/D301R when a solution containing 10 μmol/L RhB is exposed to irradiation of the 200 W metal halide lamp. This process is three times faster than that in the PW11Cr homogeneous system. Approximate 84% of the total organic carbon(TOC) removal is reached at 180 min. The PW11Cr/D301R dosage, the solution pH, and existing anion such as Cl-, SO2-4 or PO3-4 all have an obvious influence on the photocatalytic degradation rate of RhB. There is no obvious lost of photocatalytic activity of PW11Cr/D301R after seven repetitive uses.

Key words: Cr(Ⅲ)-substituted heteropolyanion, visible photocatalyst, rhodamine B degradation, total organic carbon, D301R resin
