Abstract

Abstract: A series of ionic liquids was synthesized from phosphotungstic acid and alkyl substituted quaternary phosphonium salts with different molar ratios, and characterized by DSC and IR. The results show that [P(C14H29)(C6H13)3]-phosphotungstic series ionic liquids are liquid at room temperature. The degradation of Rhodamine-B(RhB) dye was successfully achieved by different phosphotungstic quaternary phosphonium ionic liquids under visible light irradiation. The degradation efficiency was characterized by decolorization and chemical oxygen demand(COD) of RhB. The influence of experimental parameters, such as the carbon chain length in the phosphonium ionic liquid, dosage of catalysts, irradiation time and the concentration of RhB solution on photo-catalyzed degradation of RhB were investigated. The results indicate that [P(C14H29)(C6H13)3]3[PW12O40] ionic liquid shows the best photo-catalytic degradation effect under visible light irradiation. The degradation rate can be up to 95% when the catalyst dosage is 0.3 g and concentration of RhB is 8.35×10-5 mol/L(50 mL) in 3 h. The decolorization of [P(C14H29)(C6H13)3]3-PW12O40 can reach 97% even used for 5 times.

Key words: room-temperature ionic liquid, phosphotungstic acid, quaternary phosphonium salts, Rhodamine-B, photocatalytic degradation
