The influence of β-cyclodextrin(β-CD) on the photocatalytic decolorization of methyl orange solution under ultraviolet irradiation was studied by UV-Vis spectral analysis.The photocatalytic decolorization rate of the methyl orange solution was found to decrease with the addition of β-CD.The suppression of the methyl orange decolorization by β-CD was significant at pH 610,and maximized at pH=8.At 3 h irradiation,the decolorization rate of a 5×10^-5 mol/L methyl orange solution containing 4×10^-4 mol/L β-CD was 3/5 that of a blank methyl orange solution.
