Abstract	TiO$_{2}$ was prepared by a hydrothermal method. It was chemically combined with carboxymethyl cellulose prepared from biodegradable ramie fiber to obtain the TiO$_{2}$/ramie fiber composite. The TiO$_{2}$/ramie fiber composites were characterized by an X-ray diffractometer, an environmental scanning electron microscope, and a Fourier-transform infrared spectra. The results indicate that TiO$_{2}$ is chemically combined with ramie fiber, and it can be reused more than five times without obvious TiO$_{2}$ loss. The photocatalytic performances of TiO$_{2}$ and TiO$_{2}$/ramie fiber composite used to degrade both a methyl orange (MO) anionic dye and a rhodamine B (RB) cationic dye solution indicate that the photocatalytic activities of TiO$_{2}$ for the degradation of the above described solutions are greatly improved when the TiO$_{2}$ is dispersed on ramie fiber. When 0.5 g of the TiO$_{2}$/ramie fiber composite is added to a dye solution for 3 h, the degradation rates for the initial concentrations (20 mg/L of MO and 12 mg/L of RB) are greater than 90 %. The photocatalytic degradation of MO can be described as a zeroth order reaction.
