Abstract: In order to enhance the integrated utilization of waste cotton fabric, tartaric acid was used to modify the waste cotton fabric through pad-dry-cure process for introducing surface hydroxyl groups, which coordinated with Fe3+ ions to produce the ferric tartrate-modified cotton fabric. Effect of concentrations of tartaric acid and NaH2PO4, as well as curing temperature on hydroxyl groups and Fe content on the surface of ferric tartrate-modified cotton fabric was studied. After characterization by SEM and FTIR, ferric tartrate-modified cotton fabric was evaluated as heterogeneous photo-Fenton catalysts for the oxidative degradation of Acid Red 88. The results indicated that carboxyl groups produced from esterfication between tartaric acid and cotton fiber coordinated with Fe3+ ions to prepare the ferric tartrate-modified cotton fabric. Increasing concentrations of tartaric acid and NaH2PO4 as well as elevation of curing temperature enhanced Fe content on the surface of ferric tartrate-modified cotton fabric. The best modification of cotton fabric was obtained at the condition of 10 wt% tartaric acid and 5 wt% NaH2PO4 as well as curing temperature of 180 ℃. The ferric tartrate-modified cotton fabric could accelerate the dye degradation under light irradiation. Higher Fe content could increase its catalytic activity. Besides, increasing H2O2 concentration favored the dye degradation. The highest degradation efficiency of the dye was obtained when 4.5 mmol·L-1 H2O2 was used at pH=6 with higher temperature. The colorants dyed on the ferric tartrate-mo-dified cotton fabric showed a slight effect on its catalytic performance.
