Resumo
Photodegrading dye-contaminated effluents is a promising method for photo energy conversion and utilization. Herein, rhodamine B (RhB) and methylene blue (MB) were used as simulated dye effluent to evaluate the photocatalytic performance of carboxymethylcellulose (CMC-Na) modified SrTiO3 (STO). Cubic aggregated STO was successfully prepared by one-pot hydrothermal method. For the purpose of exploring behavior of dye molecules, different dye concentration ranging from 10 to 30 mg/L and certain catalyst loading were adopted. Under the UV light, group hindrance significantly enhanced the preferential adsorption and photodegradation to MB in RhB–MB binary solution at 10 mg/L. Quantized calculation for dye mixture was achieved. Photodegradation kinetics at different initial concentrations of binary MB/RhB solution followed pseudo-first-order model. Results on residual dye concentration and reaction time were connected by mathematic model, which could be used for predicting the residual amount of organic contaminants in effluent.
