Abstract: Bamboo charcoal, TiO₂ and light were combinated as a synergistic system of adsorption-catalysis-photooxidation, and the characteristic of phenol degradation by this system was investigated.The effects of amount and granularity of bamboo charcoal, pH value and initial concentration of phenol on removal of phenol were discussed. The results show that the effect of photooxidation is the optimum when the amount of bamboo charcoal is 1 g/L. The smaller granularity of bamboo charcoal is, the worse is degradation of phenol. Granularities of 0.520-0.246 mm are appropriate.Acidity is propitious to degrade phenol, and when pH value is 3 the degradation effect is the best.Increase of initial concentration of phenol results in the decrease of degradation, but increase of average reaction speed.

Key words: bamboo charcoal, TiO₂, photocatalysis, photooxidation, phenol
