Abstract

Phaeocystis globosa is harmful algae species, which booms along the coast of China frequently during recent years. In order to find a simple, effective and safe method to remove P. globosa, research was carried out using nano-TiO2 or Fe3+-droped nano-TiO2 thin film to remove P. globosa under visible light. The authors find that Fe3+-droped nano-TiO2 is more effective in removing P. globosa than nano-TiO2. After using 20mg·L-1 Fe3+-droped nano-TiO2 for 48 h visible light treatment, the algal density reduced to 0.01×104cell·mL-1 from 4.08×104cell·mL-1, and the consistency of Chl-a reduced to 0.001mg·L-1 from 0.43mg·L-1, namely more than 99.7% cells were removed. The dynamics of algal removal follows the first order reaction.

Key words： Fe3+; TiO2 thin film; visible light; Phaeocystis globosa
