| Abstract: | The content of chlorophyll,the rates of photosynthesis,photorespiration,superoxide dimutase activity as well as content of O2·- in Cyanobacteria are determined.The inhibitory effects of nano-TiO2 and Pt dopant nano-TiO2 on the growth of Cyanobacteria were studied.The current results have showed,compared with nano-TiO2,Pt/TiO2 was more effective in inhibiting growth of Cyanobacteria under the sunlight.In addition,the current study has shown that 1.5% of Pt dopant nano-TiO2 exhibits the best inhibitory effect on the growth of algae of Cyanobacteria. |
