Preparation and Application of Chitosan Supported Nano Titanium Dioxide
Because of its strong polarity and easy aggregation of nano-titanium dioxide,its excellent properties can not be played fully,which seriously affects its application,and various modifications of nano-titanium dioxide have become the research hotspot of nanomaterials science.In this paper,the polymer material of chitosan supported nano-titanium dioxide was prepared,and its photocatalytic performance in the degradation of phenol in wastewater was studied.The conclusion was drawn that the best effect is achieved when the pH of the solution is 7～8,the amount of catalyst is 0.3～0.4 g/L and the oxygen flow rate is 1.5 L/min.
