Study on the Dispersion of Carbon Doped Titanium Dioxide Powder in Aqueous Solution

Article Preview

Abstract:

The dispersion of carbon doped titanium dioxide (TiO2) powder in aqueous solution was studied. The spectrophotometer method was used to determine the effects of dispersant additive ratio, ultrasonic time and pH value on the dispersion of TiO2. The results show that the carbon doped titanium dioxide aqueous solution was found to have the optimum dispersion performance when the mass ratio of sodium hexametaphosphate (SHMP)/TiO2/water is 1:50:100, the ultrasonic time is 15min and the pH value of the solution is 10.
