Overall adsorption rate was compared to investigate the adsorption characteristics of dye acid-blue 92 with pH and temperature, where was performed by a differential bed reactor with TiO2 of 3.3 g. Overall adsorption rate of a dye acid-blue 92 on titanium dioxide was described as following equation.
r=k1Ce9.4-k2qe5.4
In the range from pH 2 to pH 12, value of klof the dye acid-blue 92 decreased from 0.84 to 0.05 but k2 increased from 0.08 to 0.39 with an increasing pH. Removal rate of a dye was described as an apparent first order and rate constant as the highest at pH 2 and decreased with an increasing pH. With an increasing temperature from 20 to 50 ˚C. both values of kl and k2 increased from 0.75 to 0.97 and from 0.10 to 0.15, respectively. and removal rate constant, k, increased, too.
