| Abstract | ||
| Abstract The effects of non- porous powder samples of TiO2 (with specific surface areas of about 55 m2g-l) on the kinetics of disappearance of 2,4,5¬Trichlorophenol (2,4,5- TCP) in water were determined. The photocatalytic character of the 2,4,5- TCP disappearance in its presence was shown by (i) the effects of the catalyst mass on the initial rate ro, (ii) the Langmuirian -type relationship between ro and Co (iii) the low activation energy of 2,4,5- TCP disappearance (iV) the effect of pH solution, (V) the effect of initial concentration Co of 2,4,5- TCP on the rate of photodegradation ro by using medium pressure mercury lamp at 125 W. | ||
