PHOTOCATALYTIC DEGRADATION OF RHODAMINE B ON TITANIUM DIOXIDE BONDED ACTIVE CARBON COMPOSITES

UV lamp being lamp house,the photoactivity of the TiO 2 bonded active carbon(TiO 2/AC) was investigated by the degradation of dissoluble Rhodamine B.Moreover,the effects of the pH value,light intensity,temperature in reaction and initial concentration of Rhodamine B in solution on the photocatalytic reaction were discussed.The results indicated that TiO 2/AC shows high photocatalytic activity,the degradation raction of Rhodamine B fits Langmuir Hinshelwood kinetic equation,degradation rate is largely affected by pH value,initial concentration of Rhodamine B and light intensity,slightly for temperature in reaction.In research scope,pH 6 and 40W are good for the degradation reaction of Rhodamine B.
