The integration of adsorption and photocatalysis process is considered to have a better prospect inhandling of organic wastes. The combination of catalyst consisting of Ti0; photocatalyst and activecarbon (AC) adsorbent has been evaluated to treat a phenol waste. Preparation of catalyst wasconducted by evaporating all dilution of TiO; slurry, which has been mired with the granular of activecarbon at a temperature of l00"C and calcined at a temperature of 400"C. SiO; which obtained fromTEOS solutions was added to prevent a falling off TiO;]rom AC support Characterization of BET wasconducted to find out the surf/'ace area as well as pore size of the catalyst. Activity test of the catalystmaterial was done by conducting of 30 ppm phenol solution in annular Pyrex glass reactor thatsurrounded by 3 U V lamps, which have the total illumination intensity of I 44 ,UW/ml. The phenol solutionwas continuously poured in the reactor with rate of 35 ml/min for about 8 hours. The phenolconcentration was analyzed with spectrophotometer at wavelength of500 nm. The optimum condition ofthis domination was reached by using a catalyst of Ti0/SiO;/AC with composition of 2.4:0.047:97.5(weight ratio), and succeeded in eliminating of 30 ppm phenol with 100 % conversion. |
