QUANTITATIVE BIOREGENERATION OF GRANULAR ACTIVATED CARBON LOADED WITH PHENOL AND 2, 4- DICHLOROPHENOL

摘要

Lignite based granular activated carbon of 20 ×30 mesh size was used to investigate the extent of bioregeneration of phenol and 2, 4-DCP in a batch system. The adsorption isotherm fits very well with the Freundlich isotherm and it is apparent that 2, 4-DCP is more absorbable than phenol. The degree of reversible adsorption for phenol and 2, 4-DCP were 32.9 and 10.6 /100, respectively.
