Adsorption of o-Cresol from Its Aqueous Solution on Granular Activated Carbon Columns

Abstract

Compliance with stringent discharge limits and the most
economic way of achieving it without loss of production has led to
continued refinement of existing treatment technologies and the
recognition and development of promising emergent technologies.
Adsorption on granular activated carbon (GAC) has proved itself
as an efficient technology for removal of final traces of a broad
spectrum of toxic organic compounds from domestic and industrial
wastewaters. In the present investigation, experiments have been
carried out to determine the effect of various physico'-chemical
parameters associated with both adsorbent and adsorbate on the
adsorption of o-ctesol from aqueous phase. Some design parameters
such as bed height,. adsorbate flow rate, temperature, initial adsorbate
concentration and adsorbate pH for efficient designing of fixed
bed GAC columns has also been investigated. The commercially
available bituminous coal based granular activated carbon
Filtrasorb-300 (F 300) was used as adsorbent. The validity of the
Michael's mass tranfer zone (MTZ) concept for designing adsorption
columns was used in this work.
