Equilibrium and kinetic studies on removal of phenolic compounds using activated carbon coated monolith

Activated carbon coated monolith (ACCM) was prepared by dipcoating method using a polymer mixture (furfuryl alcohol, and poly ethylene glycol). The adsorptive performance of phenol, 4-chlorophenol (4-CP), 2,4-dichlorophenol (2,4-DCP) onto the ACCM was comparatively evaluated by batch mode. Experime...

The equilibrium adsorption capacity were increased 50.3 -62.9 mg/g (phenol), 88.9 - 111.5 mg/g (4-CP), and 89.9 - 117.5 mg/g (2,4-DCP),respectively at an increasing initial concentration of 400 – 600 mg/L.
