Zinc chloride-activated glycerine pitch distillate for methylene blue removal-isotherm, kinetics and thermodynamics

This work was aimed at evaluating the adsorptive properties of glycerine pitch distillate-based activated carbons by zinc chloride activation. A commercial activated carbon derived from petroleum pitch distillate was employed for comparison. Activated carbons were characterized for elemental composi...

description This work was aimed at evaluating the adsorptive properties of glycerine pitch distillate-based activated carbons by zinc chloride activation.

The maximum methylene blue capacity of 368 mg/g is comparable with that of commercial activated carbon.
