Effect of Binder on Physical Properties of Extruded Activated Carbon and Its Application to Levofloxacin Adsorption

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Bamboo charcoal–based extruded activated carbons were prepared via molding, pre‐oxidation, carbonization, and steam activation, with coal tar, phenolic resin, and their mixtures employed as binders based on practical availability and technical feasibility. This study focused on the regulatory effects of binders on the mechanical properties and
