find a method for recovering organic solvents free of pollutants
[17].
Cooney et al. studied the desorption of a representative organic
adsorbate (phenol) from activated carbon using nineteen solvents
in batch tests. Three of the better solvents, which also possessed
complete miscibility with water (acetone, dimethylformamide, and
methanol), were tested further in fixed-bed runs [9]. In addition,
Zhang et al. studied the influence of activated carbon regeneration
on the treatment of dyed house wastes using an organic solvent
[18]. However, studies of the regeneration of activated carbon in
coking wastewater advanced treatments using low boiling point
organic solvents and surfactant solutions have not been reported
