Treatment of phenol-containing aqueous solutions by membrane-based solvent extraction in coupled ultrafiltration modules

Batch adsorption of phenol onto physiochemical-activated coconut shell

“…In fact, phenol has been classified as a scheduled waste in Malaysia where a stringent disposal standard is a must; the content of phenol in wastewater must not be greater than 0.001 mg l −1 for standard A effluent and 1.0 mg l −1 for standard B effluent [4]. Several ways have been developed to remove phenol from wastewater, including electrochemical oxidation, chemical coagulation, solvent extraction, membrane separation, and photocatalytic degradation [5][6][7][8][9]. Yet, still the adsorption technique using activated carbon is the most favorable method due to its efficiency; high adsorption capacity and low operational cost method.…”

Adsorption equilibrium of phenol onto chemically modified activated carbon F400

“…In appropriate circumstances, the phenolic compounds contained in these wastes can be economically recovered, but usually the best method to treat these wastes is their destruction by chemical oxidation techniques [1][2][3] or by adsorption followed by regeneration of the adsorbent [4][5][6][7][8][9]. Other techniques that have been studied for this treatment include electrochemical oxidation [10], chemical coagulation [11,12], solvent extraction [13], membrane techniques [14], and combined methods [15,16].…”

A combined photolytic–electrolytic system for the simultaneous recovery of copper and degradation of phenol or 4-chlorophenol in mixed solutions

“…The efficiencies of processes designed to recover phenols from, or to mineralise phenols in aqueous media have been described (Kulkarni and Dixit, 1991;Garcia-Mendieta et al, 2003;Lazarova and Boyadzhieva, 2004). Activated carbon adsorption and solvent extraction processes have been used in processes of phenol recovery, while biological and chemical oxidation treatment methods have been conventionally preferred for the destruction of this type of organic compound.…”
