Removal of bromophenols from water using industrial wastes as low cost adsorbents

Phenolic compounds biosorption onto Schizophyllum commune fungus: FTIR analysis, kinetics and adsorption isotherms modeling

“…Thawornchaisit and Pakulanon determined that the sorption equilibrium of phenol on dried sewage sludge was reached within 20 h [47]. Adsorption of bromophenols onto carbonaceous adsorbents derived from fertilizer solid waste was performed by Bhatnagar [54] and reported an equilibrium time of about 8 h. …”

Process development for the batch and bulk removal and recovery of a hazardous, water-soluble azo dye (Metanil Yellow) by adsorption over waste materials (Bottom Ash and De-Oiled Soya)

“…The column adsorption studies were undertaken to understand the practical utility of adsorption process. Bulk removal of the adsorbate by column studies proves to be more advantageous over batch studies as the exhaustion capacity of column is usually found to be relatively higher than the batch capacity [54]. This is because of establishment of continuous larger concentration gradient at the interface zone as the influent passes through the column.…”

Batch adsorption of phenol onto physiochemical-activated coconut shell

“…Excessive presence of phenol and its derivatives in natural water sources is considered as a serious threat to human health and overall water quality [1]. Phenolic compounds are very harmful to organisms even at low concentrations due to its toxicity and carcinogenicity properties.…”
