Elimination of aromatic pollutants present in wastewater by adsorption over zeolites

AbstractPhenol and substituted phenols are toxic organic pollutants commonly present in industrial waste streams especially in industrial wastewater. Water treatment by activated carbon adsorption technique is very advantageous due to their high adsorption capacity and low cost of these materials but it is poorly regenerable In recent years, researchers have focused on class of interesting recyclable adsorbents based on hydrophobic zeolites (Si / Al ratio high) in the field of water treatment. The study on adsorption showed that the affinity of phenol drifts toward the FAU is dependent on the pH solution and on the pollutant solubility in water and finally their economic cost for regeneration after saturation
