Abstract

Phenol from the wastewater can be removed by various techniques including biodegradation, photo decomposition and adsorption. This paper presents review on phenol removal by adsorption by using various adsorbents. The present review aims at presenting the research on phenol adsorption, findings and effectiveness of the adsorbents in phenol removal. Effects of various parameters like adsorbent dose, pH, particle size on rate of adsorption have been studied by various researchers. Also optimum values of these parameters have been reported. The investigation carried out indicates that there is wide scope for use of low cost adsorbents. The isotherm studies carried out by investigators are reported and it was observed that the uptake of phenol follows the Langmuir and/or Freundlich isotherm in most of the cases. Regeneration and reuse of the adsorbent is the key area of research. The development of efficient method for regeneration and recovery will make the adsorption, a more economical and atrractive option for phenol removal.
