Abstract

Phenol and phenolic compounds are the common water pollutants in the effluents from various industries and even in the small amounts are undesirable for human health. In this research work adsorption of phenol on the activated carbon prepared from thermal degradation of industrial waste lignin was studied. The industrial waste lignin was subjected to thermal degradation at temperature of 5000C in N2 atmosphere in presence of ZnCl2 catalyst. The major product obtained after degradation is the activated carbon. The activated carbon obtained was characterized with proximate analysis, CHN analysis, FTIR, SEM and surface textural properties. The surface morphology of the AC reveals that it posses high porosity and surface area, hence it can be utilized for adsorption purpose. The adsorption capacity of the prepared AC for phenol was studied with various parameters such as effect of contact time, adsorbent dose, pH and initial concentration. The maximum adsorption for phenol is found to be 19.3050mg/g. To describe the equilibrium isotherms, Langmuir and Freundlich models were applied. Although adsorption equilibrium data was found to follow Freundlich model, it was better fitted in Langmuir model. The scope of this work suggests that the AC obtained from industrial waste lignin can be utilized as a low cost adsorbent for the removal of phenol from aqueous solution.
