Treatment of Phenolic Water Using Adsorption

Abstract

In the present study the adsorbent was prepared from the fruit ’s of Terminalia Chebula obtained from local area of NIT Rourkela. The adsorbent was characterized for
BET surface area, point of zero charge, CHNS, SEM, EDX, FTIR etc. The feasibility of using Terminalia Chebula activated carbon (TCAC) were investigated and optimized. The
pH =5.5 was observed optimum pH for the maximum removal of phenol. The equilibrium adsorption data of phenol showed good correlated to Freundlich and Redlich-Peterson
isotherm models. Adsorption kinetic data represents to the pseudo second order kinetic model. The maximum uptake capacity of phenol on to TCAC was found 36.77 mg/g at
303K the negative value of showed the process is spontaneous. The Taguchi experimental design was used to optimize the process variable for Phenol –TCAC system.
