freely available and low cost. The present study shows the feasibility of using activated
palash leaves as a sorbent for the removal of phenol through its physico-chemical charac-
teristics. To understand the behaviour/mechanism of sorption, a kinetic study has been
carried out.
2A.4.1.1 Materials and Methods
All the reagents were analytical reagent (AR) grade. Phenol was purchased from Ranbaxy
Fine Chemicals, New Delhi, India. The initial pH was adjusted with 0.1 N NaOH or 0.1
N HCl solutions. A stock solution of 1000 mg/L was prepared by dissolving accurately
weighed amounts of phenol in double distilled water (DWW). The desirable experimental
concentration of solutions was prepared by dilut
