MODELING AND UNDERSTANDING THE ADSORPTION PROCESS OF CHLOROPHENOL ON ACTIVATED CARBON OF WASTE LEATHERSR. ANBU, A. UDAYA AND J. SAMU SOLOMONAbstract In this study, activated carbon synthesized from Waste Leathers was used as a sorbent to put off 4- chlorophenol (4-CP) from aqueous solutions. They have an effect of contact time (30-180 minutes), pH (1-6), adsorbent dosage (50-200 mg/l), and preliminary 4-CP concentration (10-60 mgl-1) in batch experiment used to be investigated on the sorption. The sorbent used to be distinct for the use of scanning electron microscopy (SEM), Fourier Transform Infrared (FTIR) spectrometer and X-ray diffraction, and XRD. Equilibrium for 4-CP sorption used to be reached at contact time of a 180 minutes. The pH of 1 used to be additionally determined to be the top of the line pH in the sorption process. Fitting the experimental statistics to special kinetic and isotherm models illustrated that the experimental facts was properly geared up via pseudo-second order kinetic (R2>0.97) and Freundlich isotherm (R2 > 0.98) models. According to the results, activated carbon prepared from Waste Leathers is a lower priced nice choice for the sorption of 4-CP from aqueous solutions |
