Kinetics and thermodynamic studies on the removal of crystal violet by pomegranate peel powder

N. Pandiaraj, K. Ananthakumar

Abstract :

The present study deals with the removal of crystal violet (CV) by Pomegranate peel powder (PPP). The effect of initial concentration of dye, dose of adsorbent, contact time and temperature on the removal of crystal violet by adsorption on PPP have been studied. The percentage removal of dye was found to decrease with increase in initial concentration of dye. The percentage removal of dye increases exponentially with increase in dose of adsorbent. This was due to the availability of active sites. The percentage removal of dye was found to increases with increase in contact time. From this the kinetics of adsorption process was manipulated. The kinetic data is well fitted with second order kinetics. The percentage removal of dye was found to increases with increase in temperature. From this data the thermodynamic parameters such as ?H0, ?Go and ?S0 were calculated.
