Sorption mechanism of DDT from aqueous phase.
Sorption is one among the many techniques available for the removal of organic materials from potable water and waste water. Use of locally available Wood Charcoal (WC) is essential in place of costly activated charcoal to make the process more economical and lucrative. The vital objective of this investigation was to assess the performance of WC for the removal of DDT from the aqueous phase. The influence of important factors like, particle size, pH, and time of contact, which affects the sorption process was studied in this investigation using batch experiments. The removal kinetics were carried out under the temperature 27 degrees +/- 1 degrees C (room temperature) and the sorption kinetics constants were evaluated. Sorption equilibria study has also been carried out to develop the Freudlich's sorption isotherm equation from which the ultimate sorption capacity of WC for sorption of DDT was calculated.
