| Abstract: | Decolourization of
pulp and paper mill wastewater better known as black liquor using low cost
adsorbents is under investigation over the years. Colour of the black liquor is
aesthetically harmful to the environment as it contains certain toxic and xenobiotic
compounds. Polyvinyl chloride (PVC) is water insoluble, low crystalline polymer
and cost friendly. Alkalies and acids present in wastewater do not affect the
basic structure of this linear macromolecule. Physicochemical method for
decolourization was adopted for process simplification. Contact-time, effect of
dosages, adsorption dynamics and adsorption isotherms were few parameters
examined for the study. Moderate to fair results were obtained rendering PVC as
a substitute to some high-cost polymers used as adsorbents. The probable
interactions between chromophoric components of black liquor and PVC has been
discussed. |
