Polyaniline (PANI) Based Composites for the Adsorptive Treatment of Polluted Water


Polyaniline (PANI) Based Composites for the Adsorptive Treatment of Polluted Water

Abu Nasar

Adsorption techniques are commonly applied for the treatment of pollutants from wastewater. Different varieties of adsorbents have been used for removing contaminants from aqueous media. Although conventional adsorbents (like activated carbon, alumina, etc.) should be preferable, their extensive application is undesirable because of the high cost and regeneration problems. To overcome these problems, attention has been directed to developing cheaper and efficient alternatives to conventional adsorbents. In this respect, the polyaniline (PANI) based composites offer suitable substitutes for conventional adsorbents due to their special properties such as easy preparation, nontoxicity and availability as active functional groups which have interactions with contaminating molecules and ions. In the present chapter different adsorption parameters, isotherms and kinetics along with their significance are described. Detailed discussions have been dedicated to the applications of PANI-based composites for the adsorptive elimination of dyes and toxic metals. The role of these adsorbents in monitoring of pesticides in water has also been discussed briefly.
