The use of polymeric adsorbents for the removal of azo dyes from solution has
been reviewed. Adsorption techniques are widely used to remove certain
classes of pollutants from waters, especially those which are not easily
biodegradable. The removal of azo dyes as pollutants from wastewaters of
textile, paper, printing, leather, pharmaceutical and other industries has
been addressed by the researchers. The wider use of already available
adsorbents is restricted due to their high costs which lead to investigation
and development of new materials that can be cheaper, eficient and easy
regenerated. The aim of this article is to present to the readers the
widespread investigations in recent years of synthetic and natural polymers
as adsorbents and potential replacement of conventional adsorbents. This
review presents only the data obtained using raw, hydrogel, grafted and
crosslinked forms of synthetic and nature based polymers, and the discussion
is limited to these polymer-based materials and their adsorption properties.
Keywords: adsorption, azo dyes, synthetic polymers, hydrogels, natural polymers
