One of the extremely major problem facing the modern world is the shortage of natural resources
and the environmental pollution resultant from industrial activities. It is no doubt that water is an
important natural resource and it needs protection. Although, several physical, chemical and
biological treatment methods have been developed and successfully adopted in to the industry to
solve this problem, in recent years, adsorption technique has been re-gaining interest due to its
advantages on the removal of stable pollutants, flexible process design and process economy. In
adsorption, one of the key parameter that influence treatment recovery is the adsorbent material.
Therefore, adsorbent materials are of great scientific and technological interest owing to their
ability to interact with specific substances and efficiently separate them from a mixture.
Over the last years, nanotechnologies have been implemented in almost all branches of human
live. Until now, numerous nanomaterials have produced and used to eliminate inorganic and
organic species from wastewater effluents, in many cases, it was found more efficient than the
conventional adsorbents. Within this group, hydrogels which consisted a group of polymeric
materials has received high interest due to the several advantages. The hydrophilic structure of
which renders them capable of holding large amounts of water in their three-dimensional networks.
Extensive employment of these products in a number of industrial and environmental areas of
application has considered to be of prime importance [1].
However, relatively lower mechanical properties, required a long time to reach a saturated state
and difficulties associated with the regeneration and disposal are the main obstacles for their
practical application. Therefore recently, some attempts have been performed to made them more
functional (well-defined porosities, more controllable surface properties) by the incorporation of
nano- or micro-particles of inorganic materials, such as clay minerals graphene oxide, iron oxide
CNT, etc. into the polymer networks [2].
In this article, the fundamental concepts, classification, physical and chemical characteristics,
production methods and technical feasibility of their utilization was reviewed base on the composite
hydrogel. A special attention has given to utilization of them for wastewater purification especially
for the effluent received from textile industry.
