Background: Adsorption method, using activated carbon as an adsorbent, is being widely employed
for the treatment of Copper(II) in effluent streams as the technique is simple, economical and effective.
Method: The activated carbon despite being extensively used to remove copper(II) from the water and
wastewater remains expensive. Application of the low cost adsorbents, prepared from agricultural wastes,
have been explored by several researchers for the removal of Copper(II).
Conclusion: This review highlights the adsorption potential of various agricultural waste based adsorbents
along with activation methods, experimental conditions to achieve the optimum results, factors affecting the
adsorption, adsorption isotherms and models
