Agricultural Waste or Residue as Adsorbent for Nickel Removal

In today’s world, water scarcity affects every corners of the world. More than 1.2
billion people do not have access to clean water resources. This problem happens
due to several reasons such as climate changes, natural disaster, contamination of
water catchment area and many more. Since water is a basic necessity for living
organism to live, a sustainable solution to water deficiency should be think of to
avoid the same problem from happening continuously. In order to materialized the
solution, thorough research on adsorption should be pursued to clean out
contaminated water as it is a valuable resource. The solution should use adsorbents
that are as cheap as possible to make it sustainable throughout the process. The
objective of this research is to find out the characteristic of agricultural waste or
residue (corn cob) to be used as adsorbents, to find out the parameters that can
affects the performance of adsorbents, to calculate the effectiveness of each
adsorbents to remove nickel ions from water and to find out economical potential of
the adsorbent.
