Received: July 23, 2018 Revised: September 7, 2018 Accepted: November 7, 2018 Abstract: Introduction: The increasing level of toxic metals in the environment is causing serious repercussions on the health of human beings. To mitigate the adverse effects of heavy metal concentration in the receiving waters, it is necessary to develop an affordable cost effective technology, which is effective to remove the heavy metals. The purpose of the present work is to investigate the removal of Nickel and Zinc ions from the water using known adsorbents. Chitin is a biopolymer used as as adsorbent to remove metal ions from the solution. Chitin is inexpensive adsorbent and is available abundantly.
