Heavy metals are considered among the most dangerous pollutants to the environment because of their non-degradation and accumulation and the possibility of leakage to water sources and foods then to many of the living organisms. Accumulation of these metals in the living organisms causes many serious diseases that often lead to death. The Groundwater is considered one of important sources of contamination by the heavy metals. So, treatment of this water should be carried out to dispose these pollutants. Thus, this research aimed to study the removal of a number of heavy metals "" copper, nickel, lead, zinc, iron"" in addition to water hardness from the groundwater using an adsorbent material that was obtained from the...
