Adsorption processes are being widely used in various researches for the removal of heavy metals from polluted water to make it safe as a drinking water. A simple adsorption technique followed by filtration is used for removing the heavy metals (Cu, Zn, Mn, and Cr) from polluted water. There are three types of Soils used as adsorbent (Silty, Sandy and Clay). Also, we used three types of marble powder (pure marble powder, impure marble powder, marble-granite mix powder) as adsorbent. The samples are collected from different regions of Oman. The maximum adsorption obtained is 96.01% in the case of pure marble powder with Zn heavy metal. The minimum adsorption value obtained is 6.70% in the case of impure marble powder with Mn heavy metal. In the case of soils, the best one is clay soil with Zn heavy metal (88.61%) and the worst one is Silty soil with Cr heavy metal (16.51%). In the case of marble powders, the best marble powder is the pure marble powder with Zn heavy metal (96.01%) and the worst one is marble-granite mix marble powder with Cr heavy metal (36.70%). Among all adsorbents, pure marble powder is the best as adsorbent and Zn heavy metal is the best heavy metal as adsorbate (96.01%) and the worst one is impure marble powder with Mn heavy metal as adsorbate (6.70%). The results are discussed details.
