HEAVY METAL REMOVAL WITH ORGANIC MATERIALS

The Heavy metals that we used were: Zinc (ZnSO₄), Copper (CuSO₄), Lead (Pb(NO₃)₂), Chromium(Na₂Cr₂O₇). We used these heavy metals altogether since we tried achieving the same level of pollution like the ones in the most polluted waters flowing in N. Macedonia For our project we chose the zeolite,  burnt eggshell . The reason was that they are easily accessible, natural and cheap to people.
