Removal of Multi Heavy Metals in One Batch System onto Surface of Activated Palm Kernel

Abstract

This paper investigating the ability of palm kernel as a natural adsorbent for the removal of multi heavy metals from polluted real sample. Batch method of extraction was applied to determine the physic-chemical properties of adsorbent material. Results showed maximum removal of 70.5% (pH 3), 80.5% (pH 5) 73.5% (pH 9) for Cr (IV), Cu(II) and Pb(II) metal ions, respectively. The method was applied for the removal of the studied metal ions from a real water sample, and the recovery was recorded in the order Pb(II) > Cu(II) > Cr(VI). These findings conformed the potential ability of palm kernel as a good adsorbent for the removal of Cr (VI), Cu (II) and Pb(II) from real sample.
