ABSTRACT

Sample of waste collected at Kanwuri Area Sokoto, was analyzed using a groundnut shell and tea bag as natural adsorbent, by adopting the method of atomic absorption spectrophotometry. And this research showed that groundnut shell and tea bag can be effectively used as an excellent adsorbent for the removal of Cu, Zn, Pb, and Cr, from aqueous solution. This study also highlights the effect of different parameters such as, contact time, PH, adsorbent dose initial concentration of heavy metal ions. The concentration of heavy metal ions obtained from the analysis, were calculated to be 99.2%, 8.0%, 96.0%, 94.0%, and 92.0%, for Copper, Zinc, Nickel, Lead and Chromium, respectively.
