ADSORPSI TIMBAL (Pb) DAN ZINK (Zn) DARI LARUTANNYA MENGGUNAKAN ARANG HAYATI (BIOCHARCOAL) KULIT PISANG KEPOK BERDASARKAN VARIASI pH
Abstract: The research has
been done concerning the adsorption of biological charcoal from kapok banana
peel onPb and Zn metal from solution. This study aimed to determine the ability
of a banana peel charcoal to adsorbPb and Zn metal from its solution. The
method used in this research was a laboratory experiment by using activated
charcoal of banana peel as adsorbent ofPb and Zn metal. The absorbed Pb and Zn
were measured by using Atomic Absorption Spectrometry (AAS). The results showed
that the optimum pH of adsorption of Pb and Zn was obtained at pH 4 and pH 6
respectively with the concentration of Pb and Zn metal was 19.40 mg/g and 21.17
mg/g respectively.
Keywords: Adsorption,
