Abstract:Penelitian ini bertujuan untuk mengetahui pengaruh variasi temperatur aktivasi (600 o C, 700 o C, 800 o C, dan 900 o C) terhadap daya serap logam timbal (Pb) dan seng (Zn) menggunakan arang aktif kayu mahoni. Arang aktif dihasilkan melalui proses preparasi, karbonasi dan aktivasi untuk menghasilkan butiran adsorben 100 mesh. Massa adsorben masing-masing 10 gr dan waktu kontak 100 menit. Adsorben dimasukkan ke dalam labu elemenyer yang terisi air logam kemudian dihomogenkan dan dilihat penurunan konsentrasi air… Show more
