Abstract
Geopolimer merupakan polimer anorganik yang tersusun dari ikatan Si-O-Al. Geopolimer
dapat diperoleh dari material alumino-silikat seperti abu terbang yang direaksikan dengan
aktivator alkali. Pada penelitian ini, abu terbang yang merupakan limbah padat dari proses
pembakaran batubara dimanfaatkan sebagai geopolimer dengan aktivator alkali campuran
larutan NaOH 10 N dan larutan natrium silikat. Geopolimer yang diperoleh digunakan untuk
mengadsorpsi logam berat mangan (Mn). Faktor-faktor yang mempengaruhi proses adsorpsi,
yaitu konsentrasi awal larutan logam berat Mn dan waktu kontak, dipelajari pada penelitian
ini selain dilakukan juga kajian isoterm dan kinetika adsorpsi. Hasil yang diperoleh
menunjukkan bahwa semakin tinggi konsentrasi awal larutan logam berat Mn maka semakin
rendah efisiensi adsorpsi yang diperoleh. Sementara itu proses adsorpsi logam berat Mn oleh
geopolimer mencapai kesetimbangan setelah 120 menit. Berdasarkan kajian isoterm dan
kinetika adsorpsi yang telah dilakukan, adsorpsi logam berat Mn oleh geopolimer dari abu
terbang mengikuti model isoterm Langmuir dan model kinetika order dua semu.
