FITOREMEDIASI LIMBAH MERKURI MENGGUNAKAN TANAMAN DAN SISTEM REAKTOR ABSTRAK Fitoremediation menggunakan tanaman teknologi yang lebih efektif dan efisien untuk membersihkan lingkungan tercemar merkuri Penelitian ini bertujuan untuk tanaman merkuri-peredam dan untuk menguji kemampuan aktivitas tanaman dalam mengurangi merkuri. Percobaan dilakukan di laboratorium FMIPA-UNSRAT. Hasil penelitian menunjukkan bahwa beberapa tanaman akumulasi Hg uch sebagai Typha sp. (84.18%), Hydrilla verticillata (83,96%), Ipomoae aquatic (83,84%), Eichhornia crassipes (81,19%), Nelubium nelumbo (80,78%).
