Abstract


Pencemaran Pb yang terjadi di dalam tanah dapat disebabkan oleh proses alam dan kegiatan antropogenik. Sumber utama polusi Pb adalah cerobong asap dari pabrik yang menggunakan bahan baku Pb, limbah dari industri penyimpanan baterai, peleburan dan ekstraksi logam dari bijih Pb, kegiatan pelapisan logam, pupuk dan pestisida, serta penggunaan Pb pada bahan aditif bensin. Pb dapat dihilangkan dengan proses fitoremediasi. Fitoremediasi merupakan proses remedasi lingkungan tercemar menggunakan tumbuhan. Penggunaan agen pengkelat seperti EDTA dalam proses fitoremediasi logam berat Pb dapat membantu proses fitoektraksi dan meningkatkan kelarutan Pb di tanah agar dapat dengan mudah diserap oleh tumbuhan. EDTA merupakan agen pengkelat yang terbukti efektif untuk Pb karena memiliki afinitas yang kuat dengan Pb.

Keywords
