Immobilization of Uranium and Thorium in Mining-affected Soils using Oil Palm Frond Activated Carbon

Abstract

Soil contamination from uranium and thorium mining creates serious environmental and health risks. This happens due to radionuclides leaking into the affected soils. This study aims to immobilize U and Th in mining-affected soils using oil palm fronds activated carbon, OPFAC. OPFAC was chosen because it can effectively absorb these harmful radionuclides, helping limit their concentration and movement in contaminated soils.
