  ABSTRACT: The study investigated using rice husk biochar (RHB) to immobilize TNT and RDX explosives in soil at demining sites in Amuru District, Uganda. RHB produced via pyrolysis at 550˚C was applied at a rate of 5% w/w to soil samples spiked at 50 µg∙g−1 RDX or TNT. The Liquid chromatography-tandem mass spectrometer (LC-MS/MS) analysis showed that the RHB immobilized 56% - 67% of RDX and 55% - 69% of TNT. The biochar’s porous structure and surface functional groups facilitated the explosive adsorption, reducing bioavailability. This demonstrates RHB’s effectiveness as an environmentally friendly and cost-effective remediation strategy.
