Article Synopsis
- Various amendments, including biochar, are being investigated for their effectiveness in reducing heavy metal availability in contaminated soils.
- In a study, two sizes of oil palm empty fruit bunch biochar were tested at different rates on soils contaminated with cadmium (Cd) and lead (Pb), with mustard plants used to assess the impact.
- The results showed that applying 1% fine EFBB improved growth in Cd-contaminated soil and significantly reduced metal concentrations in plants, while the effects in Pb-contaminated soil were not significant.
Biochars have been successfully used to reduce bioavailability and leaching of heavy metals in contaminated soils. The efficiency of biochar to immobilize heavy metals can be increased by reducing the particle size, which can increase the surface area and the cation exchange capacity (CEC). In this study, the empty fruit bunch biochar (EFBB) of oil palm was separated into two particle sizes, namely, fine (F-EFBB < 50 µm) and coarse (C-EFBB > 2 mm), to treat the contaminated soil with Cd and Pb.

The efficiency of biochar as a biosorbent of heavy metals can be increased by reducing the particle size, exposing the inner pores and their functional groups. In this study, the empty fruit bunch biochar (EFBB) of oil palm was separated into three particle sizes, fine (F-EFBB < 50 μm), medium (M-EFBB 250-500 μm) and coarse (C-EFBB > 2000 μm) to compare their physical and chemical characteristics and their adsorption capacity for lead.
