Arabian Journal of Chemistry, Journal Year: 2024, Volume and Issue: 17(4), P. 105669 - 105669

Published: Feb. 8, 2024

The adsorption characteristics of Cd2+ and Pb2+ with biochars have been widely reported. However, the desorption characteristics, chemical speciation, stability adsorbed on remain unclear. In this work, rice straw were obtained at different pyrolysis temperatures (RSBC300, RSBC500, RSBC700). speciation Cd- Pb-loaded investigated through Tessier sequential extraction agents, possible quantitative mechanisms metal-laden revealed. Pyrolysis temperature influenced properties obviously, including surface morphology, element mineral composition, carbon structure defects. RSBC700 RSBC500 exhibited highest capacity toward Pb2+, respectively. majority metal ions are distributed in carbonate fraction exchangeable fraction. Cd Pb all metal-loaded showed a high risk assessment code values larger than 50 %. HCl EDTA-2Na could desorb most from Cd-laden biochars, high-temperature Pb-laden biochars. Precipitation minerals (Qpre, 52.77 %–82.37 %) interaction π-electrons (Qπ, 16.57 %–30.26 main for whereas precipitation 18.82 %–58.71 ion exchange (Qexc, 19.18 %–48.81 removal Pb2+. Therefore, not stable easily released to environment, which potential environmental risk.
