摘要: Sediment samples with high organic carbon contents (22.04% and 8.46%) were collected thermally-treated using a method analogous to biochar production. The obtained sediments (TTSs) showed much higher degree of capture in comparison derived from common biomass, indicating potential use TTSs soil amendment sequestration. Their sorption contaminants was also investigated sulfamethoxazole (SMX) as model sorbate. SMX increased greatly pyrolytic temperature. Desorption ratio the adsorbed generally decreased temperature solid-phase concentrations. thermodynamic analysis that entropy increase (positive ΔS) well related desorption concentration for original sediments. fate-controlling effect TTS application should be evaluated combining sorption/desorption studies.
