氮硼掺杂牛蛙养殖污泥生物炭对四环素的吸附行为
Adsorption performance study of tetracycline in water by nitrogen and boron co-doped bullfrog culture sludge biochar
摘要
Abstract
To achieve harmless treatment of dehydrated sludge from bullfrog farming,control antibiotic pollution,and achieve the goal of waste treatment using waste,this study uses dehydrated sludge from bullfrog farming as raw material to prepare nitrogen and boron-doped sludge-based biochar(NB-SBC)through pyrolysis modification.The prepared material can effectively remove tetracycline(TC)from water.The results show that compared with the original biochar(SBC),the modified nitrogen and boron-doped sludge-based biochar(NB-SBC)contains a rich oxygen-containing functional groups,and the specific surface area of NB-SBC is significantly increased by 833.81%.The adsorption kinetics follow the pseudo-second-order kinetic model,and the adsorption isotherm conforms to the Langmuir model.The adsorption mechanism is analyzed through FT-IR and Zeta potential analysis,revealing that π-π interactions and electrostatic interactions are the primary mechanisms in the adsorption process of NB-SBC for tetracycline.This study provides a theoretical basis for the resource utilization of bullfrog farming sludge and the practical treatment of wastewater.关键词
