摘要

以丝瓜海绵(LS)为原料,以KOH为活化剂,在600℃下热解制备了一种吸附盐酸土霉素(OTCH)的潜在生物炭(KLSF-BC)。采用响应面法(RSM)确定了最佳制备参数(首次热解温度573℃,热解时间138 min, LSF-BC/KOH: 1:3, m/m)和吸附条件(OTCH浓度100 mg L−1,吸附剂用量0.84 g L−1,吸附时间28 min,初始溶液pH: 5.1),在此条件下,KLSF-BC对OTCH的吸附量为662.96 mg g−1。OTCH在KLSF-BC上的吸附数据符合拟二阶模型和Freundlich模型。OTCH的去除机制包括氢键、π -π EDA相互作用、孔隙填充和静电相互作用。该研究证实了KLSF-BC去除废水中OTCH的巨大潜力和重要应用前景,为生物质资源利用和抗生素处理提供了有价值的参考。

Oxytetracycline Hydrochloride Adsorption by Biochar From Loofah Sponge Using Response Surface Method

A potential biochar (KLSF-BC) was prepared by pyrolysis of loofah sponge (LS) at 600°C using KOH as an activator to adsorb oxytetracycline hydrochloride (OTCH). The response surface method (RSM) was applied to obtain the best preparation parameters (the first pyrolysis temperature of 573°C and pyrolysis time of 138 min, LSF-BC/KOH, 1:3, m/m) and adsorption conditions (OTCH concentration: 100 mg L−1, adsorbent dosage: 0.84 g L−1, adsorption time: 28 min, initial solution pH: 5.1), under which the adsorption capacity of KLSF-BC for OTCH was 662.96 mg g−1. The adsorption data of OTCH on KLSF-BC conformed to the pseudo-second-order model and Freundlich model. The removal mechanisms of OTCH involved hydrogen bonding, π–π EDA interaction, pore filling, and electrostatic interactions. The study confirmed the great potential and significant application prospects of KLSF-BC for removing OTCH from wastewater, providing a valuable reference for biomass resource utilization and antibiotics treatment.
