Abstract

A novel NaOH modified eggplant straw biochar supported green nanoscale zerovalent iron (P-nZVI/ESBC) composite was synthesized and its removal performance and reaction mechanism for tetracycline (TC) in water were investigated. Multiple characterizations showed that the prepared P-nZVI/ESBC composite contained oxygen-containing functional groups (hydroxyl, carbonyl, and carboxyl groups) and Fe species (nZVI and its oxides). The dosage of composite, temperature, and solution pH significantly affected the removal capacity of the P-nZVI/ESBC composite for TC. The Avrami fraction-order kinetic model and Sips adsorption isotherm model can fit well the removal process of TC by the P-nZVI/ESBC composite, indicating that the adsorption behavior of TC involved multiple adsorption mechanisms and chemical adsorption might occur. The maximum adsorption capacity of the P-nZVI/ESBC composite for TC was 304.62 mg g. The adsorption and reductive degradation were the dominant mechanisms of TC removal by the P-nZVI/ESBC composite. This work offers abundant information on the application of eggplant straw to manufacture biochar-based composites for the efficient removal of antibiotic contaminants from aquatic environments.

摘要

合成了一种新型的氢氧化钠改性茄子秸秆生物炭负载绿色纳米零价铁（P-nZVI/ESBC）复合材料，并研究了其对水中四环素（TC）的去除性能和反应机理。多种表征表明，制备的P-nZVI/ESBC复合材料含有含氧官能团（羟基、羰基和羧基）和铁物种（纳米零价铁及其氧化物）。复合材料的投加量、温度和溶液pH值对P-nZVI/ESBC复合材料对TC的去除能力有显著影响。Avrami分数阶动力学模型和Sips吸附等温线模型能很好地拟合P-nZVI/ESBC复合材料对TC的去除过程，表明TC的吸附行为涉及多种吸附机制，可能发生化学吸附。P-nZVI/ESBC复合材料对TC的最大吸附量为304.62 mg/g。吸附和还原降解是P-nZVI/ESBC复合材料去除TC的主要机制。这项工作为利用茄子秸秆制备生物炭基复合材料以高效去除水环境中的抗生素污染物提供了丰富的信息。
