The adsorption removal of anti-inflammatory drugs from water by diverse materials has drawn great attention. This study investigated the adsorption of sulfamethoxazole (SMX) by two types of materials, UiO-66 and UiO-66-BC composites. Highly porous MOF composites with functional groups were synthesized by combining UiO-66 with corncob-based biochar at different molar ratios. SEM results showed that macroporosity of UiO-66-BC composites was increased by increasing the ratio of biochar. It was found that UiO-66-BC composites displayed highly improved adsorption performance of SMX relative to pristine UiO-66. UiO-66-BC (5%) had the highest SMX adsorption capacity, about 2.4 times those of pristine UiO-66. It was the high surface area of UiO-66 and redundant functional groups of biochar that increased the adsorption performance of composites. Moreover, UiO-66-BC can be reused and displayed the competitive adsorption efficiency after successive adsorption, which made it a potential adsorbent for the removal of SMX from water.

使用UiO-66和UiO-66-BC复合材料吸附去除水中的磺胺甲恶唑

多种材料从水中吸附去除抗炎药引起了极大的关注。这项研究研究了UiO-66和UiO-66-BC复合材料这两种类型的材料对磺胺甲恶唑(SMX)的吸附。通过将UiO-66与玉米芯生物炭以不同的摩尔比混合,可以合成具有官能团的高多孔MOF复合材料。SEM结果表明,UiO-66-BC复合材料的大孔隙度通过增加生物炭的比例而增加。已经发现,相对于原始的UiO-66,UiO-66-BC复合材料显示出极大改善的SMX吸附性能。UiO-66-BC(5%)具有最高的SMX吸附能力,约为原始UiO-66的2.4倍。UiO-66的高表面积和生物炭的多余官能团提高了复合材料的吸附性能。而且,
