摘要

摘要: 为有效解决水体重金属污染问题，通过热解炭化的方法，以餐厨垃圾（FW）为原料制备餐厨垃圾生物炭（FWB），研究FWB对Cu²⁺、Zn²⁺和Pb²⁺的吸附性能。在单金属体系中，FWB对Cu²⁺、Zn²⁺和Pb²⁺的吸附容量分别为40.283，37.082，51.565 mg/g。与单重金属体系相比，FWB在多金属体系下由于离子间的吸附发生竞争反应，导致吸附性能降低，且FWB对重金属的吸附顺序为Cu²⁺＞Pb²⁺＞Zn²⁺。结合相关表征，推测FWB对3种重金属的吸附机理包括含氧官能团的离子络合、离子交换、碳酸盐的沉淀等，其中FWB中的Ca元素对Cu²⁺与其他2种重金属的吸附机理不同，Ca与Cu²⁺发生络合反应，生成相应的含Cu沉淀结构，而与Zn²⁺、Pb²⁺发生的则是离子交换反应。

Abstract: To effectively address the issue of heavy metal contamination in aquatic ecosystems， this study employed food waste （FW） as the raw material to produce food waste biochar （FWB） through pyrolytic carbonization. The adsorption performance of FWB for Cu²⁺， Zn²⁺， and Pb²⁺ was examined. In a single-metal system， the adsorption capacities of FWB for Cu²⁺， Zn²⁺， and Pb²⁺ were 40.283 mg/g， 37.082 mg/g， and 51.565 mg/g， respectively. Compared with the single heavy metal system， the adsorption performance of FWB was found diminished in the multi-metal system， which was attributed to the competitive adsorption reaction between the ions. The order of adsorption preference of FWB for the heavy metals was determined to be Cu²⁺ > Pb²⁺ > Zn²⁺. Based on the aforementioned characterization， the adsorption mechanism of FWB for the three heavy metals was inferred to include complexation with oxygen‑containing functional groups， ion exchange， and carbonate precipitation. Notably， the adsorption mechanism of Ca in FWB for Cu²⁺ differed from that for the other two heavy metals： Ca complexed with Cu²⁺ to form a Cu-containing precipitation structure， whereas ion exchange primarily occurred between Ca and Zn²⁺ and Pb²⁺.
