Abstract

Magnetic biochar derived from agricultural biomass has been recognized as a cost-effective biochar sorbent for phosphate removal. This study evaluated the use of novel Fe/Mg-biochar nanocomposites (WBC1x), prepared by impregnating ground walnut shell in a solution with a different molar ratio of Fe to Mg, then pyrolyzing slowly, at a temperature of 600 °C, to remove phosphate. The results showed that MgO and FeO were loaded onto the biochar successfully through the impregnation-pyrolysis method and the composites were able to be separated easily by magnetic field. Meanwhile, a higher surface area and point of zero charge on WBC1x were observed compared to the non-magnetic biochar (WBC). Moreover, the isothermal adsorption and kinetics data further suggested the that phosphate adsorption onto WBC1x resulted from chemisorption. Additionally, the maximum phosphate adsorption capacity of WBC1x was 6.9 mg.g, obtained though the Langmuir-Freundlich model, which was threefold higher than WBC, where MgO addition could enhance the adsorption capacity of WBC1x markedly by improving the surface charge.

摘要

源自农业生物质的磁性生物炭已被公认为是一种用于去除磷酸盐的经济高效的生物炭吸附剂。本研究评估了新型铁/镁生物炭纳米复合材料（WBC1x）的使用情况，该材料通过将磨碎的核桃壳浸渍在具有不同铁镁摩尔比的溶液中，然后在600℃下缓慢热解来制备，以去除磷酸盐。结果表明，通过浸渍-热解法成功地将氧化镁和氧化亚铁负载到生物炭上，并且复合材料能够通过磁场轻松分离。同时，与非磁性生物炭（WBC）相比，观察到WBC1x具有更高的表面积和零电荷点。此外，等温吸附和动力学数据进一步表明，磷酸盐在WBC1x上的吸附是由化学吸附引起的。此外，通过Langmuir-Freundlich模型获得的WBC1x的最大磷酸盐吸附容量为6.9 mg/g，比WBC高三倍，其中添加氧化镁可以通过改善表面电荷来显著提高WBC1x的吸附容量。
