Cr(VI) in aqueous solution is a serious concern that can harm human health by accumulating in the food chain. Meanwhile, the most common form of food waste (FW) disposal by landfill takes up a lot of area and pollutes the environment. As a consequence, FW was employed as a raw material in the production of food waste-derived biochar (FWB), which was then modified to produce a Ce/Fe3O4/FWB composite for high-efficiency Cr(VI) removal

Ce/四氧化三铁/食物垃圾衍生生物炭的制备，用于吸附 Cr(VI) 水溶液

水溶液中的 Cr(VI) 是一个严重的问题，它可以通过在食物链中积累来危害人类健康。同时，垃圾填埋场处理食物垃圾 (FW) 的最常见形式会占用大量面积并污染环境。因此，FW 被用作生产食物垃圾衍生生物炭 (FWB) 的原材料，然后对其进行改性以生产 Ce/Fe3O4/FWB 复合材料，以高效去除 Cr(VI)
