Abstract
In this work, we used coffee ground, iron ore and copper salts as raw materials to prepare Fe0 and Cu0 bimetal nanoparticles loaded biochar composites (CG\Fe-Cu). The composite can efficiently remove refractory tetrachloropicolinic acid (TCPA) from high saline organic wastewater (HSOW) due to the dual role of direct reduction by Fe-Cu bimetals and oxidation by in-situ generated reactive oxygen species. Nearly 95% of TCPA (10 mg L−1) was eliminated by 10 g L−1 of CG\Fe-Cu within 6 h in a NaCl solution of 3 g L−1, suggesting the good application potential in treatment of HSOW.
在这项工作中，我们以咖啡渣、铁矿石和铜盐为原料制备了Fe0和Cu0双金属纳米颗粒负载的生物炭复合材料（CG\Fe-Cu）。由于Fe-Cu双金属的直接还原和原位生成的活性氧的氧化的双重作用，该复合材料可以有效地从高盐有机废水中去除难降解的四氯吡啶酸。在3 g L−1的NaCl溶液中，10 g L−L的CG\Fe-Cu在6 h内消除了近95%的TCPA（10 mg L−1），表明其在处理HSOW中具有良好的应用潜力。
