摘要

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。

Biochar supported Fe-Cu bimetal composites prepared with waste materials for removal of tetrachloropicolinic acid from high salinity wastewater

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.

期刊介绍： Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
