近日,中国科学院合肥物质科学研究院技术生物与农业工程研究所研究员吴正岩课题组制备出一种磁性多孔纳米复合材料,可有效去除水体中的重金属,该工作为降低环境中重金属的危害提供新思路,具有较好的应用前景。六价铬是环境中普遍存在的一种毒性重金属离子,具有致癌、致畸、难降解和生物累积性等危害,威胁生态环境和人类健康。近年来,利用纳米材料去除六价铬成为环境领域的 Recently, Wu Zhengyan, a researcher at Institute of Technical Biology and Agricultural Engineering, Hefei Institute of Material Science, Chinese Academy of Sciences, prepared a magnetic porous nano-composite material which can effectively remove heavy metals in water. This work provides a new idea for reducing the harm of heavy metals in the environment , Has a good application prospects. Hexavalent chromium is a common toxic heavy metal ions in the environment, with carcinogenic, teratogenic, refractory and bioaccumulative hazards, threatening the ecological environment and human health. In recent years, the use of nanomaterials to remove hexavalent chromium has become an environmental field
