基于纳米颗粒的铬污染地下水修复Nanoparticle-Based Remediation of Chromium-Contaminated Groundwater
➀ 来自印度理工学院等机构的科研人员开发了一种基于纳米材料的地下水铬污染修复技术，利用羧甲基纤维素（CMC）包覆的铁纳米颗粒去除重金属。该研究发表在《水处理工程杂志》上，展示了在去除六价铬方面的高效性。➁ 研究突出了合成稳定纳米颗粒在修复中的挑战，解决了颗粒聚集的问题。➂ 开发的S-CMC-nZVI材料在各种环境条件下均表现出高效性，并在清理如贝兰杜尔湖那样的受污染沉积物方面具有潜在应用价值。➀ Researchers from the Indian Institute of Science and other institutions have developed a nanomaterial-based solution to remediate chromium-contaminated groundwater. The solution uses iron nanoparticles coated with carboxymethyl cellulose (CMC) to remove heavy metals. The research, published in the Journal of Water Process Engineering, demonstrates high efficacy in Cr6+ removal.➁ The study highlights the challenges in synthesizing stable nanoparticles for remediation, addressing the issue of particle aggregation.➂ The developed S-CMC-nZVI material is effective in various environmental conditions and has potential applications in cleaning up contaminated sediments such as those found in Bellandur Lake.
