Nanoparticles are almost omnipresent with significant pros and cons. Scientists have ventured into environmental nanotechnology, synthesizing unique nanoparticles in the laboratory. Copper nanoparticles are an active area of research for the decontamination of water from toxic dyes in the context of environmental nanotechnology. Copper is an abundant element in our earth's crust. However, rapid aerial oxidation limits its application. The present review article focuses on removing a toxic dye crystal violet (CV) adsorption and degradation involving copper-based nanoparticles. Various synthetic protocols of such nanoparticles, removal efficiency including reusability, effect of doping and physico-chemical conditions, mechanisms, and connections towards circular economy were summarized here. A comparative account was depicted between adsorption and degradation for the elimination of CV involving copper-based nanoparticles. The current review paper will hopefully be an asset for the industries that release harmful dyes for sustainable water management.
纳米颗粒几乎无处不在，有显著的优缺点。科学家们已涉足环境纳米技术领域，在实验室中合成独特的纳米颗粒。在环境纳米技术背景下，铜纳米颗粒是用于从有毒染料中净化水的一个活跃研究领域。铜是地壳中一种丰富的元素。然而，快速的空气氧化限制了其应用。本综述文章重点关注涉及铜基纳米颗粒去除有毒染料结晶紫（CV）的吸附和降解。这里总结了此类纳米颗粒的各种合成方案、包括可重复使用性的去除效率、掺杂的影响和物理化学条件、机制以及与循环经济的联系。对涉及铜基纳米颗粒去除CV的吸附和降解进行了比较说明。本综述论文有望成为那些排放有害染料的行业实现可持续水管理的一项宝贵资源。
