Abstract

The rising shortage of water resources and the need to provide water in many regions like Morocco around the world has been crucial and will become increasingly alarming in the future. Water bodies can be practically polluted or impaired by industrial, agricultural, and anthropogenic waste. Heavy metals are widely known environmental contaminants due to their toxicity, prevalence, and bioaccumulation. They build up in the environment, disrupting the food chains as chronic pollutants. In organisms, including humans, the deposition of possibly hazardous heavy metals poses a significant threat to health. This review paper highlights the present research on heavy metal removal, focusing on adsorbents and techniques accessible and feasible, such as adsorptive separation by substances, including a metal oxide, graphene, zeolite, and carbon-based composites. These techniques received a lot of acknowledgment due to their significant active surface area, high proportion of functional groups, increased chemical and thermal stability, and impressive adsorption efficiency and efficacy. The economic aspects and feasibility of adsorbents have also been presented.

不同吸附技术去除水中重金属的比较研究

水资源日益短缺，世界各地像摩洛哥这样的许多地区都需要供水，这一点至关重要，而且在未来将变得越来越令人担忧。水体实际上可能受到工业、农业和人为废物的污染或损害。重金属因其毒性、普遍性和生物累积性而成为众所周知的环境污染物。它们在环境中积累，作为慢性污染物扰乱食物链。在包括人类在内的生物体中，可能有害的重金属的沉积对健康构成重大威胁。这篇综述文章重点介绍了目前对重金属去除的研究，重点介绍了可获得和可行的吸附剂和技术，如通过金属氧化物、石墨烯、沸石和碳基复合材料等物质进行吸附分离。这些技术因其显著的活性表面积、高比例的官能团、增加的化学和热稳定性以及令人印象深刻的吸附效率和功效而受到广泛认可。还介绍了吸附剂的经济性和可行性。

期刊介绍： Biointerface Research in Applied Chemistry is an international and interdisciplinary research journal that focuses on all aspects of nanoscience, bioscience and applied chemistry. Submissions are solicited in all topical areas, ranging from basic aspects of the science materials to practical applications of such materials. With 6 issues per year, the first one published on the 15th of February of 2011, Biointerface Research in Applied Chemistry is an open-access journal, making all research results freely available online. The aim is to publish original papers, short communications as well as review papers highlighting interdisciplinary research, the potential applications of the molecules and materials in the bio-field. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible.
