Abstract

Water is a primary element for all living things, and we need water for each and every day- to-day activity related to agricultural, industrial, and domestic cares and, thus, its quality influences all aspects of human life including energy, food, health, and economy. Safe drinking water is our primary need to protect our life and thus developing efficient and affordable techniques for water treatment to access potable water to the humanity. Water pollution is one of the severe environmental and health problems worldwide. Pollutants in water can be of organic, inorganic, heavy metals, microbial, and radioactive species, which may be in different forms viz. suspended, dissolved, or dispersed materials. The water quality is mainly affected by industrial discharges, agricultural activities, mismanagement of hazardous materials, etc. Nowadays, nanotechnology offers the possibility of an efficient removal of water pollutants including metals, organic dyes, bacteria, parasites, etc. Magnetic nanomaterials like iron oxide (Fe 3 O 4 ) are very promising materials used in water decontamination particularly for heavy metals and dyestuffs because of their ease of separation through external magnet, high surface area, unique morphology as well as their high stability. These materials can be used as adsorbent, photocatalyst, and coagulating agents for water remediation based on their composite materials or surface functionalities.
磁性材料去除水污染物的研究
水是所有生物的基本元素,我们的农业、工业和家庭护理等日常活动都需要水,因此,水的质量影响着人类生活的方方面面,包括能源、食品、健康和经济。安全的饮用水是我们保护生命的首要需求,因此开发有效和负担得起的水处理技术,为人类提供饮用水。水污染是世界范围内严重的环境和健康问题之一。水中的污染物可以是有机、无机、重金属、微生物和放射性物质,它们可能以不同的形式存在,即悬浮、溶解或分散的物质。水质主要受到工业排放、农业活动、有害物质管理不善等因素的影响。如今,纳米技术提供了有效去除水污染物的可能性,包括金属、有机染料、细菌、寄生虫等。磁性纳米材料如氧化铁(fe3o4)是非常有前途的材料,用于水净化,特别是重金属和染料,因为它们易于通过外部磁铁分离,高表面积,独特的形态以及高稳定性。这些材料基于其复合材料或表面功能,可作为水修复的吸附剂、光催化剂和混凝剂。
