Abstract:
Water security and industrial wastewater treatment are significant global concerns. One of the main issues with environmental contamination has been the discharge of dye wastewater from the textile and dye industries, contributing to an ever-growing problem with water pollution, poisoning water supplies, and harming the ecosystem. The traditional approach to wastewater treatment has been found to be inefficient, and biosorption techniques and mechanisms have been proven to be a successful replacement for conventional methods. Recent developments have led to the recognition of fibrous materials as an environmentally friendly option with broad application in several industries, including wastewater treatment. This review explores the potential of fibrous materials produced by the electrospinning technique as adsorbents for wastewater treatment, while at the same time, for the removal of adsorbates such as oil, dyes, heavy metals, and other substances, as reported in the literature. Textile wastewater filtering structures, produced by electrospinning, are summarized and the use of synthetic and natural polymers for this purpose is discussed. The limitations of electrospun textile wastewater filtering structures are also mentioned. Electrospun nanofibrous membranes appear to be a very promising route to filter textile wastewater and therefore contribute to water reuse and to reducing the contamination of water courses.
摘要:
水安全和工业废水处理是全球关注的重大问题。环境污染的主要问题之一是纺织和染料行业的染料废水的排放,导致日益严重的水污染问题,中毒供水,损害生态系统。已发现传统的废水处理方法效率低下,和生物吸附技术和机制已被证明是传统方法的成功替代品。最近的发展使人们认识到纤维材料是一种环境友好的选择,并在多个行业中得到广泛应用。包括废水处理。这篇综述探讨了通过静电纺丝技术生产的纤维材料作为废水处理吸附剂的潜力,同时,用于去除吸附物,如油,染料,重金属,和其他物质,正如文献报道的那样。纺织废水过滤结构,通过静电纺丝生产,进行了总结,并讨论了合成和天然聚合物用于此目的的用途。还提到了电纺纺织废水过滤结构的局限性。静电纺丝纳米纤维膜似乎是过滤纺织废水的非常有前途的途径,因此有助于水的再利用和减少水道的污染。
