Abstract

Water contamination over the years due to hazardous organic and inorganic pollutants poses an immediate threat to both the environment and human health. Extensive research has been conducted on the application of the adsorption technique to treat these effluents. With a focus on adhering to the principles of Green Chemistry and the circular economy, researchers are directing their efforts toward discovering economical, biodegradable, and readily available adsorbents. In this context, the present review article offers insights into recent studies regarding the utilization of the natural biosorbent Luffa cylindrica. This porous, environmentally friendly, and non-toxic material shows promise in the realm of wastewater treatment. Emphasis was also given to several fiber modifications aimed at enhancing the adsorption capacity of this biosorbent. Additionally, comprehensive physicochemical characterizations were conducted, including SEM, TEM, FTIR, XRD, N₂ adsorption and desorption and contact angle analyses. The impact of adsorption parameters was discussed in detail. The review delves into kinetic, equilibrium, and thermodynamic data, which have been presented and analyzed. Mechanistic insights into the adsorption interactions between the adsorbent and adsorbate are depicted through illustrative diagrams. Ultimately, the findings underscore the potential of both Luffa and Luffa-based materials as promising candidates for effective wastewater treatment applications.

在废水处理应用中作为生物吸附剂的丝瓜：综合评述

多年来，有害有机和无机污染物造成的水污染对环境和人类健康都构成了直接威胁。人们对应用吸附技术处理这些污水进行了广泛的研究。为了遵循绿色化学和循环经济的原则，研究人员正在努力探索经济、可生物降解且易于获得的吸附剂。在此背景下，本综述文章介绍了有关利用天然生物吸附剂丝瓜的最新研究。这种多孔、环保、无毒的材料在废水处理领域大有可为。研究还重点关注了旨在提高这种生物吸附剂吸附能力的几种纤维改性方法。此外，还进行了全面的物理化学表征，包括 SEM、TEM、FTIR、XRD、N2 吸附和解吸以及接触角分析。详细讨论了吸附参数的影响。综述深入探讨了动力学、平衡和热力学数据，并对这些数据进行了展示和分析。通过示意图描述了吸附剂和吸附质之间的吸附相互作用机理。最终，研究结果强调了丝瓜和以丝瓜为基础的材料作为有效废水处理应用的候选材料的潜力。

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
