Adsorption is considered to be a simple, low cost, and effective technique to decontaminate polluted (waste)water. A lot of research has been done on the application of commercial activated carbon, a traditional adsorbent, that gives satisfactory results but its application is restricted due to high commercial costs. For this purpose, researchers, based also on the concept of green chemistry and circular economy, turn their efforts to finding other adsorbents that are economical, eco-friendly, and abundant. Luffa cylindrica has many applications in medicinal, industrial, and cosmetic sectors. This review article focuses on the alternative use of Luffa biomass (prior and after chemical modification) in the (waste)water treatment process. Specific emphasis is given to the effect of adsorption parameters (such as initial concentration, solution pH, contact time, that affected the adsorption process and on the thermodynamic of the adsorption. Adsorption isotherms and kinetic modeling are also presented and discussed. The adsorption capacities estimated to lie between 2.335 mg/g and 714 mg/g for toxic metals, 9.63 mg/g and 210.97 mg/g for dyes, and 9.25 mg/g and 278 mg/g for emerging pollutants.

吸附被认为是一种净化污染（废水）水的简单，低成本且有效的技术。关于商业活性炭（一种传统的吸附剂）的应用，已经进行了许多研究，其效果令人满意，但是由于高商业成本，其应用受到了限制。为此，研究人员还基于绿色化学和循环经济的概念，将工作转向寻找其他经济，环保和丰富的吸附剂。丝瓜在医药，工业和化妆品领域有许多应用。这篇评论文章重点介绍在废物废水处理过程中Luffa生物质的替代用途（化学改性之前和之后）。特别强调了影响吸附过程的吸附参数（如初始浓度，溶液pH，接触时间）的影响以及对吸附热力学的影响，并给出并讨论了吸附等温线和动力学模型，估算了吸附容量对于有毒金属，其含量介于2.335 mg / g至714 mg / g之间；对于染料，其含量介于9.63 mg / g至210.97 mg / g之间；对于新兴污染物，其含量介于9.25 mg / g至278 mg / g之间。
