Abstract

We present a method using the material in the form of cross-linked β-cyclodextrin (CD) showing high efficiency in the simultaneous removal of hazardous pollutants from sewage, such as diclofenac (DIC), ibuprofen (IBU), ketoprofen (KETO), naproxen (NAPR), salicylic acid (SALI) and tramadol (TRAM). The material is stable and particularly easy to regenerate. The sorbent probably remembers the shape of the contaminants, which increases its sorption capacity after the second use. The kinetics of the KETO adsorption process from one-, two- and three-component solutions are well described by the pseudo-second-order model. The maximum polymer capacity was 162.60 mg g⁻¹. The interactions of KETO with CD were investigated, indicating that the main sorption mechanism is based on supramolecular interaction and uptake by a polymer network. The material is not sensitive to low pH and high salinity, so it can be used for the treatment of DIC, IBU, and KETO post-production wastewaters.

交联β-环糊精吸附去除废水中非甾体类消炎药和镇痛药

本研究提出了一种以交联β-环糊精(CD)为原料同时去除污水中有害污染物的方法，如双氯芬酸(DIC)、布洛芬(IBU)、酮洛芬(KETO)、萘普生(NAPR)、水杨酸(SALI)和曲马多(TRAM)。这种材料很稳定，特别容易再生。吸附剂可能会记住污染物的形状，这在第二次使用后增加了它的吸附能力。拟二阶模型很好地描述了KETO在一组分、二组分和三组分溶液中的吸附动力学。聚合物的最大容量为162.60 mg g−1。研究了KETO与CD的相互作用，表明其主要吸附机理是基于超分子相互作用和聚合物网络的吸附。该材料对低pH、高盐度不敏感，可用于处理DIC、IBU、KETO等生产后废水。

期刊介绍： Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
