Abstract

Seeking eco-friendly, highly-efficient, low-cost, and robust adsorbents to remove oil from water resources are very much in demand. In this work, an environmentally friendly, recyclable, superhydrophobic, and superoleophilic seashell/epoxy resin/polyurethane (EP/SPU) sponge with contact angle of 174.10 ± 0.47˚ was prepared. EP/SPU sponge demonstrated high adsorption capacity in the range of 28.03–42.17 g/g times more than of its own weight for five oils and four organic solvents. The EP/SPU sponge was used 10 times for the adsorption of the oils and organic solvents with no significant loss in its adsorption capacity. The mechanical test suggested that the lightweight EP/SPU sponge is not compressible compared with neat polyurethane (PU) sponge. The volume of neat PU sponge decreased from 2.28 to 1.14 cm³ while the EP/SPU sponge volume (2.28 cm³) did not change. As a result, EP/SPU sponge is expected to be a promising sorbent for potential applications in the cleanup of oil spills from water.

一种环保超疏水改性聚氨酯海绵，用于高效油水分离

寻找环保、高效、低成本和强大的吸附剂从水资源中去除石油的需求非常大。本研究制备了一种接触角为174.10±0.47˚的超疏水、超亲油、环保、可回收的EP/SPU海绵。EP/SPU海绵对5种油脂和4种有机溶剂的吸附量为其自重的28.03 ~ 42.17 g/g。EP/SPU海绵对油类和有机溶剂的吸附次数为10次，吸附量无明显下降。力学试验表明，与纯聚氨酯(PU)海绵相比，轻质EP/SPU海绵具有不可压缩性。纯PU海绵体积从2.28 cm3下降到1.14 cm3, EP/SPU海绵体积(2.28 cm3)没有变化。因此，EP/SPU海绵有望成为一种很有前途的吸附剂，在清除水中溢油方面具有潜在的应用前景。

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
