Oil spills adsorption and cleanup by polymeric materials: A review

Abstract

Oil spills are environmental disasters that impact human, plants, and wild life, such as birds, fish, and mammals. This article has comprehensively reviewed the progress made in oil spills remediation especially by polymeric adsorbents. Various methodologies involved in oil sorption using porous polymer network and its recovery are thoroughly discussed. In addition, new concepts and development in synthesizing sponge, fiber, graft, and crosslinked polymer networks are also collected briefly and future perspectives are suggested. With their unique physical and mechanical properties coupled with their very high surface area and small pore sizes, polymer-based adsorbents can be used as advanced materials for cleaning up oil spills.

Surface engineering of a superamphiphilic, self-growing fibrous Janus membrane prepared from mycelium

“…As PP is widely used in oil spill remediation, 47,48 we investigated its surface modication and potential oil-uptake enhancement using mycelium. Compared with the original PP, PP M showed a signicant change in oil and water sorption (Fig.…”

Hydrophobically modified nano‐SiO2 in situ loaded on polyurethane foam as a potential carrier for marine oil spill

“…Compared with the above methods, adsorption technology is more popular because of its simple operation, environmentally friendly and low operating cost. 5 The adsorbents mainly include natural and synthetic adsorption materials. The natural adsorption materials are inexpensive and readily available, such as activated carbon, clay, bamboo fiber, and kapok.…”

Bacterial cellulose‐modified castor oil‐based polyurethane sponge for hexavalent chromium removal

“…Currently, there has been an increase in interest in polyurethane foam (PUF) applications since it is a sorbent that represents an inexpensive and efficient means of separation and pre‐concentration, with increasingly versatile applications in the analysis of inorganic species 19–23 . The cellular structures, resilient characteristics, available surface area, excellent thermal and chemical stability, and low cost of the PUF in both foamed and micro spherical forms make it suitable as an excellent sorbent 24,25 . Furthermore, PUFs exhibit excellent hydrophobicity and essential oleophilic characteristics 20 …”
