Phase-selective cellulose nanofibril-based oil gelling agent for oil spill recovery

Abstract

A cost-effective powdery oil gelling agent based on cellulose nanofibrils was successfully fabricated and utilized to effectively remove an oil spill from the seawater surface.

Reusable Solid-form Phase-Selective Organogelators for Rapid and Efficient Remediation of Crude Oil Spill

“…Nowadays, there are some techniques as well as those combining the materials involved in oil pollutant cleanup, especially for marine oil spill remediation, which are commonly used in practice or can be available in the literature. These methods include physical methods based on the use of booms, skimmers, and adsorbents such as hydrophobic oleophilic sponges and activated carbons; chemical methods by using dispersants, herders, and solidifiers; as well as in situ burning or bioremediation with microbial − activities. However, the applications of these methods in real-life situations are usually subjected to some drawbacks.…”

A β-d-glucose pentaacetate derivative as an efficient phase selective gelator for oil spill recovery

“…Furthermore, the PB oil spill accident has raised public concerns about the environmental hazards caused by oil transportation. 3 Until today, many techniques, such as oil skimmers, anti-oil barriers, adsorbents, dispersants, microbial degradation, and oil gelling agents, have been widely employed to deal with oil spills. 4 Although these techniques have played an important part in practical applications, they have some limitations which cannot be ignored, such as the incomplete recovery of the oil skimmers and anti-oil barriers, high cost and limited adsorption capacity of adsorbents, possible secondary pollution of chemical dispersants, and long remediation time of biodegradation.…”
