Sorbent-based devices for the removal of spilled oil from water: a review

Swarming Magnetically Navigated Indigo-Based Hydrophobic Microrobots for Oil Removal

“…5 To avoid further adverse effects on the environment, mechanical recovery methods, such as booms, skimmers, and sorbents, are preferred. 6,7 Micro-and nanorobots are artificial devices that possess selfpropulsion abilities in a liquid environment. Based on the material and design of these devices, they can have several programmed functionalities; for example, they can communicate with each other, autonomously respond to environmental signals, transport materials to a specific location, and collect or degrade desired substances.…”

“…In general, there are four approaches to the removal of spilled oil: chemical methods, in situ burning, bioremediation, and mechanical recovery . To avoid further adverse effects on the environment, mechanical recovery methods, such as booms, skimmers, and sorbents, are preferred. , …”

Bentonite‐PDMS composite foams for oil spill recovery: Sorption performance and kinetics

“…Usually, freeze and supercritical dryings are the most commonly used methods for the preparation of cellulose aerogels 11 . Organo‐clay were widely studied as a great alternative to oil spill natural remedies, as demonstrated by Carmody et al 12 The main factors affecting sorbents selection are oil viscosity, surface roughness, the critical surface tension of the sorbents, the thickness of a floating layer, oil retention, contact angle, temperature, sorbent buoyancy, and strength 13 . In particular, the hydrophobicity of the absorbent material plays a fundamental role.…”

Blow Spinning of Polyimide/SiO2 Composite Fibrous Sponges with Excellent Adsorption Capacity and Recyclability

“…As the storage of nonrenewable energy on land gradually reaches a threshold and the demand for energy continues to grow, offshore oil and gas exploration has received more attention in recent years. − However, frequent leakage events during mining or transportation as well as the discharge of industrial wastewater containing organic solvents have caused considerable pollution to the marine ecosystem. − Therefore, a low-cost, efficient, and environmentally friendly treatment method of oily wastewater is still an urgent need. − At present, there are four main methods to deal with oily wastewater and leakage of organic liquid: (i) chemical treatment, (ii) bioremediation, (iii) combustion treatment, and (iv) physical recovery including skimmers or sorbents. − Among these, adsorbent materials have attracted more and more attention due to their ability to collect and remove organic solvents from the water surface without affecting the environment. , …”
