Recently, researchers from Imperial College London and the University of Toronto have developed a cost-effective sponge tool for the adsorption of crude oil in petroleum wastewater.
An article about the research was published in Nature - in the journal Nature Sustainability
.
In the process of oil production, the amount of oil waste water polluted by crude oil has always been very considerable, which also directly reflects the waste of oil and the pollution to the environment such as water bodies and discharge sites
.
According to the researchers, this is an innovative Surface Engineering Sponge (SEnS), which uses polyurethane foam as the material to organically combine surface chemistry, charge, and roughness to achieve the adsorption of crude oil droplets
.
And we know that although polyurethane foam itself has good oil absorption performance, usually this material can only show better working effect under certain acidic conditions
.
The research results show that the oil-absorbing sponge can quickly absorb crude oil droplets and crude oil droplets under the action of Lifshitz-van der waals and electrostatic attraction under the condition of working pH.
The removal efficiency is 95~99% under acidic, neutral and alkaline conditions
.
It is worth noting that the SEnS sponge also has good reusability
.
In addition, inspired by the adsorption properties of the sponge, the researchers are collaborating on bacteria removal from salt water, stating: "Although our sponge is designed to purify industrial wastewater, it can also be used in freshwater or marine conditions.
To improve future environmental problems caused by pollution leaks
.
At present, the research team has been modifying this sponge and trying to use it in industry.
Maybe we will have the opportunity to widely use this technology in industrial production in the near future
