Cleaning after large -scale oil flow is a long and expensive process, and damage to the coastal area is important. This is especially true to the Arctic Circle in the world where the newly opened sea lanes are increasing risk due to an increase in maritime traffic.
Currently, even in areas with a large population, it faces serious restrictions, such as low oil absorption, potential toxicity to marine organisms, and a slow repair process.
However, the progress of nanotechnology may provide a much more effective, safer and faster solution that is much more effective than the current method. It is a nano by a concordia -led researcher, according to a new paper in environmental science.
“Using nano materials as a response method has emerged as a promising and sustainable approach,” says Huifang Bi. Candidates for the Gina Cody Engineering and Computer Science Faculty of Architectural Engineering.
“In this paper, we integrate, review, and analyze 40-50 research on subjects to provide an important appearance of nanotechnology in the coastal oil flow reaction. Is identified as a gap between the use of nano materials and how to use it in the actual application.
She adds that she is widely studied to fight marine oil outflow, but she is particularly focused on restoring the coastline. She estimates that more than 90 % of the reviews are lab -based and not yet used in the field.
A field test is required to encourage the results
The unique characteristics seen in nanogeno use it for alleviation over various repair efforts. These include surface cleaning agents, distributed agents, adsorbors, and violet mediation. Each method has its own strengths and drawbacks that can be improved by using nano materials.
For example, replacing synthetic surfactants and organic solvents with bio -based nano materials can be very effective in removing oil and can produce toxic substances that may harm coastal biota. It is done.
Nanomaterials can also be used for dispersion agents. The clay -based nano material can stabilize oil particles with emulsion, and the bacteria that eat oil grow, and the area for accelerating oil loss increases. With aerogel and forms such as foams, nano materials can improve oil removal from water by absorption, adsorption, or combination, thanks to large surface areas and numerous adhesive sites.
Finally, it can also be used to accelerate violet mediation, a technique that uses microorganisms to break down harmless or harmless or harmless substances.
“These lab -based results are encouraging, but you need to be careful,” BI warns. “In order to minimize environmental risks and ensure the responsible application of nanotechnology in coastal oil flowing reactions, it is necessary to prioritize sustainable and environmentally friendly nano materials. You need to enlarge the test to measure in the field test.
According to Chunjiang AN, an associate professor in the same department, the appearance of nano materials as an oil flow correction tool is important.
“We are facing many new tasks, and the threat of oil flow affects both traditional and new areas, including the Arctic Circle,” he says. “It is necessary to cooperate with the government and the private sector to recognize these technologies so that they can be included in future correction guidelines.”
