The lead scientist at UBC and his team have developed a unique chemical product
Dr. Mohseni, the lead scientist at UBC, and his team have developed a unique silica-based material with a high capacity to absorb a range of perfluorooctane sulfonic acid from drinking water. The reusable material acts like a filter, trapping most harmful particles and then destroying them using a unique electrochemical and photochemical process developed by the researchers.
"Our adsorption medium can capture up to 99% of perfluorooctane sulfonic acid particles and can also be regenerated and potentially reused," says Dr. Mohseni. This means that when we remove perfluorooctanoic acid from these materials, we don't end up producing more highly toxic solid waste, which would be another major environmental challenge.".
Another study, by scientists at Arizona State University in the US, used microbes to break down PFAS.
The team, led by 2018 Stockholm Water Prize winner Bruce Rittman, used a specially modified membrane, known as MCfR, to cause a reaction in the water to attack the chemical composition of the PFAS particles it contains. The water is then treated with microbes in a special reactor (MBfR) to break down the remaining pollutant particles, which have one of the strongest carbon bonds in chemistry.
"We used MCfR to remove some to all of the fluorides, and then we gave the water containing those compounds to the microbes in the MBfR, and they did the job," Rittmann said.
ECHEMI --- The name originated from the abbreviation of “E-commerce of chemical”.
ECHEMI is a chemical supply chain service company headquartered in Hong Kong, providing chemical raw materials supply, research and analysis marketing, distribution, logistics, e-commerce, and after-sales services.
At present, the product ranges mainly cover paint & coating, food & nutrition, fine chemical, pharmaceutical, and rubber & plastic. In the next decade, ECHEMI will focus on supply chain services, resource optimization, and management efficiency, providing better products and services.
