Researchers at The University of Queensland have pioneered a simple, fast and effective technique to remove PFAS chemicals from water. \u00a0<\/span><\/span><\/span><\/span><\/p>\n

Using a magnet and a reusable absorption aid that they developed, polymer chemist <\/span>Dr Cheng Zhang<\/span><\/a> and PhD candidate <\/span>Xiao Tan<\/span><\/a> at the<\/span> Australian Institute for Bioengineering and Nanotechnology<\/span><\/a> have cleared 95 per cent of per- and polyfluoroalkyl substances (PFAS) from a small amount of contaminated water in under a minute.<\/span><\/span><\/span><\/span><\/p>\n

\u201cRemoving PFAS chemicals from contaminated waters is urgently needed to safeguard public and environmental health,\u201d Dr Zhang said.<\/span><\/span><\/span><\/span><\/p>\n

\u201cBut existing methods require machinery like pumps, take a lot of time and need their own power source.<\/span><\/span><\/span><\/span><\/p>\n

\u201cOur method shows it is possible to remove more of these chemicals in a way that is faster, cheaper, cleaner, and very simple.<\/span><\/span><\/span><\/span><\/p>\n

\u201cBecause our process does not need electricity, it can be used in remote and off-grid communities.\u201d \u00a0<\/span><\/span><\/span><\/span><\/p>\n

PFAS substances are synthetic compounds used in industry and consumer products since the 1950s, but they persist in the environment potentially leading to human health problems.<\/span><\/span><\/span><\/span><\/p>\n

The PFAS removal technique developed by Dr Zhang and Mr Tan involves treating contaminated water with a new solution, called a magnetic fluorinated polymer sorbent.<\/span><\/span><\/span><\/span><\/p>\n

\u201cThis solution that we developed coats the PFAS particles and then we can use a magnet to attract, isolate and remove them,\u201d Dr Zhang said. <\/span><\/span><\/span><\/span><\/p>\n

\u201cThe solution itself can be reused up to 10 times.<\/span><\/span><\/span><\/span><\/p>\n

\u201cOur team will now scale up the testing and we hope to have a commercially available product ready in the next three years.\u201d <\/span><\/span><\/span><\/span><\/p>\n
