Washington D.C., Aug. 19 -- : A team of scientists from Uppsala and Dhaka University, has shown that a locally grown and previously unexploited green macro algae species could be used to extract cellulose nanofibers, which can then be formed into paper sheets with tailored pore size that are utilised for point-of-use water treatment.
The study was published in the journal 'ACS Sustainable Chemistry & Engineering.'
"Pithophora algae have been largely overlooked in the past as a valuable raw material. It is with great satisfaction that we can now document excellent pathogen removal clearance for both water-borne bacteria and viruses with efficiency above 99.999 per cent. It can purify even the smallest virus particles of 27-28 nanometers", ...
