Published in 2022 at "Environmental science & technology"

DOI: 10.1021/acs.est.2c04658

Abstract: Nanofiltration (NF) membranes can retain micropollutants (MPs) to a large extent, even though adsorption into the membrane and gradual permeation result in breakthrough and incomplete removal. The permeation of MPs is investigated by examining the… read more here.
