AB The addition of carbon nanotubes to improves the removal and adsorptionof endocrine disrupting micropollutants (bisphenol A and nonylphenol). Increasingthe SWCNT (single walled carbon nanotubes) content increases removal anddiminishes reversible and irreversible fouling.The isoelectric point of the SWCNT containing membranes decreases whenthe content of nanotubes increases with more negative charges at alkaline pH.Because, the nanotube loaded membranes are also less hydrophilic and bisphenoland nonylphenol are hydrophobous, adsorption plays a key role in the removal ofmicropollutants. An increase in the transmembrane applied pressure decreases theremoval and more steeply for the membranes containing more SWCNT.Higher porosities, leading to higher water permeabilities, are also obtainedfor more loaded membranes. Too high SWCNT contents lead to a saturation anddecrease of removal probably because high porosities lead to a decrease inadsorption due to both a decrease in the available surface and a sweeping action ofconvection through the membrane.
