Removal of adsorbing estrogenic micropollutants by nanofiltration membranes:Part B-Model development

, 2013
Removal of estrone (E1) and estradiol (E2) by nanofiltration membranes at neutral pH is carried out both by size exclusion and adsorption. Size exclusion is dependent on the solute to pore radius ratio and the hormone-membrane affinity. It has been shown
