Non-steady diffusion and adsorption of organic micropollutants in ion-exchange membranes: effect of the membrane thickness

open access: yesiScience, 2021
Summary: There is no efficient wastewater treatment solution for removing organic micropollutants (OMPs), which, therefore, are continuously introduced to the Earth's surface waters. This creates a severe risk to aquatic ecosystems and human health.
