(a,b) Fluorescence spectra obtained from the coated (top) side of Lew-RE in pristine state (a) and after the accelerated fouling test (b); (c) scores for PC1 and PC2 obtained from the EEMs obtained from the coated (top) side of pristine membranes and membranes after the accelerated fouling test; (d) scores for PC1 and PC2 obtained from the EEMs obtained from the coated (top) side of pristine membranes and membranes after the chemical cleaning; (e) scores for PC1 and PC2 obtained from the EEMs of pristine membranes, used membranes (after the IEMB experiments), and cleaned membranes after their use in a first batch of experiments.
