摘要: The characteristics of extracellular polymeric substances (EPSs) were compared for two different extraction methods and dissimilar sludge formation conditions (aerobic versus anaerobic). The measured characteristics included specific ultraviolet absorbance (SUVA) values, fluorescence excitation–emission matrices, molecular weight distributions, Fourier transform infrared (FT-IR) spectra, and the binding affinities for pyrene and Hg (II). The analyses demonstrated that the EPS extracted using cation exchange resin (CER) were …
