Abstract. The interacting mechanisms of metallic cations (Zn2+ and Co2+) to active chemical groups on the extracellular polymeric substances (EPS) of the aerobic granules, including loosely bound EPS (LB-EPS) and tightly bound EPS (TB-EPS), were examined by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) spectroscopy. For Zn2+ and Co2+, LB-EPS showed stronger bi…
BACKGROUND: Acrylamide has attracted worldwide concern due to its neurotoxicity, genotoxicity, reproductive–development toxicity. It is necessary to develop an accurate and reliable analytical method to prevent the harm on the human health. RESULTS: In this study, a sensitive and fast analytical method of direct competitive biomimetic enzyme-linked immunosorbent assay(BELISA)wasdevelopedusin…
