The different values of pH, EPS dosage, initial uranium concentration, dialysis temperature and other factors, were investigated of anaerobic sludge extracellular polymer (EPS) on U (VI) in wastewater by adsorption effect. The results show that, the best pH of EPS adsorption of uranium is 6, when the initial concentration of uranium is 20mg/L, EPS dosage is 56.1 g/L, the removal rate can reach 98.3%. The maxim...
