【 摘 要 】

Environmental protection has increased over the years all over the world. In this investigation, the adsorption propertiesof live activated sludge (0.5 g and 1 g) for ivermectin, metamizol sodium and gentamicin sulfate were performed as abiosorbent. The biosorption of these veterinary pharmaceuticals were investigated in a batch system. The equilibriumadsorption data were described by Dubinin-Radushkevich (D-R) adsorption isotherm model. The adsorption equilibriumis attained within 20 min for ivermectin and gentamicin sulfate and 10 min for metamizol sodium. The estimated valuesof adsorption energy, Ea, calculated from the D-R isotherm, for all pharmaceuticals, ivermectin and live activated sludge(1.0 g) system were found to be 9,622 kJ mol-1 at room temperature, which implies that adsorption of ivermectin ontolive activated sludge (1.0 g) is by ion exchange.
