Abstract :
Batch experiments were conducted to investigate the adsorption behavior of triclosan (TCS) at μg/L level in activated sludge. Effects of time, temperature, and MLSS on adsorption behavior were studied, and adsorption isotherm and thermodynamic parameters were studied as well. Sorption of TCS on the sludge was found to be physics-sorption, and partitioning played a significant role. TCS sorption process on sludge is basically exothermic and spontaneous. The study was meaningful for understanding the removal behavior of TCS in biological sewage treatment system.
