Abstract

The adsorption of triclosan (TCS) from aqueous media using tyre crumb rubber entrapped in calcium-alginate beads (TCR/CaAG beads) was investigated through batch experiments. In addition, the effect of solution pH on removal efficiency was also investigated. The maximum adsorption of TCS onto TCR/CaAG beads was approximately 83% at pH 7. The Langmuir and Freundlich adsorption isotherm models were used to depict the sorption process. Adsorbent reusability was investigated by performing a series of sorption/desorption experiments. The experimental results suggest that the TCR/CaAG beads are effective agents for the removal of TCS from an aqueous medium.
