Abstract

In this
study, sorption potential of anion exchange resin (Lewatit Monoplus M600) to
remove sulphate from real wastewater was investigated. Kinetic studies were
performed in batch experiments. A comparison of kinetic models applied to the
sorption of sulphate onto resin was evaluated for the "infinite solution volume model" and
"unreacted core model". Rate-determining step is the liquid film control
step of the unreacted core model. When pH values increased above 9, more than
80% sulphate removal was observed. Column sorption-elution experiments were
performed for the removal of the sulphate from the wastewater by resin. The
Thomas and the Yoon-Nelson models were applied to experimental data to
determine the characteristic column parameters.

Keywords
