ABSTRACT: The aim of this paper is the assessment of Donnan
dialysis coupled to adsorption process for the removal of chromium from aqueous
solutions. This study was conducted in order to benefit from each process, and
it was an original and new combination. The coupling was a solution to improve
the contact time and the amount of chromium (VI) removed. The coupling was
successfully performed with 90% of chromium (VI) removed after 6 hours.
