Abstract [en]

reatment of AMD with alkaline waste materials such as LD-slag may cause increased mobilization of potentially toxic metals, particularly those that form oxyanions. Vanadium is one of them and it can reach up to 3 % (weight) in the LD-slag. In this report a multivariate approach was used to study the removal of primarily vanadium from AMD neutralized with LD-slag by adsorption to wood. Two of the most important factors for the adsorption were pH and contact time. Some 90 % removal of vanadium was obtained after a contact time of 7 days when 25 g L-1 saw dust was added to AMD neutralized with LD-slag.
