Abstract:

An electrokinetic process to remove heavy metals and polycyclic arom. hydrocarbons (PAH) from fine-grained sludges for soil reclamation was developed. Results of the elimination of Cd from a model sludge showed a degree of purifn. of >98% if a cationic exchanger and/or a chelate exchanger was used. The degree of purifn. for phenanthrene removal from sludges was 72.5 and 70.5%, resp., if a non-ionic tenside and 2-propanol, as dissolving intermediary in the scavenging liq., were used.
