- ... PURPOSE: Granular activated carbon (GAC) that is both an efficient polychlorinated biphenyl (PCB) adsorbent and a good growth support for microorganisms is considered suitable for in situ remediation of PCB-contaminated aquatic sediment. Here, the potential competition between biofilm formation and PCB (Aroclor 1260) adsorption on GAC in a PCB-contaminated aquatic sediment was investigated. MATERI ...

- ... Three commercial granular activated carbons (GACs) were studied at laboratory scale with a view to the combined adsorption and biodegradation of PCBs in aquatic sediment. The three GACs, with contrasting physico–chemical characteristics, all show a high adsorption of PCBs and are thus capable of reducing aqueous pollutant concentrations. After a one-month incubation with ‘Aroclor 1242’-spiked sedi ...
