Abstract

In this study removal of haloacetonitriles from aqueous solution by employing a novel hybrid filtration process is investigated. The application potential of the oxidized multi-walled carbon nanotubes (O-MWCNTs) as adsorbent was investigated by evaluating the effect of different process parameters. Solution pH significantly affected the removal of DCAN (as a model of HANs) due to its strong effect on the charges of the adsorbent and the adsorbate. A maximum DOC removal of 98.7% for was achieved with 150 mg/L oxidized MWCNTs dosage and at a solution pH of 8. Finally, the nanofiltration technique using a PBS membrane was effectively employed to reject the wastewater pollutants (HANs) proprly.
