Removal of micropollutants by fresh and colonized magnetic powdered activated carbon

This study evaluated the adsorption capacity and rate constants for 9 micropollutants (MP) on fresh and aged magnetic powdered activated carbon (MPAC) as a magnetically separable alternative to conventional PAC for drinking water treatment. MPAC with mass fractions of 10%, 38% and 54% maghemite nanoparticles were compared to bare PAC and pure maghemite in batch adsorption experiments. Pure maghemite alone did not adsorb significant amounts of MP...
