Abstract
The regeneration of activated carbon and hypercrosslinked polymers loa ded with simazine, chlorotoluron, isoproturon, atrazine and diuron usi ng low-temperature solvent stripping has been investigated. Pure ethan ol, azeotropic ethanol acetone, methanol and 1-propanol will efficient ly regenerate polymeric Hypersol-Macronet(TM) MN-200 at room temperatu re. Complete regeneration was achieved using about three bed volumes o f HPLC grade ethanol when operated in a mini-column. Excess ethanol is efficiently water washed prior to reuse. Chemviron F-400 is not effec tively regenerated using low-temperature solvent stripping. The advant ages of polymeric adsorbents are discussed.
