摘要
The regeneration of activated carbon and hypercrosslinked polymers loaded with simazine, chlorotoluron, isoproturon, atrazine and diuron using low-temperature solvent stripping has been investigated. Pure ethanol, azeotropic ethanol acetone, methanol and 1-propanol will efficiently regenerate polymeric Hypersol-Macronet(TM) MN-200 at room temperature. Complete regeneration was achieved using about three bed volumes of HPLC grade ethanol when operated in a mini-column. Excess ethanol is efficiently water washed prior to reuse. Chemviron F-400 is not effectively regenerated using low-temperature solvent stripping. The advantages of polymeric adsorbents are discussed.
