Abstract:
A process for removing algae-associated odorant from fresh water comprising the steps of:(a) contacting fresh water having an algae-associated odorant with cyclodextrin cross-linked to a water soluble polymer to form a first sorbent/mobile phase admixture;(b) maintaining said contact for a time period sufficient for the cross-linked cyclodextriu to sorb the algae-associated odorant to form a second sorbent/mobile phase admixture comprising algae-associated odorant-bound cross-linked cyclodextrin and treated water having a diminished amount of the algae-associated odorant; and(c) separating the odorant-bound cross-linked cyclodextrin from the treated water to provide algae-associated odorant-depleted fresh water.
