Preparation of Cu(II)-imprinted PAAm/CS/zeolite composite cryogels (A) and the removal of template Cu(II) ions and partial hydrolysis of amide groups in PAAm (B) (reproduced with permission from Ref.

SEM micrographs of Cu(II)-imprinted PAAm/CS/zeolite composite cryogels after the elution of Cu(II) ions recorded perpendicular (C) and parallel (D) to the direction of freezing (reproduced with permission from Ref.

The kinetics performance of Cu(II)-imprinted PAAm/CS/zeolite composite cryogels in successive sorption and desorption of Cu(II) ions (E) (reproduced with permission of Romanian Academy Publishing House, the owner of the publishing rights, Ref. [23]). Optical images of Cu(II)-imprinted (denoted as II-CC15.H) and non-imprinted (denoted as NI-CC15.H) PAAm/CS/zeolite cryogels before and after HMIs sorption in multicomponent solutions (F) (reproduced with permission from Ref.
