4 Conclusions
A membrane adsorber with HP-HKUST-1 has been fabricated by flowing
synthesis for CR and MB adsorption. The mesopores of the HP-HKUST-1 can
increase the adsorption active sites and enhanced mass transfer can be
achieved in the confined space of the membrane pores during the
adsorption process under the flow-through mode. The structures of the
membrane adsorber have been characterized by XRD, XPS, FTIR, SEM, TEM
and BET, which determined the successful immobilization of HP-HKUST-1 in
membrane pores. Compared with the HKUST-1 powder, the adsorption
capacity and rate for these two dyes can be increased several times by
membrane adsorber. The membrane adsorber with HP-HKUST-1 immobilized in
membrane pores also shows a remarkable repeatability and has good
potential in industrial application.
