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.
