The invention discloses a
temperature response type
europium ion imprinting
composite membrane preparation method and belongs to the technical field of environmental functional material preparation. Specifically, a
regenerated cellulose membrane is utilized as a supporting membrane,
graphene oxide and modified
silicon dioxide nanosphere are utilized as membrane preparing materials, an
europium ion is utilized as a formwork, acrylic
amide is utilized as a
functional monomer, N-
isopropyl acrylamide is utilized as a
temperature sensitive type
functional monomer,
ethylene glycol dimenthacrylate is utilized as a cross-linking agent, azodiisobutyronitrile is utilized as an initiator, a
composite membrane is prepared on the surface of the supporting membrane, a two-step temperature
polymerization method is utilized to prepare a
temperature response type
europium ion imprinting
composite membrane. A static adsorption experiment and a selective
permeation experiment are utilized to research adsorption balance,
adsorption kinetics, selective recognition and
europium ion separation performance of the prepared
temperature response type
europium ion imprinting composite membrane. Results show that the temperature
response type europium ion imprinting composite membrane prepared through the method disclosed by the invention has higher
specific adsorption capacity on europium ions and excellent europium ion recognition and separation performance under condition of 35 DEG C.
