One step deposition method for the synthesis of a nanocpmposite membrane based on reduced graphene oxide/zeolite 3A for adsorption of metal ions with enhanced antibacterial properties

In this work, we present the development of a nanocomposite membrane based on reduced graphene oxide (r-GO) and zeolite 3A. This innovative nanotechnology embraces the concepts of water reuse and water efficiency, with an environmentally friendly, energy-efficient and rapid development, for wastewater and industrial wastewater treatment. The synthesis involves with a one-step deposition by vacuum filtration on a nylon substrate, of a homogeneous mixture of graphene oxide and zeolite 3A powder, then reduced to r-GO with a hydrazine treatment. The bactericidal properties of the membrane were tested in liquid medium, against four multi-drug resistant clinical isolates species (Gram-positive: Staphylococcus aureus Sa2 and Gram-negative: Escherichia coli APN1, Pseudomonas aeruginosa PaPh32 and AC12a).
