摘要

Liquid treatment filter with magnetite nanoparticles and corresponding methods. Liquid treatment filter comprising a support made of a polymeric material having at least one functional group of the group made up of carboxyl and thiol, loaded with SPION (SuperParamagnetic Iron Oxide Nanoparticles). The support is advantageously made of fibres of hydrolysed polyacrylonitrile of general formula wherein n has a value comprised between 0.01 and 1, and wherein the method for manufacturing comprises: [a] a step of electrospinning in which a solution of polyacrylonitrile is prepared in a solvent with a polyacrylonitrile content comprised between 5 and 80% by weight, with respect to the total weight of the solution, [b] a step of hydrolysis of the PAN fibres formed in step [a], and [c] a step of loading the fibres with SPION.
