Method for producing ferromagnetic nanocomposite chitosan/poly(asparagate)/ Fesub3/subOsub4 /subo with negative surface charge

摘要

the object of the application is the way to receive ferrimagnetycznego nanokompozytu chitosan / poly (aspartate, sodium) / fe3o4 of negative surface charge.fe3o4 containing nanoparticles of size from 10 to 100 nm.this is,that to the transparent for microwaves is aqueous solutions of iron (ii) salt and iron (iii) and intensive mixing and by applying microwave radiation.the following substance podwyu017cszaju0105cu0105 ph mixture of organic bases and / or inorganic, until black colouring solutionthen the following composition containing chitosan dissolved in an aqueous organic acid or amino acid.polyethylene and poly (aspartate, sodium) and all undergo cross-linking reaction using microwave radiation, and then is separated from the solution nanokompozyt poreakcyjnego.
