Formation of iron-containing composites

Resumo

The influence of corrosion inhibitors of different types on the formation of iron-containing composites in the presence of polyvinylpyrrolidone (PVP) and polyethyleneimine (PEI) was studied. It was shown that the composite containing sodium citrate is the most resistant to oxidation. To form the PVP‒Fe‒PEI composite in the medium containing a tea extract, no NaBH₄ is necessary to be added, whereas in the presence of P. adametzii fungal culture fluid permeate the reaction medium should contain an excess of NaBH4. For aldehyde functionalization of the PVP‒Fe‒PEI composite was activated with glutaraldehyde or dextran Т20 oxidized with NaIO₄.
