Abstract / Full Text

Poly-N,N-diallylmorpholinium bromide is synthesized and characterized using the methods of IR and NMR spectroscopy. The surface modification of MA-41 industrial heterogeneous membranes (Russia) by this polyelectrolyte is carried out from an equivalent mixture of N-methylpyrrolidone and anhydrous formic acid and also from aqueous solutions. The electrochemical characteristics of the modified membranes are studied on the setup with a rotating membrane disk. It is found that the reaction of water dissociation on modified membranes occurs less intensively than on the initial membrane and the main mass transport mechanism in the superlimiting current modes in systems with modified membranes is electroconvection.
