Abstract: This research is focused on the electrochemical synthesis and characterization of\npoly(methylene blue) (pMB). Two different carbon-based electrode substrates, basal plane\nhighly oriented pyrolytic graphite (HOPG) and pencil graphite electrode (PGE), have been\nmodified by conductive film of pMB. Electrochemical properties and nanomorphological\nchanges have been investigated by cyclic voltammetry and atomic force microscopy.\nImproved electroactivity of the modified electrodes (PGE/pMB and HOPG/pMB) towards\nsulfhydryl group has been observed and examined modified electrodes were researched for\ntheir possible application in electrochemical sensor for hydrogen sulfide in aqueous solutions.
