The silver nanostructures obtaining was investigated by electrochemical deposition from aqueous solutions (1–10) mM AgNO3 + 50 mМ NaPA) onto graphite substrate. The influence of the concentration of silver ions and cathode potential values in the range E = -0,2 – -1,0 V on surface filling degree and geometry of silver particles was (had been) studied.
The electrochemical co-deposition of palladium and gold on the glassy carbon surface from solutions of their salts in dimethylsulfoxide (DMSO) is studied. It is shown that the precipitate in the form of discrete sphere-like particles of 30...140nm, which are uniformly distributed on the substrate, is formed at concentrations of 0.004M PdCl2 + (0.002...0.004)M HAuCl4 + 0.05M Bu4NClO4, E = -0.3...-1.5V, at pulse electrolysis.
Evolution of swelling of gel-like strongly acidic resin and organic-inorganic composites based on this ion-exchanger was investigated. Non-aggregated nanoparticles of zirconium hydrophosphate were found to provide size invariability of the polymer pores, which contain functional groups (up to 20 nm), the nanoparticle aggregates squeeze these pores (down to 3 nm). Owing to this, the nanocomposite shows higher break-through capacity during removal of Ni2+ from water, than the sample modified only with aggregates.
