The electrodes were used in similar couples in this research, namely, Fe (anode) to Fe (cathode), Al (anode) to Al (cathode), and Cu (anode) to Cu (cathode). The samples were analyzed using spectrophotometric techniques UV/VIS and a colorimetric method. Higher removal efficiencies for color and COD were found at the current density of 0.025 A/cm2, i.e. Fe/Al/Cu electrodes gave 91, 62, and 51% in the COD removal and 93, 82, and 70% for color removal. Other parameters taken such as pH, electrolysis time, and the initial azo dye concentrations were also optimized at all of the electrodes. The decolorization and COD removal efficiencies were found decreased with increasing the initial dye concentration. Being simple and cost effective, this technique can be applicable for the treatment of real textile wastewater.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"59 5","pages":"661 - 669"},"PeriodicalIF":0.9,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49671088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The destruction of electrodes in the discharge and the introduction of Ag2S vapor into the interelectrode gap occurred due to the microexplosions of inhomogeneities on the working surfaces of polycrystalline electrodes (the formation of ectons) in order to synthesize thin films based on this compound on the surface of a dielectric substrate mounted near the electrodes. Numerically solving the Boltzmann kinetic equation for the electron energy distribution function, the temperature and the electron density in the discharge, the specific discharge power losses for the main electronic processes, and the rate constants of the electronic processes depending on the parameter E/N for the plasma of vapor-gas mixtures based on krypton and silver sulfide have been calculated.

The surface morphology and texture characterization of pure Ni coatings and Ni–V2O5 nanocomposite coatings were analyzed by spectroscopic techniques such as scanning electron microscopy (SEM) equipped with an attachment for energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) spectroscopy analyses. The SEM study confirmed surface morphology of the pure Ni coating was changed by the incorporation of V2O5 nanoparticles in the nickel metal matrix and chemical composition of all the coatings was determined by EDS. The XRD study proved highly corrosion resistant nanocomposites show preferred orientation towards (111) plane. The corrosion rate of all the coatings was investigated in a 3.5% corrosive medium using electrochemical techniques such as Tafel extrapolation and AC impedance. The coatings developed by PC showed an enhanced corrosion resistance behavior compared to that of the coatings developed by DC. The 0.125 g/L Ni–V2O5 nanocomposite coating obtained by PC showed more widened semicircles with a high Rp value and a more positive shift with high corrosion resistance during the AC impedance and Tafel extrapolation analyses respectively. The coatings developed by PC showed improved microhardness compare to that of the coatings developed by DC during microhardness testing of all studied coatings.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"59 5","pages":"569 - 581"},"PeriodicalIF":0.9,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49671087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
