Abstract
Opušci cigareta predstavljaju jedan od najprisutnijih oblika otpada na svijetu. Obzirom da je u brojnim studijama dokazana njihova ekotoksičnost javlja se potreba za njihovim recikliranjem. Jedan od načina na koji se ova vrsta otpada može reciklirati je njihova primjena kod inhibicije korozije. U ovom radu prikazani su rezultati ispitivanja utjecaja ekstrakata opušaka (ekstrakt ostataka duhana i ekstrakt filtera) na koroziju elektrode od Cu10Ni legure u 3,5 % – tnoj otopini NaCl, pH 8, pri temperaturama: 12 °C, 20 °C i 25 °C. Za procjenu djelotvornosti inhibicije provedena su elektrokemijska mjerenja (mjerenje potencijala otvorenog strujnog kruga, metoda linearne polarizacije, elektrokemijska impedancijska spektroskopija i potenciodinamička polarizacijska metoda) i analiza površine elektrode (FTIR analiza, SEM analiza i goniometrija). Elektrokemijska mjerenja pokazala su veću inhibicijsku djelotvornost za ekstrakt filtera u odnosu na ekstrakt ostataka duhana (pri svim temperaturama). Maksimalna učinkovitost inhibicije postignuta je modifikacijom površine elektrode s ekstraktom filtera pri 12 °C, a iznosila je 96 % (potenciodinamaička polarizacijska metoda), odnosno 88 % (elektrokemijska impedancijska spektroskopija). Analiza površine potvrdila je prisutnost ekstrakata opušaka na površini elektrode.
Abstract (english)
Cigarette waste represent one of the most common forms of waste in the world. With the assessment that their ecotoxicity has been proven in numerous studies, there is a need for their recycling. One of the ways in which this type of waste can be recycled is their application in corrosion inhibition. This paper presents the results of testing the influence of cigarette waste extracts (tobacco residue extract and filter extract) on the corrosion of a Cu10Ni alloy electrode in a 3.5 % NaCl solution, pH 8, at temperatures: 12 °C, 20 °C and 25°C. To assess the effectiveness of inhibition, electrochemical measurements were carried out (measurement of the open circuit potential, linear polarization method, electrochemical impedance spectroscopy and potentiodynamic polarization method) and electrode surface analysis (FTIR analysis, SEM analysis and goniometry). Electrochemical measurements showed a higher inhibitory effectiveness of the filter extract compared to the tobacco residue extract (at all temperatures). The maximum inhibition efficiency was achieved by modifying the electrode surface with filter extract at 12 °C, and was 96 % (potentiodiamic polarization method) and 88 % (electrochemical impedance spectroscopy). Surface analysis confirmed the presence of cigarette waste extracts on the surface of the electrode.
