Title: | Study of inhibition properties of some thiazole derivatives against copper corrosion | Authors: | Vaštag Đenđi Shaban Abdul Felhősi I |
Keywords: | corrosion, copper, thiazole derivatives | Issue Date: | 2009 | Journal: | XI YUCORR, International Conference Proceedings, YUCORR International Conference “Cooperation Of Researches Of Different Branches In The Fields Of Corrosion, Materials Protection And Environmental Protection”, Tara, 2009 | Abstract: | The inhibitor efficiency of some thiazole derivatives against copper corrosion in acidic sulfate solution were investigated using polarization and electrochemical impedance spectroscopy (EIS) methods. Protection efficiency of four organic molecules: 5-benzylidene-2,4-dioxotetrahydro-1,3-thiazole (5-BDT), 5-(4-isopropylbenzylidene)-2,4-dioxotetrahydro-1,3-thiazole (5-IPBDT), 5-(3-thenylidene)-2,4-dioxotetrahydro-1,3-thiazole (5-TDT) and 5-(3,4-dimetoxybenzylidene)-2,4-dioxotetrahydro-1,3-thiazole (5-MBDT) were investigated on copper electrode in 0.1moldm–3 Na2SO4 solution at pH=2.95. Polarization measurements indicates that all investigated thiazole derivatives could reduces the cathodic reaction rate on copper electrode surface in 0.1 mol dm–3 acidic Na2SO4 solution. In investigation range concentration 0.01mmoldm-3 has the best inhibitor efficiency in case of all investigated thiazole. The best protection is obtained in presence of 5-IPBDT derivatives. EIS results showed that investigated thiazole derivatives formed a film on copper surface which was able to protect copper against corrosion in acidic media. 5-IPBDT derivative only formed closely packed inhibitor film, which is able to protect copper surface during the time. | URI: | https://open.uns.ac.rs/handle/123456789/26883 | ISBN: | 978-86-82343-11-0 |
