Sažetak

U ovom radu ispitivana je mogućnost zaštite bakra od korozije u kiseloj sredini primenom inhibitora. Testirane su inhibitorske osobine 5-(4' -izopropilbenziliden)-2,4-dioksotetra-hidro-1,3-tiazola, (IPBDT) na koroziju bakra u kiseloj sulfatnoj sredini (0,1 moldm-3 Na2SO4, pH=2). Primenom potenciostatskih polarizacionih merenja određena je inhibitorska efikasnost IPBDT-a u funkciji koncentracije. Nađeno je, da u ispitivanom opsegu koncentracije inhibitorska efikasnosnost IPBDT-a raste sa porastom njegove koncentracije. Dobijeni rezultati takođe pokazuju da IPBDT derivat deluje kao mešoviti inhibitor na koroziju bakra u kiseloj sredini u toku koje se on adsorbuje na površinu metala po mehanizmu Langmirove izoterme.
