Elektrohemijsko ponašanje Cu24Zn5Al legure u rastvoru boraksa u prisustvu 1-fenil-5-merkapto-tetrazola
Univerzitet u Beogradu, Tehnički fakultet u Boru

Sažetak

U radu su predstavljeni rezultati ispitivanja uticaja inhibitora 1-fenil-5-merkapto-tetrazola (PMT)-a na elektrohemijsko ponašanje legure Cu24Zn5Al u rastvoru natrijum-tetraborata (boraksa). Polarizaciona merenja su vršena u rastvoru 0,1 mol/dm3 boraksa kome je dodavan inhibitor PMT različitih koncentracija (1·10-6 mol/dm3÷1·10-2 mol/dm3), kao i merenja nakon izlaganja elektrode rastvoru 1-fenil-5-merkapto-tetrazola u trajanju od 5, 15 i 60 min. Nađeno je da PMT pokazuje bolje inhibitorske osobine u slučajevima kada se elektroda Cu24Zn5Al izlaže izvesno vreme rastvoru PMT-a. Takođe, vršena su i polarizaciona merenja Cu24Zn5Al legure u prisustvu i odsustvu hloridnih jona (1·10-4 mol/dm3÷5·10-2 mol/dm3), sa (15 min) i bez prethodnog stajanja elektrode u rastvoru PMT-a. Adsorpcija 1-fenil-5-merkapto-tetrazola na površini Cu24Zn5Al elektrode pokorava se Lengmirovoj adsorpcionoj izotermi.
