AZOT, FOSFOR VA KISLOROD TUTGAN YANGI (FKG2K-1) TURDAGI KARROZIYA INGIBITORNING SINTEZI
;
(FKG2K-1) kompozit ingibitor, guanidin nitrat, SEM, fosfat kislota, Lengmyur va Tyomkin izotermalari.Abstrak
Ushbu maqolada guanidin nitrat asosida sintezlangan yangi (FKG2K-1) kompozit ingibitorini 1 M HCl eritmasida uglerodli po‘lat konstruksiyalarini korroziyadan himoya qilish tadqiqoti olib borilgan. Bunda, tadqiqot ishida (FKG2K-1) kompozit ingibitorini turli xil konsentratsiya (250 mg/l, 500 mg/l, 750 mg/l va 1000 mg/l) va haroratlar (298 K va 323 K) da amaliy tajribalar o‘tkazildi. (FKG2K-1) kompozit ingibitorining po‘lat yuzasida adsorbsiyalanish Lengmyur va Tyomkin izotermalari va SEM analizlari bilan o‘rgnildi va tahlil qilindi. (FKG2K-1) kompozit ingibitorining samaradorligi 72.65% dan 92.68% ekanligi gravimetrik metodga asoslanib aniqlandi.
