Korozija metala aluminijuma na pH 10 je kontrolisana dikarboksilnim kiselinama kao što su oksalna kiselina (OA) i adipinska kiselina (AA). Efikasnost inhibicije (IE) je određena klasičnom metodom gubitka težine. Maksimalna efikasnost inhibicije (IE) koju nude sistem oksalne kiseline (OA) i adipinske kiseline (AA) 250 ppm i Zn2+ 50 ppm iznosi 88% i 96%. Za određivanje vrednosti linearne polarizacione otpornosti (LPR) i struje korozije (Icorr), korišćena je potenciodinamička studija polarizacije.Reference
