The present investigation was carried out about the corrosion inhibition and adsorption behavior of Neem and Hibiscus, as a green inhibitor of Zinc corrosion in acidic mediated of corrosion causing soil microbes by using weight loss and thermodynamic studies. Even analyze the quantitatively and qualitatively biochemical substances present in Neem and Hibiscus leaves of aqueous and ethanol extract which act as an anticorrosive agent of metallic and non-metallic substances in acidified soil. Ethanol and aqueous extract of Neem and Hibiscus leave extract showed the strong antimicrobial activity against soil microbes such as S.aureus, Streptococcus, B. subtitles, Lactobacillus, Proteus, Corynebacterium, Pseudomonas, A.niger, Mucor and Desulphovibro sp. Langmuir and Freundlich, Temkin and Florry-Huggins models are employed to analysis adsorption occurred in the experimental data of adsorption isotherms.
