ABSTRACT
Weight loss ve loc i ty of exposed specimens
Thus ant i -bacterial a b i l i t y i s to be explained as follows. At the f i r s t stage SOB adheres to the surface of the specimens with Ni or NiO-based admixtures and produces H 2 S 0 4 ( e q . l ) . At the second stage H 2 S0 4 attacks insoluble Ni or NiO-based admixtures and ionizes the admixtures ( e q . 2 ) . Finally these products attack SOB and hinder the growth of SOB.
