Organic compounds bearing heteroatoms with high electron density, such as phosphor, sulfur, nitrogen, oxygen or those containing multiple bonds which are considered as adsorption centers, are effective as corrosion inhibitor [7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19].
The shape of adsorption isotherms indicated a presence of two types of adsorption centers at lower temperatures of measurements.
Moreover, 3D mesopore cage adsorbents are reversible, offering potential for multiple adsorption assays.
Application of the Freundlich equation suggests that adsorption energy exponentially decreases on completion of the adsorption centers of sorbent.
Its active centers are superficial hydroxyl groups, capable of dissociating and forming positively and (or) negatively charged adsorption centers [8].
The FTIR results show that nitrogen atoms act as adsorption centers.
Functional electronegative groups and p-electron in conjugated double or triple bonds, are the major adsorption centers.
Simulations yield, for both molecular configurations, multiple adsorption maxima, which are located for the blue marked enantiomer at φ max, blue = 42°, 57°, 102°, 161°, and 178°.
The proposed model includes multiple producers, distribution centers, customers, collecting centers, recovery centers, and recycling centers.
