Abstract: The montmorillonite clay sample from amazon region, Par State, Brazil, was used for intercalation process with pyridine (P) and organofunctionalization with 3-aminopropyltriethoxysilane (APS). The montmorillonite-P/APS shows variation of d(001) values, by changing d(001) from 1.15 to 2.10 mm. The original and modified samples were used for mercury cation adsorption from aqueous solution at room temperature and pH 6.0. The energetic effect caused by mercury cation adsorption was deter-mined though calorimetric titration at the solid-liquid interface and gave a net thermal effect that enabled the calculation of the exothermic values and the equilibrium constant.
