The physico-chemical proprieties of Zr/Ti-PILC have been optimized with pillarization processes and Cu(II), Ni(II) and Co(II) adsorption from aqueous solution has been carried out, with maximum adsorption values of 8.85, 8.30 and 7.78 x10-1 mmol g-1, respectively. The Langmuir, Freundlich and Temkin adsorption isotherm models have been applied to fit the experimental data with a linear regression process. The energetic effect caused by metal interaction was determined through 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.porAcesso AbertoAdsorçãoTermodinâmicaMetaisProcesso físico-químicoMonte Alegre - PAPará - EstadoAmazônia brasileiraZR/TI-PILCPropriedades físico-químicasAplicação de Zr/Ti-PILC no processo de adsorção de Cu(II), Co(II) e Ni(II) utilizando modelos físico-químicos de adsorção e termodinâmica do processoApplication of Zr/Ti-PILC in the adsorption process of Cu(II), Co(II) and Ni(II) using adsorption physico-chemical models and thermodinamics of the processArtigo de Periódico
