Adsorption isotherm models were utilized to describe the equilibrium isotherms and the isotherm constants were calculated. The sorption of ammonia follows Langmuir, Freundlich and Dubinin-Radushkevich (D-R) model isotherms. Langmuir constants Q(0) = 1.59 mmol/g and b = 28 L/mmol and Freundlich parameters 1/n = 0.72 and K-1 = 0.14 and D-R constants q(m) = 2.19 mmol/g, beta = 0.0146 mol(2)/kJ(2) and sorption energy E = 5.85 kJ/mol were evaluated. The MMZ displayed the main advantage of convenient separation compared with the present adsorption treatment processes.
