摘要:
In the present study, the adsorption behaviors of mordenite (a common
zeolite) with respect to Cu2+ and Ni2+ from aqueous solutions were
investigated. The sorption data followed the Freundlich and Langmuir
isotherms. The maximum sorption capacities were found to be 9.778
and 5.371 mg/g at pH 6, initial concentration of 40 mg/L and temperature
of 30°C for Cu2+ and Ni2+, respectively. The kinetic experimental
data fitted the pseudo-second order equation very well and the values
of rate constant of adsorption were evaluated. The Na-mordenite
could be used as low-cost sorbent to remove copper and nickel ions
from aqueous solutions.
