Abstract
Natural zeolite collected from Ende-Flores Indonesia was characterized and activated with acid solution for Cr(VI) adsorption from aqueous solution. This natural zeolite is mainly composed of quartz and 50% mordenite. The kinetic adsorption modeling was fitted best with the pseudo-second-order model, whereas isotherm adsorption followed the Langmuir model with the maximum adsorption (Qmax) of NZ and ANZ are 0.189 mg/g and 1.040 mg/g. Moreover the ANZ was favorable for adsorption of Cr(VI) respectively.
