dc.description.abstractAn effective adsorbent for the removal of heavy metals was manufactured by immobilization of jujube powder. The adsorptions of Cd, Zn and Cu from aqueous solutions by jujube complex beads (Type-1 and Type-2) were studied in a batch adsorption system. The adsorption data were fitted well with the Langmuir isotherm models. The adsorption capacities () for Cd, Zn and Cu were 4.23, 2.93 and 3.64 mg/g in Type-1 and 1.24, 0.70 and 1.35 mg/g in Type-2 beads. The removal efficiencies of the Type-2 beads, with a larger unit surface area, were lower than those of the Type-1 due to part of the casein or cyclic AMP being destroyed during the drying process of the Type-1. These values for Type-1 beads were higher than those of all other adsorbents for each heavy metal. A comparison of the kinetic models on the overall adsorption rate showed that the adsorption system was best described by pseudo-firstorder kinetics. The removal efficiencies of Cd, Zn and Cu exhibited similar tendencies to those observed in the equilibrium tests. This indicates that the jujube complex beads developed in this study can be used as promising adsorbents for the removal of heavy metals from wastewater.-
