Abstract
|
|
|
The removal of Sr ion and Cs ion was investigated to evaluate adsorption properties by using SAN-Zeolite beads
immobilized with styrene acrylonitrile (SAN). The adsorption capacities increased with the decrease of SAN/zeolite ratio
(SAR) from 2.5 to 0.83. The relationship of adsorption capacity (qe) and SAR was described by experimental equation such as=0.9980). The adsorption kinetics of Sr ion and Cs ion with SAN-Zeolite beads were fitted
well by the pseudo-second-order model. The maximum adsorption capacities of Sr ion and Cs ion calculated from Langmuir isotherm model were 66.97 mg/g and 81.97 mg/g, respectively.
