Study on Adsorptive Capacity of Cs+ in Several Mineral Materials

According to adsorptive capacity of few materials on Cs+, the synthetic zeolite(ZF) was selected to study adsorptive capacity for Cs+ in a few conditions including temperature, pH value, concentration and simulated groundwater with the intermittent method and offered some references for valued midlower radiowaste disposition. Experiment results show that adsorptive quantity of Cs+ on ZF increases and adsorptive ratio decreases with the increasing of Cs+ concentration in solution; and pH ranged from 5-9, its adsorptive capacityvaries a little and when pH=11 its adsorptive capacity fall down clearly; and in different simulated groundwater, its adsorptive capacity varies with chemical components of simulated groundwater. Moreover, adsorptive equilibrium time of ZF is about 10-15d.
