Abstract
Natural kaoline has relatively low cation exchange capacity, but the capacity cant be increased remarkably by the treatment with sodium hydroxide solution.
Clays are dispersed in water as very small particles, so it is too difficult to separate them from the water. A kaoline tablet was newly prepared to prevent the dispersion by binding with cellulose. Strontium was used as an adsorbate in packed column operation, because the author examined already that the kaoline had a selectivity to strontium than cesium. It was the most serious function to select the flow-rate of the solution in the column operation. In a low flow rate, the capacity of 100200 meq/100g was obtained for strontium.
Cellulose did not affect the adsorption characteristics of strontium, however the kaolinite tablet was swelled and deformed under the condition of a strong irradiation or acidity.
