Recently,inorganic adsorbants have become important because of the great stability of high radiation by radio-active substances and at high temperature where the organic ion-exchange resins were not stable. The adsorption of Ca＾++ by the clay (called Kucha in Okinawa) which was found on the central part of Okinawa,was studied. Following subjects were described in this paper:1.Effects of sodium ion concentration and the heat processes on the dessolution of calcium ion 2.Relation between pH and adsorption of calcium ion 3.Determination of adsorption capacity of clay by using radio-active calcium (Ca-45). It was found that the adsorption capacity of clay was 0.40-0.56 (meq/5g)at theoptimum condition at pH 9.2.
