Abstract: Static adsorption of Strontium solution was studied in this experiment, with raw material powder of special geologicalcement used as the adsorbent. The results show that the maximum adsorption rateat equilibrium is 47.91%, the optimum adsorption time is 1.6 d, with the best performance of the cement under alkaline condition. The adsorption rate is proportional to the square of adsorption driving force. The adsorption of strontium ions by special geological cement is monolayer adsorption.
