Abstract: The adsorption behaviour of 90 Sr on porous borosilicate glass by statical method is studied. The adsorption ratio and adsorption balance time of 90 Sr on porous borosilicate glass are determined. The influence of such factors as adsorbent partical size, solid liquid proportion, pH value and the concentration of strontium carrier solution on adsorption ratio is observed. The adsorption capability and the Freundlich adsorption isotherms are reported. The results indicate that 90 Sr can be effectively adsorbed by porous borosilicate glass.
