Keywords:geopolymer, distribution coefficient

By classifying distribution coefficient of metal ions on a geopolymer with the element characteristics, it was indicated that the coefficient hardly depended on the element features in comparison with that of a cement material. This shows that the geopolymer can be more generally used to solidify radioactive waste than the cement.
