SNL-1, a highly selective inorganic crystalline ion exchange material for Sr2+ in acidic solutions
A new inorganic ion exchange material, called SNL-1, has been prepared at Sandia National Laboratories. Development samples of SNL-1 have been determined to have high selectivity for the adsorption of Sr from highly acidic solutions (1 M HNO3). This paper presents results obtained for the material in batch ion exchange tests conducted at various solution pH values and in the presence of a number of competing cations. Results from a continuous flow column ion exchange experiment are also presented.
