Abstract

Abstract : An ultrastable zirconium phosphonate framework (SZ-7) exhibits superior Sr 2+ ion-exchange properties in 1 M NaOH solution with high adsorption capacity (183 mg g −1 ) and in-depth removal performance ( K d = 3.9 × 10 5 mL g −1 ). Abstract : We report here a distinct case of strontium removal under 1 M NaOH solution by an ultrastable crystalline zirconium phosphonate framework (SZ-7) with high adsorption capacity (183 mg g −1 ) and in-depth removal performance ( K d = 3.9 × 10 5 mL g −1 ), demonstrating the potential application of SZ-7 for 90 Sr removal in highly alkaline nuclear waste.
