Abstract
- A novel 3D potassium-containing zirconium fluorophosphonate K <subscript>2</subscript> Zr[CH <subscript>2</subscript> (PO <subscript>3</subscript> ) <subscript>2</subscript> ]F <subscript>2</subscript> (SZ-8) was successfully synthesized as single crystals via a solvothermal method using a mixture of nitric acid and potassium nitrate as mineralizers. SZ-8 can adsorb 110.6 and 57 mg g <superscript>-1</superscript> of Eu <superscript>3+</superscript> in pH 2 and pH 1 solutions respectively, highlighting its potential remediation for radionuclides with high charges. SZ-8 not only possesses superior Eu <superscript>3+</superscript> removal capacity under strongly acidic conditions, but also provides a universal synthesis strategy for crystalline zirconium phosphonates with inorganic counterions.
