Calcium zirconium CaZr₄P₆O₂₄ and magnesium zirconium MgZr₄P₆O₂₄ phosphates with NZP structure are promising materials for the safe disposal of high radioactive wastes. Herein, firstly the facile synthesis of calcium magnesium zirconium phosphate adsorbents transformed into MZr₄P₆O₂₄ (M: Ca, Mg) ceramic matrix as effective materials for radionuclides adsorption and immobilization was developed. The detailed analysis of phase composition, functional groups, elements content, surface morphology, texture and adsorption characteristics of prepared calcium magnesium zirconium phosphates were performed. It was shown that obtained samples were amorphous materials. The high efficacy (K _d > 10⁴cm³/g) of prepared adsorbents towards ¹³⁷Cs, ⁸⁵Sr, ⁶⁰Co radionuclides in the wide pH range of 4.0–10.0 was demonstrated. The formation of calcium zirconium CaZr₄P₆O₂₄ and magnesium zirconium MgZr₄P₆O₂₄phosphates with zirconia ZrO₂admixture during adsorbents calcination at 1000 °C was shown. The obtained results have high capabilities for the development of effective calcium magnesium zirconium phosphate adsorbents for radionuclides immobilization into MZr₄P₆O₂₄(M: Ca, Mg) ceramic matrix.
