Microwave-Assisted Hydrothermal Synthesis of Agglomerated Spherical Zirconium Phosphate for Removal of Cs+ and Sr2+ Ions from Aqueous System
Abstract
Crystalline and agglomerated spherical alpha zirconium phosphate nanoparticles hereafter α-ZrP were synthesized by a facile and rapid microwave-hydrothermal (MW-HT) approach within 30 min at 120 °C in the absence of any complexing or structure directing agent (SDA). The material was characterized by Fourier-transform infrared (FT-IR), powdered X-ray diffraction (PXRD), scanning electron microscopy (SEM), energy dispersive spectroscopic analysis (EDS) and surface area analysis (BET). It crystallizes in the monoclinic P121/n1 space group with the following cell parameters: a = 5.288, b = 9.174, c = 15.384 Å and β = 102.384. Crystallite sizes in the range 3–4 nm evaluated using Scherer equation were obtained for α-ZrP. Ion exchange performance of α-ZrP towards removal of Cs+ and Sr2+ ions was examined under noncompetitive batch conditions. Distribution studies indicate higher selectivity of α-ZrP towards Sr2+ uptake (Kd ca. 4.3 × 104) in comparison with Cs+ (Kd ca. 2.4 × 103). This study suggested to agglomerated α-ZrP as potential adsorbent for the removal of radioactive Sr2+ from acidic wastewater.
