Nanoarchitectonics with hybrid −O–(PO2)3–O−⋯+NH3–SiO⋯Fe3O4 magnetite particles as a decorporating agent for the removal of uranyl from blood serum

Abstract

We have developed hybrid ⁻O–(PO₂)₃–O⁻⋯⁺NH₃–SiO⋯Fe₃O₄ magnetite particles for the removal of uranyl ions from water as well as blood serum. Pure Fe₃O₄ particles have absorption properties towards uranyl in water, but very negligible interaction properties in blood serum. However, our developed hybrid has strong absorption properties with uranyl ions in water as well as blood serum. The absorption percentages of uranyl over 10 mg of pure Fe₃O₄ and hybrid Fe₃O₄ are 2.06, and 66%, respectively in blood serum. The absorption properties of the hybrid are related to magnetic particles capped with NH₂ and ⁻O–(PO₂)₃–O⁻groups, as well as porous –SiO– over the magnetic particles. In blood serum, there are many components such as proteins and ions such as Na⁺, K⁺, Cl⁻, HPO₄²⁻, and HCO₃¹⁻, that can influence the absorption properties of magnetic particles towards uranyl, whereas these do not influence hybrid particles.
