Hydrocolloid-Stabilized Magnetite for Efficient Removal of Radioactive Phosphates

Abstract EN

Liquid radioactive waste is a common by-product when using radioactive isotopes in research and medicine.

Efficient remediation of such liquid waste is crucial for increasing safety during the necessary storage of the material.

Herein, we present a novel Gum Karaya stabilized magnetite for the efficient removal of radioactive phosphorus 32P from liquid radioactive waste.

This environmentally friendly material is well suited to be used as a nanohydrogel for the removal of liquid waste, which can then be stored in a smaller space and without the risk of the spills inherent to the initial liquid material.

The maximum adsorption capacity of the GK/M in this study was found to be 15.68 GBq/g.

We present a thorough morphological characterization of the synthesised GK/M, as well as a discussion of the possible phosphorus adsorption mechanisms.
