Separation and Recovery of Uranium from Wastewater Using Sorbent Functionalized with Hydroxamic Acid
A newly developed hydroxamic acids functionalized acrylic based solid phase sorbent, named as poly-acryl hydroxamic acid (PHOA) is used as an extractant for the recovery of uranium from nuclear waste solution. Various parameters such as sorbent solubility in different medium, effect of various cations on U(VI) sorption, desorption performance of different eluents with respect to U(VI) sorption has been investigated in detail. U(VI) sorption behaviors of the sorbent were studied in different concentration of competitive ions such as Mg2+, Fe3+, and NO3- and it was found that the sorbent was capable of removing the U(VI) efficiently in the presence of high concentration of these ions.
