“…Scientists have studied the influence of the use of uraniumcontaining phosphate fertilizers in agriculture. The results indicate that uranium applied to soils for fertilization accumulates in the soils, and that a nearby water aquifer gets contaminated by a significant amount of uranium through leakage [25,45,46]. It is important to note that the production and use of uranium phosphate fertilizers induces adverse effects on humans through environmental bioaccumulation and food-chain contamination [47].…”

“…In a final experiment, the adsorption power of casein for uranium from uranium-rich natural spring water (Heinrichsquelle Nürtingen near Stuttgart, Germany) was tested. This water (the spring has been closed meanwhile) contains 371 μg L –1 uranium and possesses mineral contents which are unfavorable for uranium adsorption onto casein (carbonate concentration 3.02 g L –1 , Ca concentration 53.35 mg L –1 , pH 8.3).…”

Strong Uranium(VI) Binding onto Bovine Milk Proteins, Selected Protein Sequences, and Model Peptides

Hexavalent uranium is ubiquitous in the environment. In view of the chemical and radiochemical toxicity of uranium(VI), a good knowledge of its possible interactions in the environment is crucial. The aim of this work was to identify typical binding and sorption characteristics of uranium(VI) with both the pure bovine milk protein β-casein and diverse related protein mixtures (caseins, whey proteins). For comparison, selected model peptides representing the amino acid sequence 13–16 of β-casein and dephosphorylated β-casein were also studied. Complexation studies using potentiometric titration and time-resolved laser-induced fluorescence spectroscopy revealed that the phosphoryl-containing proteins form uranium(VI) complexes of higher stability than the structure-analog phosphoryl-free proteins. That is in agreement with the sorption experiments showing a significantly higher affinity of caseins toward uranium(VI) in comparison to whey proteins. On the other hand, the total sorption capacity of caseins is lower than that of whey proteins. The discussed binding behavior of milk proteins to uranium(VI) might open up interesting perspectives for sustainable techniques of uranium(VI) removal from aqueous solutions. This was further demonstrated by batch experiments on the removal of uranium(VI) from mineral water samples.

Increasing global phosphorus (P) needs and energy demands makes an efficient utilization of finite resources such as phosphate rock (PR) obligatory. The anticipated growth in nuclear energy may require the use of uranium (U) from unconventional resources such as PR as future raw material for nuclear reactor fuel. In parallel, increasing amounts of energy will be needed to process lower grade PR resources in order to satisfy rising phosphate fertilizer requirements for global food production. This work assesses the possibility of using the new generation of high temperature reactors (HTRs) for future energy neutral phosphate fertilizer production. Although advantages from an environmental and resource conserving point of view are obvious, challenges associated with the technical implementation and economic feasibility need to be addressed before implementation.
