Isotopes of Strontium: Properties and Applications

Handbook of Environmental Chemistry, 2019
The chapter gives an overview of properties and application of stable and radioactive isotopes of strontium. Natural strontium consists of the following four stable isotopes: 84Sr (0.56%), 86Sr (9.86%), 87Sr (7.00%), and 88Sr (82.58%). Among them, 87Sr is a radiogenic isotope being the decay product of the long-lived natural beta-emitting isotope 87Rb;

The strontium isotope fingerprint of phosphate rocks mining

Science of The Total Environment, 2022
High concentrations of metal(loid)s in phosphate rocks and wastewater associated with phosphate mining and fertilizer production operations pose potential contamination risks to water resources. Here, we propose using Sr isotopes as a tracer to determine possible water quality impacts induced from phosphate mining and fertilizers production.

Ground-state properties of strontium isotopes

Physical Review C, 1995
We present systematic constrained Hartree-Fock calculations of ground-state properties of even strontium isotopes ({ital A}=76--100) with the Skyrme interaction. Approximate projection of angular momentum is done after variation by explicit inclusion of the rotational energy {minus}{l_angle}{ital {cflx j}}{sup 2}{sub {ital x}}{r_angle}/J.

Strontium Isotopic Composition of Mid-Cretaceous Seawater

Science, 1994
The 87 Sr/ 86 Sr ratio in fish teeth separated from mid-Cretaceous marl and black shale from the northeastern Apennines and Venetian Alps (Italy) define three periods of low 87 Sr/ 86 Sr ratio at 121 to 124 million years ago (Ma), 110 to 115 Ma,

Isotope exchange of strontium and molybdate ions in strontium polymolybdates

Journal of Radioanalytical and Nuclear Chemistry, 2002
The heterogeneous isotopic exchange reactions in strontium polymolybdates of Sr2+ and MoO42- ions in the strontium nitrate and sodium molybdate solutions have been studied using 90Sr and 99Mo as tracers. Electrometric methods have been used to study the compositions of strontium molybdates obtained by adding strontium chloride to a progressively ...

Radiochemical separation of strontium by isotopic exchange

Talanta, 1967
Isotopic exchange has been used for the rapid separation of minute quantities of radio-strontium. A number of variables such as agitation time, concentration of strontium in both phases, mode of preparation and aging of the precipitates, were studied and optimized.
