Sorption of strontium on the composite sorbent based on cellulose and hydrated antimony pentoxide

Хімія, фізика та технологія поверхні, 2017
In this study cellulose-inorganic sorbents based on bleached cotton fibres and hydrated antimony pentoxide were prepared and used for strontium ions sorption from model aqueous solutions. The adsorption of strontium ions was determined by the radiotracer

Seaweed against strontium and preussian blue against cesium

Rangifer, 1988
The fact that alginates bind strontium and cyanates bind cesium and are capable of removing these elements from living organisms is scientifically verified. Zeolites offer another possibility for exchange of these ions.

The use of stable Cs and Sr as proxies for the estimation of radionuclide soil-plant transfer factors [PDF]

Ядерна фізика та енергетика
Transfer factors are key inputs for modelling the transport of radionuclides in the environment and for assessment of risk to humans and wildlife. However, for many combinations of soil conditions, plant species (products), and radionuclides, such ...

A novel hybrid material with calcium and strontium release capability [PDF]

, 2012
The preparation of PDMS–TEOS–CaO hybrid materials by sol–gel techniques has been widely described in previous works. Calcium nitrate is the most common source of calcium used in these preparations.

Structure and properties of strontium-doped phosphate-based glasses [PDF]

, 2008
Owing to similarity in both ionic size and polarity, strontium (Sr2+) is known to behave in a comparable way to calcium (Ca2+), and its role in bone metabolism has been well documented as both anti-resorptive and bone forming.

Strontium-Substituted α‑TCP: Structure, Stability, and Reactivity in Solution

, 2023
α-Tricalcium phosphate (α-TCP) is widely used as a component of bone cements, and many efforts have been made to dope it with strontium ion (Sr), which is known for its beneficial role in bone tissue.

Study of the detection efficiency of a surface contamination monitor according to the distance and the surface emission rate

Saúde & Tecnologia, 2015
Introduction – A radioactive contamination needs to be quantified in case it eventually occurs. Therefore it is necessary to ensure that the operating conditions of a surface contamination monitor are characterized by determining its detection efficiency.
