Uptake of cesium and strontium radioisotopes onto pillared clays
Journal of Radioanalytical and Nuclear Chemistry, 1999 Abstract Pillared clays were characterised by thermal analysis and small-angle X-ray scattering. They were then examined for their ability to take up137Cs and90Sr/90Y isotopes as a function of concentration and competing cations (Na+, K+, NH4 +, Ca2+, Mg2+) in the concentration range 10−1 to 10−4 M. The radioisotope uptakes were quantified byK d (ml/g)

Determination of strontium radioisotopes in routine and emergency samples
Applied Radiation and Isotopes, 2022We present the radioanalytical strategies used for the determination of strontium radioisotopes in routine and emergency samples. While in routine monitoring, the main goal is to achieve limits of detection as low as possible. In emergency, priority is given to the rapid procurement of data about a contamination.

The uptake of caesium and strontium radioisotopes onto clays
Journal of Materials Chemistry, 2000Montmorillonite and illite clays have been examined for their ability to take up caesium and strontium radioisotopes from solution. Uptakes onto near homoionic Na, K, NH4, Mg, Ca, and Sr clays have been assessed by the construction of ion exchange isotherms. Effects of changes in concentration (total normality) and temperature have been assessed. Where

Determination of strontium radioisotopes in soils
Fresenius' Journal of Analytical Chemistry, 1991A method is proposed for determination of radiostrontium in soils which is based on selective strontium separation by liquid-liquid extraction with dicyclohexano-18-crown-6 in chloroform, loading of the extract on a thin-layer plate and TLC separation of strontium and yttrium radioisotopes using a circular procedure.

Preparation conditions of composite ion-exchanger based on stannic molybdophosphate (SMP) and poly-acrylamide (PAA) have been described. Batch distribution coefficients for some ions were investigated at 25 °C. Sodium ion exchange capacity and breakthrough curves of cesium and strontium ions have also been determined.

Abstract The removal and separation of Co-60, Sr-90, and Cs-137 radioisotopes from nitrate aqueous solutions were studied by competitive transport across cellulose triacetate plasticized membranes using organophosphorous acids compounds (D2EHPA, Cyanex 272, Cyanex 301 and Cyanex 302). Competitive transport of trace radionuclides ions from 0.10 M NaNO

This study aimed to reveal local structures of strontium (Sr) and cesium (Cs) adsorbed on clay minerals (vermiculite and montmorillonite), which suggests stabilities of the adsorbed species of 90Sr and 137Cs in the environment. Adsorption experiments to determine solid-water distribution, XRD for interlayer distances of the clay minerals, and EXAFS for

An amorphous, partially-reduced tin dioxide, having properties of an inorganic exchanger, was tested for application to fission product separations. Due to the good sorption of both strontium and barium the application of the exchanger to radiostrontium isolation from fission product mixtures is subject to important restrictions. An application to 90Sr
