摘要: Abstract An alternative microwave-assisted hydrothermal route for the preparation of manganate nanoflowers under basic conditions has been proposed in view potential uses selective retention strontium from multicomponent aqueous streams. Based on combination such characterization techniques as Scanning and Transmission Electronic Microscopy, X-ray photoelectron spectroscopy, Diffraction, well taking advantage computer-aided structure simulation, homogeneous nanoflower morphology possessing a layered K+ compensating cations was evidenced corresponding to KMn4O8 chemical formula. The sample subsequently tested adsorption cesium by measuring individual isotherms single-solute solutions. material appeared towards against even solutions provided that concentration calcium remained low. This difference selectivity rationalized based Density Functional Theory (DFT) calculations energy direct calorimetry measurements enthalpy displacement cations.
