The potential of TiCT-KHPO and TiCT-chitosan in the efficient removal of cesium from nuclear wastewater.

TiCT is synthesized from TiAlC by two common methods, HF and HF in situ. The synthesis approach is very practical regarding the structure, morphology, space between layers, type and number of surface-active sites and its specific surface. XRD, SEM, EDS, FTIR and BET analyzes were used to investigate the structure, morphology, type and number of surface-active sites.

Experimental exploring of TiCT MXene for efficient and deep removal of magnesium in water sample.

In this work, the mechanism and behaviour of magnesium adsorption with TiCT adsorbent is investigated. TiCT was synthesized by selective exfoliation of Al layer from TiAlC using acidic solutions of HF 40% and 12 M LiF/ 9 M HCl. The effect of the synthesis method on the structure, the interlayer distance, the type and abundance of the functional groups, the bonds formed, the surface area and the volume of the formed cavities were evaluated by X-ray diffraction, scanning electron microscopy, Energy-dispersive X-ray spectroscopy, Brunauer-Emmett-Teller and fourier transform infrared analyses.

Modification of TiCT nanostructure with KHPO and chitosan for effective removal of strontium from nuclear waste.

Nanostructure titanium carbide MXene (TiCTx) was modified with KHPO and chitosan to effectively remove strontium from nuclear wastewater. Nuclear waste includes radionuclides of uranium, thorium, strontium, and cesium, which are classified depending on the concentration of radionuclides. Nuclear waste with a high strontium concentration is the production waste of radiopharmaceutical production centers.

Cerium(III) molybdate nanoparticles: Synthesis, characterization and radionuclides adsorption studies.

Cerium(III) molybdate nanostructure with average size about 40nm was prepared by adding cerium(III) chloride and ammonium molybdate solutions under varying conditions. The product was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA) and Brunauere Emmette Teller (BET) techniques. Ion exchange capacity of the sample for potassium ion and distribution coefficients (K(d)) for 23 metal ions were determined, the K(d) values for Tl(I), Pb(II), Th(IV), U(VI), and Cs(I) ions were found to be sufficiently high for their removal from various effluents.
