Summary: A solvent extraction method has been developed to separate tetravalent selenium and tetravalent tellurium from a nitric acid medium. Under optimum conditions, the extraction of Se(IV) was over 98%, with a separation factor of 201.7. Using 2.0 M HNO3 and 0.06 M CYANEX 301 as the optimum acid concentration allows for effective and selective extraction and separation of Se(IV) and Te(IV).

Summary: This study developed a mathematical model based on response surface methodology (RSM) for liquid-liquid extraction and separation of Selenium and Tellurium from aqueous nitric acid solution using Cyanex 301 as an organic extractant. The model identified with central composite design (CCD) examined the impacts of nitric acid concentration, Cyanex 301 concentration, and extraction temperature on the extraction percentage of Se(IV) and Te(IV). The results indicated that Cyanex 301 concentration was the most crucial variable and an optimal condition for selective extraction was achieved at specific concentrations and temperature, proving the effectiveness of the model in optimizing the extraction conditions.

Summary: This study investigated the solvent extraction of different groups of rare earth elements (LREE, MREE, and HREE) from a chloride medium using a mixture of Cyanex 572 and Alamine 336. The results showed that the addition of Alamine 336 to Cyanex 572 increased the extraction efficiency of LREEs and MREEs. The analysis suggested that Alamine 336 acted as a proton ion extractor and phase modifier for REECl2+ complexes.

Summary: This article describes the synthesis, characterization, and reactivity of pyrrole-based Ti(III) and Ti(IV) PNP pincer complexes. The Ti(IV) complex [Ti(PNPiPr)(Cl)(3)] was obtained by reacting [P(NH)P-iPr] with [TiCl4(THF)(2)] in the presence of NEt3. Insertion of the ketone into the Ti(IV)-P bond resulted in the formation of a tridendate PNO-ligand. Complex [Ti(PNP-iPr)(Cl)(2)(THF)] was obtained by treating [TiCl3(THF)(3)] with the lithium salt of [P(NH)P-iPr].

Summary: The study focused on investigating the corrosion behavior of refractories during the aluminothermic reduction of Ti-bearing blast-furnace slag (TBFS) and determining the most suitable refractories for this process. It was found that alumina and magnesia bricks were more effective in obtaining Ti-Si-Al alloy and reducing mass loss compared to carbon bricks. Additionally, the study revealed that the corrosion of alumina and magnesia bricks increased with the addition of CaO, with alumina bricks showing more severe corrosion compared to magnesia bricks. The highest extraction ratio of Ti (99.85%) was achieved when using magnesia bricks, making them the optimal refractory for the process.

Summary: The extraction of lanthanides using the sulfur donor ligand Cyanex 301 showed a change in coordination mode between light lanthanides (La-Eu) and heavy lanthanides (Gd-Lu). Despite no significant variation in slope dependence for actinides and lanthanides as a function of pC(H+), higher nitrate concentrations were found to suppress the formation of outer sphere complexes, enhancing lanthanide extraction. This suggests that the actinides form inner sphere complexes, indicating differences in the chemistry of actinides and lanthanides throughout the actinide series.

Summary: In this study, the separation of Hf(IV) over Zr(IV) from the highly concentrated aqueous feed by solvent extraction with ionic liquid Aliquat 336 was investigated, and it was found that thiocyanate forms of the ionic liquid dissolved in amyl acetate were more conducive to selective extraction of Hf(IV). The optimal extraction efficiency of Hf(IV) could be up to 94.5% under the selected conditions, with a separation factor of 19.4.
