A novel ionic liquid (IL) trioctyldodecyl phosphonium bis(2,4,4-trimethylpentyl)phosphinate was developed as a recovery agent for cobalt(II) and manganese(II) from spent lithium-ion batteries (LIBs). Absence of organic diluent provides an advantageous factor to IL-based extraction than the conventional one. Co(II) Mn(II) were extracted quantitatively aqueous phase IL phase. Extracted stripped u...

Polycrystalline samples of Ca3Al1 xZnxSb3, with x 1⁄4 0.00, 0.01, 0.02, and 0.05 were synthesized via a combined ball milling and hot pressing technique and the influence of zinc as a dopant on the thermoelectric properties was studied and compared to the previously reported transport properties of sodium-doped Ca3AlSb3. Consistent with the transport in the sodium-doped material, substitution o...

The elaboration of medicinal substances with high pharmacological activity is the primary task pharmaceutical industry. In this regard, plant raw materials as a source valuable biologically active are great interest. Kyrgyz camelthorn (Alhagi kirghisorum Schrenk) representing genus plants Fabaceae family growing in deserts. therapeutic properties desert characterized by hemostatic, wound-healin...

Chemical extractants used to measure labile soil metal must ideally select for and solubilise the labile fraction, with minimal solubilisation of non-labile metal. We assessed four extractants (0.43 M HNO3, 0.43 M CH3COOH, 0.05 M Na2H2EDTA and 1 M CaCl2) against these requirements. For soils contaminated by contrasting sources, we compared isotopically exchangeable Ni, Cu, Zn, Cd and Pb (EValue...

Organic-inorganic lead halide perovskites are promising optoelectronic materials resulting from their significant light absorption properties and unique long carrier dynamics, such as a long carrier lifetime, carrier diffusion length, and high carrier mobility. These advantageous properties have allowed for the utilization of lead halide perovskite materials in solar cells, LEDs, photodetectors...

A novel extractant beta-diketone-substituted diaza-18-crown-6 demonstrated very efficient extraction of Sr(2+) due to an intramolecular synergistic effect on the ionic liquid extraction system and recovery of Sr(2+) from the ionic liquid was successfully achieved under acidic conditions.

The effect of the surfactant template cetyltrimethylammonium bromide (CTAB) in MCM-41 on the adsorption of aniline was investigated. Various MCM-41 samples were prepared by controlling template removal using an extraction method. The samples were then used as adsorbents for the removal of aniline from aqueous solution. The results showed that the MCM-41 samples with the template partially remov...

2-Dodecylthiomethylpyridine (DTP) was newly synthesized to study its extraction properties for precious metals. DTP was a selective extractant for palladium(II) and gold(III) over base metals. The loading test for palladium(II) showed that one palladium ion reacted with one molecule of DTP. The extraction rate of palladium with DTP was measured using a Lewis-type transfer cell at 303 K. The ext...
