Effective and energy-efficient separation of precious rare metals is very important for a variety advanced technologies. Liquid-liquid extraction (LLE) relatively less energy intensive technique, widely used in lanthanides, actinides, platinum group (PGMs). In LLE, the distribution an ion between aqueous phase organic determined by enthalpic (coordination interactions) entropic (fluid reorganiz...

Molecular dynamics simulations were performed on mixtures of N,N,N′,N′-tetra(2-ethylhexyl)diglycolamide (T2EHDGA) and 2-ethylhexylphosphonic acid mono(2-ethylhexyl) ester (HEHEHP) extractants in a dodecane-water system order to understand the organization interfacial behavior Actinide-Lanthanide Separation (ALSEP) process. The dynamic coordination environments these near interface investigated ...

Thirty-nine soils from northern New South Wales were used to examine the effects of phosphate buffer capacity on (i) the extraction of labile phosphate by four soil tests, (ii) the relationships between the four soil tests, and (iii) the critical level of each soil test required for near-maximum yield of wheat under field conditions. The results confirmed the principle, recently proposed by the...

Fe/Al-rich river sediments that were highly polluted with phosphorus (P) were used in tests to determine the optimum preparation techniques for measuring organic P (Po) using solution (31)P nuclear magnetic resonance spectroscopy ((31)P-NMR). The optimum pre-treatment, extraction time, sediment to solution ratio and sodium hydroxide-ethylenediaminetetraacetic acid (NaOH-EDTA) extractant solutio...

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...

Due to the content of phytosterols, extractive preparations Urtica dioica roots are able show antiandrogenic effect in case external therapy men and women with androgenic alopecia. Oil extracts (OE) characterized by several advantages when applied skin scalp compared water-alcohol extracts. For development OE technology from roots, it is important choose optimal extraction parameters, which bas...
