Alkaline leaching is used for the extraction of uranium from rarely available carbonate ore. A hyperbranched cross-linked polymeric adsorbent (HCPA) was developed selective recovery uranium(VI) (U) real-life alkaline leach liquor. HCPA synthesized using free radical copolymerization acrylamide and N, N-methylene bis(acrylamide). In addition, potassium persulfate (as initiator) dodecanethiol brancher) were to transfer radicals faster chain formation smooth branching long-chain polymer....
In this work, bulk-liquid membrane (BLM) system is used to compare tri-n-butyl phosphate (TBP), tri-isoamyl (TiAP), and tris(2-ethylhexyl) (TEHP) for their relative ability co-extract U(VI) nitric acid from aqueous feed-phase into water strip-phase, through hydrocarbon membrane-phase. The kinetics of extraction modelled the model validated experiments. quantity which determines efficiency liquid emulsion (LEM) process rate acid. This in order TiAP>TEHP>TBP, indicating that TiAP most suitable...
Toennies , G. (Temple University School of Medicine, Philadelphia, Pa.), D. N. Das, and F. Feng . Pantothenate coenzyme A in bacterial growth. J. Bacteriol. 92: 707–713. 1966.—The effect environmental pantothenate levels on the growth Streptococcus faecalis 9790 was studied terms rate, depletion phenomena, cellular (CoA) content, differential rates wall membrane synthesis. Low concentrations yielded normal exponential curves up to peak turbidities which are a function concentration....
Although urine is the sample of choice for drug tests in racehorses, it rarely obtained following sudden death a racehorse on track while racing. The purpose this study was to demonstrate significance postmortem tissue samples as an alternative and blood equine analysis participating competitive race. Postmortem were frozen (−80°C) until analyzed. A 30–40-g portion each organ homogenized 0.1M phosphate buffer (pH 7.4), deproteinized, hydrolyzed with β-glucuronidase, extracted, screened by...
Fe(III) was extracted from mineral acids (HCl, HNO3, and H2SO4) into paraffin containing TBP n-decanol (solvating agent for Fe(III)-TBP complex), using a bulk liquid membrane extractor. Both the extraction equilibria kinetics of were determined. Rate by found to depend on acid in order HCl>HNO3≫H2SO4. co-extract with rate HNO3> H2SO4>HCl. The coextraction significantly enhanced presence Fe(III). A kinetic model predict concentration during developed validated.
A microprocedure potentially useful in serial determinations of phosphatides or lipid phosphorus is described, which liberation accomplished by heating bacterial specimens with aqueous methanol under pressure Teflon-capped tubes. Data are also presented suggest that the ease removal from cells a negative function their wall and membrane content.
Exploration of the specific role cystine in postexponential growth Streptococcus faecalis led to an inquiry into fate cellular coenzyme A (CoA) and acyl carrier protein (ACP), both which depend for their biosynthesis on pantothenate as precursors. In S. cells labeled by presence 14 C-pantothenate, label could be separated basis solubility at p H 2.1 two fractions sharply differing metabolic characteristics. The were not purified, but soluble C behaved analytically like CoA, insoluble was...
Numerical investigations have been carried out for a postulated enclosure fire scenario instigated due to methanol pool ignition in chemical cleaning facility. The under consideration is radiation-dominated and poses risk the nearby objects if appropriate safety requirements are not met. objective of current study was numerically evaluate provide recommendations prevent/minimize hazard. To do this, first modeled using finite volume method (FVM) based solver predict characteristics resulting...
This research work deals with an investigation on the reduction of mass transfer coefficient due to presence polymeric surfactant/ polycondensate layer in liquid membrane. Mo(VI) is chosen as target species which are be removed from feed solution using Bulk Liquid membrane (BLM) surfactant and extractant. Mathematical model developed for simulation kinetics extraction BLM. Study reveals that efficient extraction, stripping rate not at all desirable. Abil EM 90 found best suitable it has...
