متن کاملBiotransformation of uranium and other actinides in radioactive wastes
Microorganisms affect the solubility, bioavailability, and mobility of actinides in radioactive wastes. Under appropriate conditions, actinides are solubilized or stabilized by the direct enzymatic or indirect nonenzymatic actions of microorganisms. Biotransformation of various forms of uranium (ionic, inorganic, and organic complexes) by aerobic and anaerobic microorganisms has been extensivel...
متن کاملVortex-Assisted Inverted Dispersive Liquid-Liquid Microextraction of Naproxen from Human Plasma and Its Determination by High-Performance Liquid Chromatography
Extraction and determination of naproxen from human plasma were performed using Vortex-Assisted Inverted Dispersive Liquid-Liquid MicroExtraction (VA−IDLLME) and High-Performance Liquid Chromatography (HPLC). The parameters affecting extraction recovery such as type and volume of extraction and disperser solvents, pH of sample solution, stirring rate, extraction time and salt addition were ...
متن کاملApplication of Microfunnel Magnetic Stirring Assisted Liquid-Liquid Micro-extraction Method for Pre-concentration and Determination of Silver Ion in Water Samples
In this research, a highly sensitive, selective, rapid and simple micro-funnel magnetic stirringassisted liquid–liquid microextraction (MF-MSA-LLME) method combined with flame atomic absorption spectrometry (FAAS) was introduced for the preconcentration, extraction, and measurement of trace amounts of silver ion. In this method 1-(2–Pyridylazo)-2-naphthol (PAN) and 1-octanol were used as chelat...
متن کاملOptimization Extraction of Terbium by Supported Liquid Membrane Using D2EHPA and TOPO
The extraction of Terbium (III)from aqueous nitrate solutions with a supported liquid membrane was investigated using a mixture of di-(2-ethylhexyl phosphoric acid (D2EHPA) and tri-octyl phosphine oxide (TOPO) with a molar ratio 1/0.4. The Hydrophobic Polyvinylidene Fluoride (PVDF) membrane was used as solid support. The sorption process followed pseudo-second-o...
