extractant การใช้

• It is used as an extractant and an oxygenate gasoline additive.
• The contained extractant is supposed to enhance the capacity of the resin particles.
• These might be remedied by choosing the proper particle-extractant-system.
• The Morenci Jameson Cell consistently recovered over 82 % of the organic extractant.
• A butanol permeable membrane is placed in between the fermentation broth and extractant solvents.
• The packed bed is then rinsed with the liquid extractant until inlet and outlet concentrations are the same.
• The interior is completely filled with extractant and thus increases the impregnation capacity as compared to classical SIRs.
• Solvent Impregnated Resins ( SIRs ) are porous resin particles, which contain an additional liquid extractant inside the porous matrix.
• The extractant, including the host, must be substantially insoluble in the processed aqueous solutions to avoid being washed away.
• How much gasoline, kerosene, diesel, paraffin, or other extractant can one get from a single barrel of oil?
• "' Perstraction "'is a typical perstraction includes two liquid phases but only other phase includes an extractant.
• Diluent is also used as a term in solvent extraction for an inert solvent in which a metal extraction agent ( extractant ) is dissolved.
• Figure 1 to the right explains the basic principle, in which the organic extractant E is contained inside the pores of a porous particle.
• The extractant is able to diffuse to the edge faster than it can be carried away by the solvent, and the concentration profile is flat.
• While during conventional liquid-liquid extraction the solvent and the extractant have to be dispersed, in a SIR setup the affinity resins can be avoided.
• However, there are possible drawbacks of SIR technology, such as leaching of the extractant or clogging of a fixed bed by attrition of the particles.
• The downcomer was used to contact the electrolyte with air and the droplets of the organic extractant attached themselves to the air bubbles created in the downcomer.
• The solute S, which is initially dissolved in the aqueous phase surrounding the SIR particle, physically dissolves in the organic extractant phase during the extraction process.
• Some laboratories analyze for all 13 mineral nutrients and a dozen non-essential, potentially toxic minerals utilizing the " universal soil extractant " ( ammonium bicarbonate DTPA ).
• This implies selecting a suitable extractant with low water solubility, which is sufficiently retained inside the pores, and selecting mechanically stable particles as a solid support for the extractant.
