This includes dissolving the flotation concentrate in sulphuric acid, followed by solvent extraction using a suitable extractant
such as TEHPA, Alamine336, TBP or Cyanex 923.
EDTA, contained in the Mehlich-III solution (Mehlich 1984), is an effective extractant
for microelement-humic substance complexes, which outperforms other extractants
for SOM fractions (Gerzabek et al.
Sales of MTBE for application in reformulated gasoline will remain considerably larger than those in solvent and extractant
The desired species so extracted were found to have a stoichiometric composition as UO2(NO3)2.DOHA and UO2(NO3)2.2DOHA at lower and higher concentration of extractant
Reduction of relationship through the increase of the quantity of extractant
may allow a better effectiveness in the neutralization of acids present in the soil (SILVA et al., 2008).
(13.) Eloff JN, Which extractant
should be used for the screening and isolation of antimicrobial components from plants?
Significant correlations have been found between the extractant
except for Bray whi ch showed non - significant correlation.
An effective extractant
with high selectivity for metal ions is in high demand for analytical applications, recycling of resources, and waste treatment purposes.
In recent years, there are many researches about ionic liquid as an extractant
for dye from various samples such as Congo red, Sudan dye, methyl orange, and so on [2-4], but the application of ionic liquids is restrained due to its high cost and hard to recycle [5, 6].
In this paper, 2-ethyl-1,3-hexanediol was chosen as the extractant
to extract boron from underground brine.
Specifically, the ratio at which Nd and Dy move to the extractant
change as the pH level of the acid increases.
