Zero-Order and First-Derivative Spectrophotometric Determination of Trace Aaounts of Ruthenium After Extraction of Its Ion Association Coaplex by 2,4,6-Tris(2'-Pyridyl)-1,3,5-Triazine and Picrate. (1992)A solvent extraction-spectrophotometric determination of trace amounts of ruthenium has been developed, based on the formation of an ion association complex of ruthenium (III) with 2,4,6-tris(2'-pyridyl)-1,3,5-triazine as ...
Zn(II) and Cu(II) Uptake from Acid Solutions with Microcapsules Containing a Non-Specific Alkyl Phosphonic Extractant (SOCIEDAD CHILENA DE QUIMICA, 2005-12)It is studied the uptake of Zn(II) and Cu(II) from acid aqueous solutions using microcapsules containing 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester, a non-specific extractant, as an alternative method for metals ...
