2, 4-Dimethyl-6-hydroxyacetophenone oxime and 3, 5-dibromo-2, 4-dimethyl-6- hydroxyacetophenone oxime as reagents and diethylamine as a synergist in the extraction and separation of metals

Abstract

2,4-Dimethyl-6-hydroxyacetophenone oxime and 3,5- dibromo-2,4-dimethyl-6-hydroxyacetophenone oxime act as very good reagents for the extraction and separation of Cu(II), Ni(II), Co(II), Fe(III) and Mn(II). Addition of diethylamine as a synergist in the extraction system, not only increases the per cent extraction of the metals but also the molar absorbances of the complexes. The separation of the metals from one another, viz., Cu(II) from Ni(II), Cu(II) from Co(II) and Cu(II) and Ni(II) from Cr(III) becomes far more easier in the presence of diethylamine.
