dye cations and solvent extraction methods.
The original intention of this project was to study
selected onium extractions in continuation of previous work
carried out in this laboratory.
The extraction of Cr(VI) with onium salts into organic
solvents had been studied by previous workers who had shown
that Cr(VI) could just as readily be extracted from acid
solution without the addition of an onium salt. A study has
been made of the effect of various onium compounds, and different
organic solvents on this extraction. The effect of pH, as well
as interfering ions was studied. In the present study, in
spite of the colour stability of the complex and the coefficient
of variation being 0.4%, a low apparent molar absorptivity was
obtained. [Continues.]
