Summary

A normal-phase-HPLC method for determining individual xanthates in mixtures is presented. The quantitative analyses have been carried out after separation on a LiChrosorb-Diol column using the non-polar solvent n-hexane as mobile phase and UV-detection at 254 nm. The developed HPLC procedure possesses a high sensitivity and high speed of analysis, especially for xanthates with longer alkyl chains. This method was applied to the determination of xanthates in technical flotation liquors. Relative standard deviations for contents of 0.6×10−5 mol/l to 1.2×10−5 mol/l were 2.76 to 5.45%. The absolute limit of determination for potassium octyl xanthate is 0.2 ng.
