Abstract: Three HPLC methods for the separation and determination of xanthate mixtures are described. The chromatographic behaviours, advantages and application ranges of variousmethods have been discussed in detail. A calculation method for determining the results of individual xanthates from the complicated chromatographic peaks of xanthate mixtures is presented.The limits of detection are 0.15-2.0ng.
Key words: xanthate, dixanthogen, collector, liquid chromatography
