“…121 The separation of the 0-butyl derivatives of selenium, tellurium, arsenic, antimony and bismuth was achieved on a c 1 8 column with acetonitrile as mobile phase. The 0-ethyl derivatives were separated on a Nucleosil CN column with n-hexane/t-butyl methyl ether as the mobile phase.…”

Selenium appears in the natural selenium cycle in the form of several organic and inorganic compounds. The biologically beneficial and detrimental effects of 'selenium' must be ascribed to particular selenium compounds. The identification and quantification of selenium compounds in biological and environmental samples is required for an understanding of the role of selenium. The highperformance liquid-chromatographic (HPLC) methods for the separation, identification and quantification of selenite, selenate, hydrogen selenide, methaneselenol, bis(organothi0) selenides, trimethylselenonium salts, selenoamino-acids, selenium derivatives of carbohydrates, selenoproteins, selenonucleosides and other miscellaneous selenium compounds are summarized (193 references) and pertinent detection modes discussed. Advantages and disadvantages of the methods are pointed out. The literature is covered since 1974, the year of the first publication in this field.

“…Extraction with organic solvents was used to dissolve the water-insoluble complexes. In addition, the stability of the complexes may also be improved because it has been found that polar compounds, such as water or methanol can displace xanthate as the complexing ligand [25]. Ethyl acetate and dichloromethane resulted in significantly higher absorbance values than n-hexane and diethyl ether.…”

The present study provides a novel, selective analysis method for the determination of low xanthate concentrations. The rising concern over the environmental effects of xanthates demands the development of analysis methods which this study answers. Complex formation in aqueous solution between xanthates and an excess of Co(II), Ni(II), Pb(II), Cd(II), Cu(II), and Zn(II) ions was utilized to selectively determine xanthates by high-performance liquid chromatographyinductively coupled plasma tandem mass spectrometry for the first time. The complexes that were formed were extracted to ethyl acetate using liquid-liquid extraction and separated by high-performance liquid chromatography technique before the quantitative determination of metal ions and sulfur in the xanthate complexes. Good separation and high measurement sensitivity were achieved using Cu(II) as the complex metal ion. The analysis method was optimized for the determination of sodium isopropyl xanthate and sodium isobutyl xanthate with detection limits of 24.7 and 13.3 μg/L, respectively. With a linear calibration range of 0.1-15 mg/L and a total analysis time of 4-5 min, the present method is a fast and sensitive option for selective xanthate determination.

“…The selenium and other metal xanthates were extracted immediately into hexane, because the xanthates are decomposed by polar substances such as water, methanol, triethylamine and pyridine. 121 The separation of the 0-butyl derivatives of selenium, tellurium, arsenic, antimony and bismuth was achieved on a c 1 8 column with acetonitrile as mobile phase. The 0-ethyl derivatives were separated on a Nucleosil CN column with n-hexane/t-butyl methyl ether as the mobile phase.…”
