The effect of experimental conditions on the formation of Dixanthogen by triiodide oxidation in the determination of ethyl xanthate by HPLC-ICP-MS/MS
Anal Sci 2022 Sep;38(9):1221-1231.PMID:35796995DOI:10.1007/s44211-022-00155-x.
The rising concern over the environmental impact of xanthates, especially in the arctic region, has increased the need to study these traditional flotation reagents in greater detail. The environmental concern relates mostly to the formation of carbon disulfide (CS2) and the heavy metal complexes of xanthates. Due to the unstable nature and multiple reaction mechanisms of xanthates, their reliable determination at low concentration levels is difficult. In this study, a xanthate pretreatment method was optimized and applied for the determination of ethyl xanthate (EX-) by high performance liquid chromatography-inductively coupled plasma tandem mass spectrometry (HPLC-ICP-MS/MS). Ethyl xanthate was oxidized to diethyl Dixanthogen ((EX)2) by triiodide (I3-) in aqueous solution and the formed (EX)2 was extracted into n-hexane. Important experimental parameters, including pH, I3- amount, and oxidation time, were optimized and the detection limit of 0.29 mg L-1 for potassium ethyl xanthate was obtained. During the optimization experiments, it was found that the oxidation reaction resulted in multiple products, decreasing the efficiency of (EX)2 formation and, therefore, the sensitivity of the method. The proposed method was applied to wastewater samples with recoveries of 105-106%. This study provides a selective method for the determination of ethyl xanthate and introduces novel information on the parameters affecting the oxidation of xanthates.
Reduction and determination of dixanthogens
Talanta 1971 Jun;18(6):649-52.PMID:18960926DOI:10.1016/0039-9140(71)80099-1.
A convenient method for the reduction and determination of dixaathogen has been developed. It is based on the quantitative reaction of Dixanthogen with zinc amalgam to form xanthate; the latter can be determined by iodine titration, potentiometric titration with silver nitrate or by spectrophotometry at 310 mmu. Dixanthogen can be determined in mixtures containing xanthate, by titration of aliquots with and without reduction. Higher dixanthogens can also be determined, and flotation liquors analysed.
Determination of small quantities of xanthate
Talanta 1969 Aug;16(8):1129-35.PMID:18960617DOI:10.1016/0039-9140(69)80157-8.
A new spectrophotometric method for the determination of very small amounts of xanthate in solutions, particularly cyanide solutions from gold-extraction plants, is described. It is based on the formation and extraction of copper(II) xanthate. The coefficient of variation is 1.0% at the 40-ppm level and 3.4% at the 4-ppm level and the lower limit of determination is approximately 0.5 ppm. Copper(II) xanthate normally decomposes into copper(I) xanthate and Dixanthogen, but in the proposed method the decomposition is delayed.
Molecular modeling study on the relative stabilities of the flotation products for arsenic-containing minerals: dixanthogens and arsenic(III) xanthates
J Colloid Interface Sci 2005 Apr 15;284(2):694-7.PMID:15780312DOI:10.1016/j.jcis.2004.10.046.
The interactions of As(III) ion with C(2)H(5)OCS(-)(2) and C(2)H(5)SCS(-)(2), known as the most popular collector ions, were studied by density functional theory (DFT) at the B3LYP/6-31G** level in connection with the arsenic-containing minerals realgar, orpiment, and arsenopyrite. The Dixanthogen formations of these ions were also investigated at the same level of theory. The central purpose of this paper is to compare the stabilities of the major flotation products, namely As(III) xanthates and dixanthogens. The results show that the magnitudes of the interaction energies for the formations of As(III) xanthates and dixanthogens increase when the oxygen atom is replaced by the sulfur atom in C(2)H(5)OCS(-)(2). Therefore, the C(2)H(5)OCS(-)(2) ion is preferred in these formations. The results obtained are in agreement with the experimental data reported.
Determination of trace amounts of the flotation collectors ethyl xanthate and diethyl dithiophosphate in aqueous solutions by cathodic stripping voltammetry
Talanta 1986 Oct;33(10):801-6.PMID:18964204DOI:10.1016/0039-9140(86)80197-7.
A cathodic stripping method has been devised for determination of low concentrations of the flotation collectors ethyl xanthate, diethyl Dixanthogen and diethyl dithiophosphate. The limit of detection for ethyl xanthate was 1 x 10(-8)M by the differential pulse technique and with deposition for 2 min at -0.1 V. Three peaks were observed, each increasing in different concentration ranges of ethyl xanthate. A reaction mechanism is proposed. The detection limit for diethyl dithiophosphate was 1 x 10(-7)M by the differential pulse technique and with deposition for 3 min at -0.1 V. The analytical method was applied to determine ethyl xanthate in a sulphide mineral flotation plant and the amount of adsorbed ethyl xanthate and diethyl dithiophosphate on Cu(2)S. It was found that the adsorbed ethyl xanthate forms nearly a monolayer on Cu(2)S and that the amount of adsorbed diethyl dithiophosphate corresponds approximately to 0.4 monolayer.
