An accurate and rapid radiochemical method has been developed for the determination of microgram amount of silver employing potassium ethyl xanthate as a substoichiometric radiochemical reagent. The light yellow coloured silver ethyl xanthate formed was extracted into nitrobenzene from sulphuric acid media. The effect of foreign ions on the extraction was studied. The method was applied to the ...

Digenite fine particles are easily oxidized and ferric ions (Fe3+) commonly exist in the flotation pulp of digenite. This study investigated effect Fe3+ on sulfidization digenite using sodium butyl xanthate (SBX) as a collector. The results microflotation experiments show that rate recovery can be improved by adding Na2S SBX, whereas existence large amounts is not beneficial for adsorption, zet...

A series of triorganophosphinegold(1) dithiocarbamate (R(3)PAuS(2)CNR'(2)) and xanthate (R(3)PAuS(2)COR') complexes have been prepared and characterised spectroscopically. Based on crystallographic evidence, the molecules feature linear gold(1) geometries defined by sulphur and phosphorus donors. The complexes, along with a series of known anti-cancer agents, have been screened against a panel ...

Atomic force microscopy (AFM) has been applied to study the adsorption morphology of various collectors, i.e., potassium ethyl xanthate (KEX) and amyl (PAX) Cytec Aerofloat 238 (sodium dibutyl dithiophosphate), on chalcocite in situ aqueous solutions. The AFM images show that all these collectors adsorb strongly chalcocite. Xanthate adsorbs mainly form insoluble cuprous (CuX), which binds with ...

Tricyclodecan-9-yl-xanthogenate (D609) has been extensively studied in biological systems and exhibits a variety of biological functions, including antiviral, antitumor, and anti-inflammatory activities. Most of these activities have been largely attributed to the inhibitory effect of D609 on phosphatidylcholine-specific phospholipase C. However, as a xanthate derivative, D609 is a strong elect...

A new copper-catalyzed in situ generation of aryl thiolates strategy was successfully developed for the one-pot synthesis of substituted benzothiazoles from 2-iodoanilides using xanthate as a thiol precursor. A wide range of 2-iodoanilides with both electron-releasing and electron-withdrawing groups produced the corresponding benzothiazoles in good yields. Further, this one-pot protocol was suc...

In this work, molecular tuning of metal xanthate precursors is shown to have a marked effect on the heterojunction morphology of hybrid poly(3-hexylthiophene-2,5-diyl) (P3HT)/CdS blends and, as a result, the photochemical processes and overall performance of in situ fabricated hybrid solar cells. A series of cadmium xanthate complexes is synthesized for use as in situ precursors to cadmium sulf...

The copper ion is a common metal in the pulp beneficiation industry, and it affects recovery of target minerals. In this study, we investigated interaction mechanism ions with surface sulfidized malachite its effect on flotation. flotation behavior hydrophobicity were studied by microflotation contact-angle tests. experimental results showed that modified suitable concentration was enhanced inc...
