Liquid-Liquid Extraction-Chromogenic Systems Containing Iron(III), 4-Nitrocatechol and Tetrazolium Salts

Liquid-Liquid Extraction-Chromogenic Systems Containing Iron(III), 4-Nitrocatechol and Tetrazolium Salts

Complex formation and liquid-liquid extraction were studied in systems containing iron(III), 4-nitrocatechol (4NC),tetrazolium salt (TZS), water and organic solvent. Three different TZS were used: 3-(4,5-dimethyl-2-thiazol)-2,5-diphenyl-2H-tetrazolium bromide (MTT), 3-(2-naphtyl)-2,5diphenyl-2H-tetrazolium chloride (Tetrazolium violet, TV) and 2-(4-iodophenyl)-3-(4-nitrophenyl)5-phenyl-2H-tetra...

Spectrophotometric Determination of Cobalt(ii) in a Liquid-liquid Extraction System Containing 4-(2-thiazolylazo) Resorcinol and 2,3,5-triphenyl-2h-tetrazolium Chloride

The complex formation and a liquid-liquid extraction in the cobalt(II) 4-(2thiazolylazo)resorcinol (TAR) 2,3,5-triphenyl-2H-tetrazolium chloride (TTC) water chloroform system was studied. The optimum extractionspectrophotometric conditions were found. The molar ratio of the reacting species was determined to be 1:2:1 (Co:TAR:TTC). The following equilibrium processes were quantitatively examined...

Experimental Investigation of Phase Inversion of Liquid-Liquid Systems in a Spray Extraction Column

An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. The effects of physical properties, mass transfer and column geometry...

Room-temperature silver-containing liquid metal salts with nitrate anions.

The synthesis, structural, thermal and electrochemical properties of fluorine-free silver-containing ionic liquids are presented. The ionic liquid cations are formed by a silver(i) ion surrounded by two 1-alkylimidazole ligands, with the counter anions being nitrate ions. Depending on the alkyl chain length, the complexes were found to be liquids at room temperature or melting slightly above th...
