TL;DR: In this article, the results of the extraction of fourteen different quaternary cations with nineteen different anions into four different solvents were discussed in terms of the effects of the cation, the anion and the organic solvent on the distribution ratio.

TL;DR: In this article, the surfactant is extracted into 1,2-dichlorobenzene as a neutral adduct with potassium tetrathiocyanatozincate(II), and zinc(II) in the extract is determined spectrophotometrically after addition of l-(2-pyridylazo)-2-naphthol and triethanolamine.

TL;DR: The results of the extraction of quaternary phosphonium and arsonium salts from aqueous solution into the organic solvents, chloroform, dichloromethane, 1,2-dichloroethane and 2,2'-Dichlorodiethylether over a range of cation and anion concentrations are reported in this paper.

TL;DR: In this paper, Triphenylmethylarsonium thiocyanate (THI) was used for colorimetric micro-estimation of cobalt with an accuracy of about 2%.

TL;DR: The colorimetric determination of palladium is described in this article, which involves the extraction of chloro(PAP)palladium(II) from an acidic aqueous solution into o-dichlorobenzene and measurement of the absorbance of the extract solution.
