Gas chromatography of davalent transition metal chelates
Journal ArticleDOI
Volatile alkaline earth chelates of fluorinated alkanoylpivalylmethanes: A thermogravimetric, gas chromatographic and mass spectral study
TL;DR: In this article, the synthesis details and characterisation of some alkaline earth chelates of fluorinated alkanoylpivalylmethanes are given, and the mass spectra of the calcium, strontium and barium compounds exhibit peaks due to polymeric ions.
Journal ArticleDOI
A new reagent for the detection and determination of small amounts of the sulphate Ion
TL;DR: In this paper, an aqueous solution of 2-aminoperimidine hydrochloride is proposed as a new reagent for the detection and determination of the sulphate ion.
Journal ArticleDOI
Volatile complex chelates of rare earth and alkali metals
TL;DR: In this article, rare earth chelates of the type ML 3 have been shown to react with alkali metal ions and an additional ligand to form complex Chelates (mixture of rare earth metal and fluorinated acetylacetone), and the differences in the u.v. and i.r.
Journal ArticleDOI
Some derivatives of rhodanine as analytical reagents
TL;DR: In this article, two derivatives of rhodanine were investigated as potential spectrophotometric and spot test reagents, and sensitivity reactions for silver, gold, copper, copper(I), mercury(II), palladium and some other metals were described.
