Gravimetric determination of nickel as the ternary Nickel - pyridine - picrate complex
(1982)
A study of ternary complex formation between nickel, pyridine and picrate ion has been made. The metal - pyridine complex reacts with picrate to give an insoluble, stable, green precipitate. Conditions of formation, ...
Extraction-spectrophotometric determination of iron as the ternary tris(1,10-phenanthroline)-iron(II)-picrate complex
(1985)
A highly sensitive extraction-spectrophotometric method has been developed for the determination of iron based on the formation of a ternary complex with 1,10-phenanthroline as a primary ligand and picrate as a counter ...
Zero-Order and First-Derivative Spectrophotometric Determination of Trace Aaounts of Ruthenium After Extraction of Its Ion Association Coaplex by 2,4,6-Tris(2'-Pyridyl)-1,3,5-Triazine and Picrate.
(1992)
A solvent extraction-spectrophotometric determination of trace amounts of ruthenium has been developed, based on the formation of an ion association complex of ruthenium (III) with 2,4,6-tris(2'-pyridyl)-1,3,5-triazine as ...
Synthesis and Characterization of the Europium(III) Pentakis(picrate) Complexes with Imidazolium Countercations: Structural and Photoluminescence Study
(AMER CHEMICAL SOCWASHINGTON, 2012)
Six new lanthanide complexes of stoichiometric formula (C)(2)[Ln(Pic)(5)]-where (C) is a imidazolium cation coming from the ionic liquids 1-butyl-3-methylimidazolium picrate (BMIm-Pic), 1-butyl-3-ethylimidazolium picrate ...
Spectrophotometric and derivative spectrophotometric determination of iron by extraction of the iron(II)-TPYZ-picrate ion-association complex
(1989)
A solvent extraction-spectrophotometric determination of microamounts of iron has been developed, based on the formation of an ion-association complex of iron(II) with 2,4,6-tris(2′-pyridyl)-1,3,5-triazine as primary ligand ...
IMPROVED SYNTHESIS OF ETA-6-ARENE-ETA-6-CYCLOPENTADIENYL-IRON (II) SALTS - SYNTHESIS OF ETA-6-HYDRAZINOBENZENE-ETA-6-CYCLOPENTADIENYL-IRON (II) PICRATE
(Acad Brasileira De CienciasRio De JaneiroBrasil, 1982)
