New methods for the determination of elements in trace amounts
ZusammenfassungVerfahren werden besprochen, die in den letzten Jahren hauptsächlich in den Laboratorien des Autors entwickelt wurden. Der Überblick umfaßt folgende Kapitel: Reagentien und Reaktionen,
Solubility of iron in carbonic acid solutions
From data in literature a model has been developed for the prediction of the concentration of dissolved iron, resulting from the corrosion of steel in carbonic acid. It explains the occurrence of
Synthesis of Pyridophenanthrolines via a Three-Component Reaction Involving 1,10-Phenanthrolin-5-Amine
A facile and efficient method for the synthesis of benzo[b]pyrido[3,2-f][1,7]phenanthrolines and dipyrido[4,3-b:3′,2′-f][1,7]phenanthrolines has been developed in high yields. Using EtOH as a solvent
Mechanism of iron ions sorption by chitosan-genipin films in acidic media.
TLDR
It was observed that the Ch-Ge films only presented sorption capacity at pH 3.5 in the presence of α-hydroxypolycarboxylic acids, through electrostatic interactions, which allows proposing a broad application of Ch- Ge films to beverages and other liquids containing malic, tartaric or citric acids.
Heterogeneous Association of the Ions of Dyes in Solutions (Review)
General trends in the development of investigations of ion associates, involving an ion of an organic dye, in aqueous solutions are considered. The spectral-luminescent, equilibrium, and
Effect of Temperature, Bicarbonate, and MEG Concentrations on CO2 Corrosion of Carbon Steels
The CO2 corrosion of two mild steels has been studied as function of monoethylene glycol (MEG) and bicarbonate concentration at conditions where FeCO3 precipitation was sparse. The steel coupons we...
Iron(II) phenanthroline-resin hybrid as a visible light-driven heterogeneous catalyst for green oxidative degradation of organic dye
Abstract A novel resin immobilized iron(II) phenanthroline [FePR] is prepared, characterized and exploited to understand C–C/C–O cleavage in Rhodamine B dye under visible light (λ ≥ 420 nm). Studies
Organic Reagents in Photometric Analysis
I. INTRODUCTION One of the most remarkable properties widely used in chemical analysis is the ability of a metal ion solution or a chemical substance to change its color under the effect of external
Properties and structure of two fluorinated 1,10-phenanthrolines
Abstract We report the synthesis, X-ray structure, absorbance and emission of 4,7-bis(4-fluorophenyl)-1,10-phenanthroline and 4,7-bis-(4′-trifluoromethyl-biphenyl-4-yl)-1,10-phenanthroline.
Coordination chemistry of iron triad metals with organic N-donor ligands and boron cluster anions [B10H10]2−, [B12H12]2−, and [B10Cl10]2−: Complexation and accompanying processes
Synthesis and structures of coordination compounds of the iron triad metals with N-donor ligands (Bipy, Phen, and BPA) and boron cluster anions [B10H10]2−, [B12H12]2−, and [B10Cl10]2− are described.

Alkali metal derivatives of pentafluorodimethylheptan-3,5-dione and heptafluorodimethyloctan-4, 6-dione are described. Their mass spectra were examined and the integrated ion-current technique was
Mass spectrometry of metal chelates-I Detection on the picogram scale.
TLDR
A method has been developed for the detection and estimation of metals in the form of chelates in amounts down to 10(-12) g and the integrated ion current is directly proportional to the concentration of metal chelate.
