Selective Speciation of Ferric Iron by a New Heterocyclic Ligand
The synthesis and analytical applications of the new heterocyclic ligand are described. The complexation reaction of the ligand with some cations was studied in aqueous methanol at room temperature using the spectrophotometric method. Results revealed that only the absorption spectra of the Fe (III)–ligand complex show a high redshift of the absorption maximum in the aqueous methanol soluti...
متن کاملInhibition of methanogenesis by human bile.
The factors that regulate methanogenesis in humans have not been established. The presence of bile acid, which is lost into the colon from the small intestine, may be an important regulatory factor of methanogenesis. To examine this possibility, the effect of human bile on methane production by faecal cultures, and the in vivo effect of biliary diversion on breath methane excretion in a methano...
متن کاملInhibition of rumen methanogenesis by methane analogues.
Extremely low concentrations of chloroform and carbon tetrachloride and somewhat larger concentrations of methylene chloride inhibited the formation of methane by the rumen microbiota in the presence or absence of added substrate. The accumulation of hydrogen at these low concentrations indicates a selective inhibition of methanogenesis. Presumably, these inhibitors affect one or more of the re...
متن کاملThe binding of ferric iron by ferritin.
Equilibrium-dialysis experiments with 59Fe-labelled Fe(III) chelate solutions show that ferritin is capable of binding a limited number of Fe(III) atoms. Some of this Fe(III) is readily removed, but up to about 200 Fe(III) atoms/molecule remain bound after extensive washing. Some exchange of labelled Fe(III) with endogenous unlabelled ferritin Fe occurs during prolonged dialysis against 59Fe(II...
متن کاملSynergistic Competitive Inhibition of Ferrous Iron Oxidation by Thiobacillus ferrooxidans by Increasing Concentrations of Ferric Iron and Cells.
Oxidation of ferrous iron by Thiobacillus ferrooxidans SM-4 was inhibited competitively by increasing concentrations of ferric iron or cells. A kinetic analysis showed that binding of one inhibitor did not exclude binding of the other and led to synergistic inhibition by the two inhibitors. Binding of one inhibitor, however, was affected by the other inhibitor, and the apparent inhibition const...
