Spectroscopic evidence for selenium(IV) dimerization in aqueous solution.

The aqueous speciation of selenium(iv) was elucidated by a combined approach applying quantum chemical calculations, infrared (IR), Raman, and (77)Se NMR spectroscopy. The dimerization of hydrogen selenite (HSeO3(-)) was confirmed at concentrations above 10 mmol L(-1) by both IR and NMR spectroscopy. Quantum chemical calculations provided the assignment of vibrational bands observed to specific...

Kinetics of Polymerisation of Furfuryl Alcohol in Aqueous Solution

Kinetic information on the polymerisation of furfuryl alcohol catalysed by Clark-Lubs' aqueous buffer in the pH range of 1.G2.2 has been derived from the rate of increase ofcolour intensity measured with a photoelectric colorimeter. The polymerisation reaction is found to be of zero order, with the activation energy increasing exponentially with pH. The time required to reach the extent of reac...

Racemization kinetics of meluadrine tartrate in aqueous solution.

The kinetics of racemization of meluadrine tartrate in aqueous solution was investigated by HPLC, over the pH range of 1.2 to 12 at 40, 60 and 80 degrees C. The racemization was followed by measuring both the residual (R)-enantiomer and formed (S)-enantiomer of meluadrine. The pH-racemization rate profile of meluadrine showed a minimum racemization rate constant between pH 4 and 6, and the rate...

Degradation Kinetics of Benzyl Nicotinate in Aqueous Solution

The degradation of benzyl nicotinate in aqueous solution over a pH range of 2.0-10.0 at 50+/-0.2 degrees was studied. The degradation was determined by high performance liquid chromatography. The degradation was observed to follow apparent first-order rate kinetics and the rate constant for the decomposition at 25 degrees was estimated by extrapolation. The reaction was shown to be hydroxide io...

Kinetics of Chromium Sorption on Biomass Fungi from Aqueous Solution

The kinetics of chromium ions sorption from aqueous solution on fungi biomass have been investigated in a batch system. The experimental data were analysed based on an intraparticle diffusion equation and a pseudo-second-order mechanism, in order to predict the constant rate of sorption and the equilibrium capacity with the effect of initial chromium ions concentration, temperature and initial ...
