Absorption of chlorine into aqueous bicarbonate solutions and aqueous hydroxide solutions

AIChE Journal, 1996
AbstractThe absorption of Cl2 into aqueous bicarbonate and aqueous hydroxide solutions was studied both experimentally and theoretically. The rate coefficient of the reaction between Cl2 and OH− was estimated over the temperature range of 293–312 K and fitted by the Arrhenius equation: .If Cl2 were assumed to react only with water and OH− in an ...

Ozonation of Aqueous Solutions of Nitrobenzene

Ozone: Science & Engineering, 1984
Abstract The ozonation of nitrobenzene in aqueous solution is investigated by determining COD removal, ozone consumption and product distribution at different degrees of ozonation.Results reveal that complete nitro benzene elimination is achieved at relatively short ozonation times, with no appreciable accumulation of unsaturated intermediates.Oxida ...

PHOTODEGRADATION OF HYDROXYCHLOROTHALONIL IN AQUEOUS SOLUTIONS

Environmental Toxicology and Chemistry, 2001
Abstract Hydroxychlorothalonil is the principal degradation product of the fungicide chlorothalonil in soil, and it is routinely detected in leachate from golf course greens at concentrations as high as 2 ppm. However, it is not detected in receiving waters of shallow ponds.

Radiochemistry of Aqueous Solutions [PDF]

Nature, 1944
IN a recent review of radiochemical reactions, that is, reactions induced by α-particles and particularly by X-rays, Allsopp1 affirms the conclusion that in gaseous systems there is a great similarity between radiochemical and ordinary photochemical processes, and that their mechanisms are essentially the same.

The Entropy of Aqueous Solutes

The Journal of Chemical Physics, 1951
The standard partial molal entropies of monatomic ions and of non-electrolytes in aqueous solution can be represented by the empirical expressions, for monatomic ions:S̄0=(3/2)R lnM+37–270Z/re2,for non−electrolytes:S̄0=Sint+(3/2)R lnM+10–0.22VM.Here Z is the absolute value of the charge on the ion, re is the effective radius of the ion, and VM is the ...

Aqueous solutions of polyvinylpyrrolidone [PDF]

Die Makromolekulare Chemie, 1968
AbstractThe properties of polyvinylpyrrolidone, in water and salt solutions, are examined by measuring the heat capacities, specific volumes and reduced viscosities. The heats of solution in water are of the order of −4 kcal per mole of monomer unit, they are decreased in the presence of salts. The results are discussed in terms of the mechanism of the

Structure of Pyruvate in Aqueous Solution

Nature, 1958
IN a recent publication and its addendum by Dickens and Williamson and by Bellamy and Williams1, it was reported that the infra-red spectra of lithium pyruvate and hydroxypyruvate in the solid state show no ketonic carbonyl peak, and it was suggested that these compounds exist as the hydrate, RCH2C(OH)2COO−Li+, in the solid and in aqueous solution and ...

Photochemistry of norharmane in aqueous solution

Photochemical & Photobiological Sciences, 2009
The photochemistry of norharmane (9H-pyrido[3,4-b]indole) in acidic (pH 5.0+/-0.1) and alkaline (pH 10.0+/-0.1) aqueous solutions was studied. The photochemical reactions were monitored by TLC, UV/VIS absorption spectroscopy, high-performance liquid chromatography (HPLC), electronic ionization-mass spectrometry (EI-MS), UV-laser desorption/ionization ...
