    Pulse radiolysis of aqueous solution of pentacyanocobaltate(II). Detection and characterization of pentacyanocobaltate(I). Transient spectra observed on the pulse radiolysis of aqueous solutions of nitric oxide at pH have been assigned to the species NO −, N 2 O 2 −, and N 3 O 3 −.In acid solution these species are protonated to form the corresponding acids, HNO, HN 2 O 2, and HN 3 O the basic and acid forms undergo similar reactions, but at different rates, to form the products of radiolysis N 2.

The conditions . @article{osti_, title = {Mechanism of the radiolysis of water}, author = {Bugaenko, L T and Byakov, V M and Kabakchi, S A}, abstractNote = {The authors discuss the modern concepts of the radiolysis of water and a variant of the mechanism of radiolysis that most satisfactorily describes the experimental functions not only in dulute but also in concentrated aqueous solutions.

      Water radiolysis - ionizing radiation induced occurrence of water radicals. Radicals attacking substructures in cells, p.e. DNA. One-electron oxidation of 1,1'-dimethylselenourea (DMSeU) by hydroxyl radicals, one-electron-specific oxidants, was studied using pulse radiolysis technique in aqueous solution. Hydroxyl (rad OH) radicals and one-electron oxidants, N 3 rad, X 2 rad - (X=Cl, Br, and I) react with DMSeU to form a transient having an absorption spectrum with λmax at nm.

Radiolysis is the dissociation of molecules by ionizing is the cleavage of one or several chemical bonds resulting from exposure to high-energy flux.

The radiation in this context is associated with ionizing radiation; radiolysis is therefore distinguished from, for example, photolysis of the Cl 2 molecule into two Cl-radicals, where (ultraviolet or visible spectrum) light is used.

Radiolysis of water has been extensively investigated by pulse radiolysis and other techniques. On application of short electron pulses, solvated electrons, H 2 O + cations, and excited water molecules (H 2 O ∗) result [8,9].Main primary reactions of these species are summarized in Fig.

Water in an excited state can decompose to species such as hydroxyl radicals (HO), hydrogen atoms (H. Paulenova, in Advanced Separation Techniques for Nuclear Fuel Reprocessing and Radioactive Waste Treatment, Radiolysis in aqueous solutions.

Radiolysis in aqueous solutions has an entirely different effect than in solid materials; water molecules become either excited or ionized. The ionization event occurs on the time scale of an electronic transition. Model for radiolysis of water and aqueous solutions of H2, H2O2 and O2 Article (PDF Available) in Radiation Physics and Chemistry 77(8) August.

Using the method of pulse radiolysis in irradiated aqueous solutions of sulfuric acid, a short-lived optical absorption (maximum at mμ due to the HSO4 (or SO 4 −) radical has been detected. The molar extinction coefficient of this product (∼ liter/mole cm) and the velocity constant of the reaction between the OH radical and the HSO 4 − (or SO 4 2−) ion (∼ liter.

The rate constants for the reactions of OH radicals with Np(IV) and Np(V) ions in aqueous perchloric acid solutions are practically independent of the acidity of the medium and are quite high, in order to exclude the recombination of the OH radicals in the presence of these ions.

Pulse radiolysis Abstract Observations of the solvated electron in water and the common aliphatic alcohols have been made in the time region ∼ 20– psec. Molar concentrations of acid have been used to scavenge e aq − and k (e aq − +H aq +) has been measured as ( ± ) × 10 10 liter/molesec for [H aq + ] from to M.

The radiolysis of water due to ionizing radiation results in the production of electrons, H atoms, OH radicals, H3O+ ions and molecules (dihydrogen H2 and hydrogen peroxide H2O2). A brief history of the development of the understanding of water radiolysis is presented, with a focus on the H2 production.

This H2 production is strongly modified at oxide surfaces. To demonstrate the efficacy of the high-temperature pulse radiolysis cell holder, e s − reaction kinetics with Cr 3+ were measured in a 5 mM CrCl 3 solution in LiCl–KCl eutectic (42 mol. % KCl) at 50 °C intervals between °C and °C.

Water3 60Co has thus a LET value of – keV µm−1 whereas the value is keV µm−1 in the case of MeV alpha particles (Po) [8].The LET is one of the important parameters to account for the yields of products obtained in radiolysis.

After the s, the development of nuclear reactors enabled more and more radionuclides to be. Existing methods for chemical dosimetry of pulsed electronic radiation are reviewed. Sources of this type of radiation are described, and the special problems arising in the dosimetry of high dose rates (up to 10 14 rad s −1) are effect of dose rate on the yield of radiolysis products is discussed in detail for a number of systems used in dosimetry (aqueous solutions.

Our purpose here is to bring some of these results together in order to emphasize the power and usefulness of pulse radiolysis experiments both for elucidating enzyme reaction mechanisms, and for gaining information on the structure of proteins in aqueous solutions.

G.The use of a signal sampling and averaging technique has improved the time resolution of the measurements of G(e aq –) following irradiation of aqueous solutions by 3 MeV protons in a pulse of ca. 1 ns. The maximum measured G(e aq –) for pure water and for water containing concentrated scavengers for H + ions and OH radicals was in all cases significantly higher than previously reported.1.
