Ionizing Radiation-Induced Destruction of Benzene and Dienes in Aqueous Media

March 28, 2006
Author(s)
M I. Al-Sheikhly, Dianne L. Poster, Jung-Chul An, Pedatsur Neta, Joseph Silverman, Robert E. Huie
Pulse radiolysis with spectrophotometric and conductometric detection was utilized to study the formation and reactions of radicals from benzene and dienes in aqueous solutions. The benzene OH adduct, C6H6OH, reacts with O2 (k = 3 x 108 L mol-1 s-1) in a

Radiolytic Reactions of Monochloramine in Aqueous Solutions

September 1, 2003
Author(s)
G A. Poskrebyshev, Robert E. Huie, Pedatsur Neta
Monochloramine reacts with hydrated electrons very rapidly, k(NH 2 CI + e aq -) = (2.2 0.2) x 10 10 L mol -1 , to produce oNH 2 radicals. It reacts with oOH radicals more slowly, k(NH 2 Cl + oOH) = (5.2 0.6) x 10 8 L mol -1 s -1 , to produce oNHCl radicals

Measurements of the Infrared Absorption Cross-Sections of Haloalkanes and Their Use in a Simplified Calculational Approach for Estimating Direct Global Warming Potentials

May 1, 2003
Author(s)
Vladimir L. Orkin, A G. Guschin, I K. Larin, Robert E. Huie, Michael J. Kurylo III
The infrared absorption cross-sections and integrated band intensities for 21 haloakanes: CFCl 3 , CF 2 Cl 2 , CF 2 Br 2 , CH 2 F 2 , CHR 2 Cl, CHF 2 Br, CF 3 Br, CHCl 2 -CF 2 Cl, CHFCl-CFCl 2 , CHCl 2 -CF 3 , CHClBr-Cf 3, CHFCl-CF d2^Cl, CHFBr-CF 3 , CHF

NDRL/NIST Solution Kinetics Database on the WEB

March 1, 2003
Author(s)
Robert E. Huie
A Solution Kinetics Database, jointly created byNIST and the Notre Dame Radiation Laboratory, hasbeen made available on the Internet in a format similarto that utilized by the popular NIST KineticsDatabase, which covers gas-phase reactions. TheSolution

OH Reactivity and UV Spectra of Propane, n-Propyl Bromide, and Isopropyl Bromide

March 1, 2003
Author(s)
S N. Kozlov, Vladimir L. Orkin, Robert E. Huie, Michael J. Kurylo III
The rate constants for the reactions of OH radicals with the 1-bromopropane, 2-bromopropane, and propane were measured using the flash photolysis reasonance fluorescence technique over the temperature range between 210 K and 480 K. Arrhenius plots exhibit

Radiolytic Dechlorination of Polychlorinated Biphenyls in Transformer Oil and in Marine Sediment

November 1, 2002
Author(s)
M Chaychian, C A. Jones, Dianne L. Poster, Joseph Silverman, Pedatsur Neta, Robert E. Huie, M I. Al-Sheikhly
Radiolytic dechlorination of PCBs in transformer oil and in marine sediments has been studied. At low PCB concentrations, complete degradation of the PCBs in transformer oil was achieved without degradation of the oil. Addition of an organic base

Temperature Dependence of the Acid Dissociation Constant of the Hydroxyl Radical

November 1, 2002
Author(s)
G A. Poskrebyshev, Pedatsur Neta, Robert E. Huie
The acid dissociation constant of the hydroxyl radical in aqueous solution was determined by pulse radiolysis from the pH dependence of the rate constant for reaction of the OH/O - radical with benzoate ions. The rate constant and the pKa( OH) values were
