Crystal structures of deuterated sodium molybdate dihydrate and sodium tungstate dihydrate from time-of-flight neutron powder diffraction
Time-of-flight neutron powder diffraction data have been measured from ∼90 mol% deuterated isotopologues of Na2MoO4·2H2O and Na2WO4·2H2O at 295 K to a resolution of sin (θ)/λ = 0.77 Å(-1). The use of neutrons has allowed refinement of structural parameters with a precision that varies by a factor of two from the heaviest to the lightest atoms; this contrasts with the X-ray based refinements whe...
متن کاملSimple and rapid determination of hydrogen peroxide using phosphine-based fluorescent reagents with sodium tungstate dihydrate.
A simple batch method for the fluorometric determination of hydrogen peroxide using phosphine-based fluorescent reagents has been developed. A rapid, mild and selective derivatization reaction was achieved by adding sodium tungstate dihydrate to the reaction mixture of hydrogen peroxide and a phosphine-based fluorescent reagent. When 4-diphenylphosphino-7-methylthio-2,1,3-benzoxadiazole was use...
متن کاملRealization of Synergism in Sodium Tungstate-Zn
The aim of this present work is to study, the corrosion behavior of carbon steel in well water in the presence of sodium tungstate (ST)-Zn 2+ -N-(phosphenomethyl) iminodiaceticacid (NPMIDA) solutions. Electrochemical studies and FTIR spectral studies and weight loss study have been employed. It was found that the inhibition efficiency (IE) of ST (50 ppm)-Zn 2+ (10 ppm) was improved from 8% to 8...
متن کاملSodium piperidine-1-carbodithioate dihydrate
The asymmetric unit of the title compound, Na(+)·C(6)H(10)NS(2) (-)·2H(2)O, is composed of a sodium cation, a piperidine-dithio-carbamate anion which exhibits positional disorder, and two lattice water mol-ecules. The atoms of the piperidine ring are divided over two sites with occupancy factors of 0.554 (6) and 0.446 (6). In the crystal, the sodium cation (coordination number of 6) and the pip...
متن کاملInteraction of rat liver glucocorticoid receptor with sodium tungstate.
Effects of sodium tungstate on various properties of rat liver glucocorticoid receptor were examined at pH7 and pH 8. At pH 7, [3H]triamcinolone acetonide binding in rat liver cytosol preparations was completely blocked in the presence of 10--20 mM-sodium tungstate at 4 degrees C, whereas at 37 degrees C a 30 min incubation of cytosol receptor preparation with 1 mM-sodium tungstate reduced the ...
