Non-aqueous Titration of Gatifloxacin in Pharmaceutical Formulations using Perchloric Acid
(2003-10-01)
An inexpensive, simple, precise and rapid method for the determination of fluoroquinolone gatifloxacin in tablets is described. The procedure is based on the use of volumetric dosage in a non-aqueous medium in glacial ...
Inhibiting effect of citric acid on the pitting corrosion of tin
(Kluwer Academic Publ, 1999-01-01)
Potentiostatic and potentiodynamic studies were carried out to establish the inhibiting effects of citric acid on the pitting corrosion of tin. The critical potential (E-crit), which leads to pitting or general corrosion, ...
Radiometric and spectrophotometric studies of the behavior of chromium(VI) oxide in concentrated perchloric acid
(R Oldenbourg VerlagMunchenAlemanha, 1997)
HYDROGEN-BONDING IN THE CRYSTAL-STRUCTURES OF THE ADDUCTS BETWEEN 1-PHENYL-3,5-DIMETHYLPYRAZOLE WITH OXALIC AND PERCHLORIC ACIDS

Protective film growth on tin in perchlorate and citric acid electrolytes
(Elsevier B.V., 2001-03-01)
Voltammetry has been employed to study the influence of systematic additions of citric acid on the E-I curves of Tin in 0.5 M NaClO4, in order to verify the film growth in the presence of the organic acid and the inhibition ...
Development and validation of a nonaqueous titration with perchloric acid to determine sparfloxacin in tablets
(Elsevier B.V., 2001-09-01)
A simple, rapid and inexpensive method for the determination of sparfloxacin in tablets is described. The procedure is based on the use of volumetric dosage in a nonaqueous medium in glacial acetic acid with 0.1 M perchloric ...
Sodium Alginate-Based Ionic Conducting Membranes
(TAYLOR & FRANCIS LTDABINGDON, 2012)
The present study investigates gel polymer electrolytes (GPEs) based on sodium alginate plasticized with glycerol containing either CH3COOH or LiClO4. The membranes showed ionic conductivity results of 3.1 x 10(-4) S/cm ...
Redox and complexation chemistry of the Cr-VI/Cr-V-D-galacturonic acid system
(ROYAL SOC CHEMISTRY, 2004)
The oxidation of D-galacturonic acid by Cr-VI yields the aldaric acid and Cr-III as final products when a 30-times or higher excess of the uronic acid over Cr-VI is used. The redox reaction involves the formation of ...
Miscibility, crystallinity and morphological behavior of binary blends of poly(ethylene oxide) and poly(methyl vinyl ether-maleic acid)
