Sulfate ions deposited on iron oxide were thermally stable up to ca. 770 K. When pyridine, ammonia, n-butane, and 1-butene were preadsorbed, however, they decomposed to generate gaseous SO 2 at much lower temperatures due to the reaction between these molecules and sulfate ions. Implications ...
MS profiling of peak 1 (RT 2.34 min) produced a parent ion peak at [M − H]+ m/z 441.0840 Da and daughter ions 251.0365, 233.0297 and 124.9848 Da, which corresponds to catechin gallate, and its fragmentation pattern revealed it would be catechin 3-O-gallate. MS spectra are provided ...
(positively chargedions) and permanganateanions(negative ions) also are known to act as homogeneous catalysts for hydrogen activation.Palladiumchloride is employed industrially in the catalytic oxidation ofethylenetoacetaldehydein the presence of cupric chloride. The palladium is presumed to be repeatedly ...
Analysis of variance (two-way ANOVA) of the experimental data was performed using IBM SPSS Statistics 20 for Windows (SPSS Inc., Chicago, IL, USA). To separate treatment means within each measured parameter, Duncan’s Multiple Range Test (DMRT) was performed at p≤ 0.05. Principal component...
Thallium metal has no commercial use, and thalliumcompoundshave no major commercial application, since thallous sulfate was largely replaced in the 1960s as a rodenticide andinsecticide. Thallouscompoundshave a few limited uses. For example, mixed bromide-iodide crystals (TlBr and TlI) that transmit...
Several studies have demonstrated that oxidation can be useful for soils and oily-sludge treatment. Watts and Dilly (1996) investigated a number of iron catalysts [iron (III) perchlorate, iron (III) nitrate, iron (III) sulfate, iron (II) perchlorate, iron (II) sulfate, and an iron (III)...
The exception was for the 20 µg/kg dose group at 120 minutes, however by 24 hours, pupillary constriction was comparable with the lower dose groups.” “When atropine sulfate and pralidoxime chloride were administered together, they significantly protected pupillary constriction by 30 minutes ...
Since this method is rather tedious and considering the optical properties of dichromate and trivalent chromium ions, CR2O7− and Cr3+ (this last form resulting in the reduction of dichromate during the oxidation of organic matter), several UV–visible spectrophotometric methods were proposed for ...
Metal-catalysed oxidation of proteins varies in selectivity and depends on the surface residues to direct the reaction. Here, the authors use polyoxometalate clusters as inorganic ligands for Cu ions, enabling the regioselective oxidative cleavage of a protein via reactive oxygen species in the vicinity...
The utilization of dyes in textile industries has enormously increased in recent years and has created several environmental problems. Currently, several m
