An investigation into the chemiluminescence of fourteen organic acids and tris(2,2'-bipyridyl)ruthenium(II) was undertaken. Particular emphasis was placed upon the method of production of the reagent, tris(2,2'-bipyridyl)ruthenium(III), with cerium(IV) sulfate, potassium permanganate, lead dioxide and electrochemical generation. Analytically useful chemiluminescence was observed when Ce(IV) or ...

Commonly, the agricultural waste, i.e. lignocellulosic biomass is disposed through combustion causing air pollution with production of PM2.5 and PM10 particles. However, it has been found that these biomasses can be used as source for biofuels other valuable biochemicals. Though deconstruction challenging due to its complex structure. In this study, rice straw (RS) was pretreated using potassiu...

Oxidation–reduction titrations and potentiometric methods provide a convenient experimental means to quantitatively determine compositions of unknown mixtures containing oxidizable/reducible species. Over the past decade, numerous titration methods have appeared in this Journal (1–6) and in standard laboratory manuals (7–10) involving common titrants such as potassium dichromate, iodine, potass...

and it loses oxygen rapidly in oxidizing organic matters. Moreover, it is costly to use. But it has got an important advantage and that is, it is a stable compound. Potassium permanganate is generally used by adding the chemical to the water in such an amount which will produce some pink colour. But the practical details of its use are different in different places in India. For example, in the...

Heavy nitrogen (N2) 1 is often used as a label for nitrogen Wxation experiments in which it is desirable to monitor directly the rate of nitrogen Wxation and the destination of the resulting metabolites in an organism or ecosystem [1–4]. Heavy nitrogen can be purchased in a pressurized cylinder or produced in the laboratory with specialized equipment, but both methods of obtaining the gas are e...

The far upstream element (FUSE) of the human c-myc proto-oncogene stimulates expression in undifferentiated cells. A FUSE-binding protein (FBP) is present in undifferentiated but not differentiated cells. Peptide sequences from the purified protein allowed cloning of cDNAs encoding FBP. Expression of FBP mRNA declined upon differentiation, suggesting transcriptional regulation of FBP. Features ...

In a series of five tests, liquid polyphosphate fertilizer solution was used to treat liquid dairy and swine manure to control odors. Potassium permanganate, a pesticide-wetting agent, nitrogen-zinc liquid fertilizer solution and a digestive deodorant were also used in several of the tests. All tests were evaluated by an odor panel for odor strength and odor quality. The polyphosphates did not ...

A simple, rapid and highly sensitive spectrophotometric method is developed for the determination of risperidone in tablet formulation. The method is based on the oxidation of drug using potassium permanganate in alkaline medium and excess potassium permanganate oxidizes 1,10-phenanthroline Fe(II). The measurement of decrease in absorbance of 1,10-phenanthroline Fe (II) was done at 415 nm. The ...

The external microbiome of fish is thought to benefit the host by hindering the invasion of opportunistic pathogens and/or stimulating the immune system. Disruption of those microbial communities could increase susceptibility to diseases. Traditional aquaculture practices include the use of potent surface-acting disinfectants such as potassium permanganate (PP, KMnO4) to treat external infectio...
