Ammonium nitrate (AN) is an inorganic crystalline compound used as a solid propellant oxidizer and as a nitrogenous fertilizer. The practical use of AN as solid propellant oxidizer is restricted due to the near room temperature polymorphic phase transition and hygroscopicity. A good deal of effo...

The effects of added potassium ferrocyanide (CN) in different concentrations (2.5 ppm, 7.5 ppm and 100 ppm), in salt, on lipid oxidation in cod during salting, storage and rehydration were examined in this study. An increase in CN concentration accelerated lipid oxidation of the salted cod, as o...

EPR spectra were obtained for the type 2 Cu(2+) site in particulate methane monooxygenase, pMMO, from membrane fractions of Methylomicrobium album BG8. In addition to the EPR signal with g‖=2.24 and A‖=185 G found in both cells and membrane fractions, a second EPR signal with g‖=2.29 and A‖=...

The occurrence of ferrocyanide, Fe(CN)64−, in aqueous environments is of concern, since it is potentially hazardous. For tracing the source of ferrocyanide in contaminated water we developed a method that relies on the determination of the stable isotope ratios of 13C/12C and 15N/14N of this com...

An aqueous dispersion of cupric ferrocyanide is found to photogenerate hydrogen and oxygen with visible light under sacrificial conditions without the necessity of having electron or hole transfer agents. The mechanism involved is discussed.

A new biometallization route for detecting low levels of organophosphorus nerve agents based on organophosphorus-hydrolase (OPH)-stimulated formation of cupric-ferrocyanide (CuFeCN) nanoparticles is described. The growth and accumulation of these nanoparticles onto the surface of carbon paste el...

In this technical note, the adsorption of the gold–thiosulfate complex ion ([Au(S2O3)2]3 −) on cupric ferrocyanide (CuFC)-impregnated activated carbon in aqueous solutions was investigated to identify a better adsorbent for the gold thiosulfate process. This study was performed using cupric fer...

Lipid peroxidation of brain lipids as determined by the conjugated diene method was observed in mice following administration of sublethal doses of potassium cyanide (KCN). Conjugated diene production was dose- and time-dependent; 10 mg/kg KCN produced detectable levels of conjugated dienes at 3...

Chronic implantation of surface coils on the skull has been developed to record 31P NMR spectra of the brain in unanesthetized rats. Intraperitoneal sublethal potassium cyanide doses induce strong and reversible changes in high-energy phosphate compounds in the brain, similar in part to those in...

α-Ketoglutaric acid (α-KG) has been shown to be an effective antagonist for cyanide-induced lethality. The mechanism of this antagonism is hypothesized to result from α-KG binding with cyanide. Several investigative approaches were taken to determine the existence of this binding. First, mixt...

Catalytic activity of a series of Fe–Zn double-metal cyanide (DMC) complexes with varying structural and acidic properties has been investigated for the synthesis of hyperbranched polyesters (HPs) from glycerol and succinic acid/adipic acid. The DMC complexes were prepared using different compl...

In highly aerobic environments, Gluconacetobacter diazotrophicus uses a respiratory protection mechanism to preserve nitrogenase activity from deleterious oxygen. Here, the respiratory system was examined in order to ascertain the nature of the respiratory components, mainly of the cyanide sensi...

The effect of potassium cyanide on p-nitroanisole O-demethylation in perfused rat livers has been examined. Cyanide (2 mm), an inhibitor of cytochrome oxidase, diminished p-nitroanisole O-demethylation by 50–75% in perfused livers from normal and phenobarbital-treated rats, but had much less ef...

Presence of heavy metals, phenols, and cyanides is highly dangerous, and in the simultaneous presence, the effect is compounded. Chemical precipitation of such pollutants from industrial waste has gained momentum in recent years, as it promise to surpass the major drawbacks laid by the other phy...

A study was undertaken to identify indigenous potassium solubilizing bacteria in southern Indian tea plantation soils. The samples were analysed for various soil edaphic parameters such as pH, Ec, water holding capacity, organic carbon, nitrogen, available phosphorous, exchangeable potassium, ex...

High purity potassium silver cyanide was prepared using air blasting cyanidation technique with environment amicability and lower cost. The size of silver powders has a significant effect on the speed of cyanidation, and controlling the crystallinity in the crystallization processes is the key f...

Potassium cobalt hexacyanoferrate was modified on alkali-hydrolyzed leather scrap (AHLS/KCoFC) to prepare a novel adsorbent for cesium (Cs+) adsorption. AHLS/KCoFC was characterized with SEM, FT-IR, XRD, and XPS to affirm the correct modification. Batch experiments were performed to investigate ...

SummaryThe Pallamet 600 process presents the advantages of both conventional ammoniacal and ammonia-free processes. The on-line ammonia odor in a production environment is dramatically reduced due to the extremely low free ammonia in the electrolyte. In addition, Pallamet 600 does not require an...

Finely divided crystalline palladium has been synthesized from several inorganic precursors by chemical reduction in ethylene glycol. Palladium black is produced when ethylene glycol serves as solvent and reducing agent. Monodisperse spherical particles are produced by the hydrazine reduction of...

The thermal dissociation of the palladium(II) tetrammine-complexes, [Pd(NH3)4]X (where X is 2Cl, 2Br, 2I, 2NO3, and SO4), was studied by thermogravimetry, DTA, GE, and by analysis of the pyrolysis products. The complexes, except for the nitrate and sulphate, dissociated to give the trans-diammin...
