effect of zinc cyanide on protein and certain metabolites content and some enzymes activitieswas evaluated in liver, muscle and gill tissues of the freshwater fish, cirrhinus mrigala, during exposure andfollowing cessation of exposure. fish exhibited significant alterations in the biochemical parameters in alltissues studied. levels of total protein decreased in all tissues, where as free amino...

Wastewater discharged from metal-finishing processes usually contains cyanide, a hazardous substance that is used extensively in the surface finishing industry. In the present study, a synthetic solution resembling the contaminated wastewater was chemically treated using ferrous sulfate. This simple one-step process was applied successfully to remove cyanide from metal finishing wastewater. The...

cyanide (cn ) is a toxic species that is found predominantly in industrial effluents generated by metallurgical operations. cyanide’s strong affinity for metals makes it favorable as an agent for metal finishing and treatment and also as a lixiviate for metal leaching, particularly gold. these technologies are environmentally sound but require safeguards to prevent accidental spills from cont...

n-(7-chloro-1-methyl-2-oxo-5-phenyl-2,3-dihydro-1h-benzo[e][1,4]diazepin-3-yl)thiophene-2 carboxamide-[14c-carboxy] was prepared as part of a 6-step sequence from thiophene-2-carbonitrile -[cyano-14c] as a keysynthetic intermediate which has been synthesized from 2-iodothiophene and zinc [14c]-cyanide in thepresence of tetrakis (triphenylphosphine) palladium.

Superoxide dismutase has been studied in a wide range of organisms (Fridovich, 1975). Early observations suggested that superoxide dismutases isolated from eukaryotes (McCord & Fridovich, 1969; Misra & Fridovich, 1972; Beauchamp & Fridovich, 1973) showed little diversity in their properties, having mol.wts. near 32000 and containing two copper and two zinc atoms per molecule. The activity of th...

The pure rotational spectrum of the ZnCN radical in its X S ground electronic state has been recorded using millimeter/sub-mm direct absorption techniques in the range 339–543 GHz. This work is the first spectroscopic observation of this molecule, which was created by the reaction of zinc vapor and cyanogen gas in a dc discharge. Twenty-one rotational transitions were recorded for the main zinc...
