Imferon (Merrell-National), an iron-dextran complex, is widely used in patients with iron deficiency. It is present in the circulation in appreciable amounts for two to three weeks after administration and interferes with all tested colorimetric iron assays, both with and without deproteinization. The amount of the plasma Imferon iron interference depends primarily on the choice of reductant. W...

Abstract The preparation of ammonium ferrous sulfate is a typical comprehensive experiment in inorganic chemistry universities, and also an important part the laboratory technology project National Vocational Skills Competition. synthesis method constantly improving. traditional was studied by reduction green modification, purity product analyzed spectrophotometry. results show that optimal exp...

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...

Abstract Sulfate is present in all freshwater and marine environments reduced to toxic corrosive hydrogen sulfide by anaerobic bacteria. By measuring depth profiles of sulfate sediments, it possible obtain estimates reduction rates (SRRs). A whole‐cell microscale biosensor for was constructed placing a mixture sulfate‐reducing aerobic bacteria front microsensor. The were supplied with electron ...

Two rumen nitrate-reducing isolates of Desulfovibrio desulfuricans were found to hydrolyze cysteine with the production of sulfide and pyruvate. When cultured on agar medium containing yeast extract with nitrate as the primary electron acceptor and ferrous chloride as the indicator, blackening of colonies occurred. The blackening of colonies appeared sooner and was more intense when either cyst...

Treatment of coenzyme Q with ozone, permanganate, and ferrous sulfate in presence of ascorbate or hydrogen peroxide yielded water-soluble degradation products, possibly having truncated side-chain and modified ring.These derivatives, but not the intact lipid-quinone, showed relaxation of phenylephrine-contracted rat arterial rings. Representative samples of these also decreased blood pressure w...
