Preparation of nano gold powder from acid leaching tail solution
According to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. The low value residual gold ions existed in acid leaching tail solution in Mouteh gold mine in Iran with fellow heavy metals as pollutants (Fe2+, Cu2+, and Zn2+). Preparation of nano gold particles is achieved by two steps: First, by addition of ammonia as separatio...

متن کاملDetermination of condensed tannin monomers in environmental samples by capillary gas chromatography of acid depolymerization extracts
A method for molecular-level quantification of condensed tannin is described that uses acid depolymerization and carbocation capture by phloroglucinol. Resulting monomers and phloroglucinol adducts are trimethylsilyl derivatized, separated by capillary gas chromatography, detected by flame ionization, and quantified relative to standards. Optimal depolymerization conditions were determined for ...

متن کاملResearch Note Intake of Water Containing Condensed Tannin by Cattle and Sheep
Ingestion of small amounts of condensed tannin (CT) by ruminants can prevent bloat, improve nitrogen retention, and reduce excretion of urea, a precursor of ammonia and the greenhouse gas nitrous oxide. Because grasses and many forbs don’t contain CT, it is desirable to find a reliable way to have ruminant livestock ingest small amounts of CT when they consume high-quality forage. Putting CT in...
