Coprecipitation Of Metal Salts With Organic Coprecipitants, Omar E. El-Arini
Coprecipitation Of Metal Salts With Organic Coprecipitants, Omar E. El-Arini
Masters Theses
"Coprecipitation studies were carried out for the more insoluble salts of six common metals and five anion systems. Three metal sulfides, namely, CuS, CdS and NiS, were the only metal salts studied that indicated nearly complete coprecipitation with phenolphthalein as carrier precipitate. The same salts showed almost no coprecipitation with B-naphthol as carrier precipitate. Solvent extraction of CuS with chloroform showed no significant amount of extraction had taken place. The data obtained in this work did not disclose any relationship between the extent of coprecipitation and the solubility product constant of the salt present. The main difficulty encountered at this …
