Summary

The results of a study of the chloroform extraction of mercury(II) from aqueous nitric acid and nitrate ion solutions employing 4-hep-tanone oxime as a complexing reagent are outlined. The effects of nitric acid, sodium nitrate, lithium nitrate, 4-hep-tanone oxime and mercury(II) concentrations are described. Measurements of recovery factors indicate that greater than 99% of the mercury(II) taken at the 100 mg level per 50 ml of aqueous solution can be extracted.

Zusammenfassung

Die Ergebnisse der Chloroform-Extraktion von Hg(II) aus wäßriger Salpetersäure und Nitratlösungen mit 4-Heptanonoxim als Komplexbildner wurden mitgeteilt. Der Einfluß der Salpetersäure, des Natriumnitrats, des Lithiumnitrats, des 4-Heptanonoxims und der Hg(II)-Konzentration wurden beschrieben. Messungen des Wiederfindungs-Faktors zeigen, daß mehr als 99% des eingesetzten Quecksilbers in der Größenordnung 100 mg/50 ml wäßriger Lösung extrahiert werden.
