Abstract

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.
