Extraction of metal ions from chloride solution with N,N-dioctylacetamide.
N,N-Di-n-octylacetamide (DOAA) was prepared and shown to be an effective extractant for a number of metal ions from aqueous hydrochloric acid solution. Distribution ratios of 35 metal ions were measured for 1M DOAA in chloroform and hydrochloric acid solutions ranging from 0.10 to 9.0M. Extraction of uranium(VI) from solutions of hydrochloric acid and of nitric acid was compared. The effects of different diluents and varying concentrations of DOAA were studied in an attempt to elucidate the extraction mechanisms involved.
