Extraction of strontium from nitric acid solutions by selected crown ethers

Creators

Description

The extraction of Sr from nitric acid solutions by the crown ethers, 12-crown-4, 15-crown-5, Db 18-crown-6 and 18- crown-6 diluted with chloroform was investigated. It was found that Sr is more extracted by 18-crown-6 than the others crown ethers from different nitric acid solutions. The extraction is strongly dependent on the concentration of H NO3 and nitrate salts. Addition of Mg(No3)2 leads to a slight increase in the distribution ratio. Preliminary studies indicated that Cs-137 is also extracted to a limited extent by 18-crown-6 or Db 18-crown-6 from nitrate medium. stripping of Sr was achieved by aqueous solution of low acidity. 1 tab., 5 fig
