摘要:
The extraction of strontium picrate with various open-chain ether dicarboxylie acid diamides, ether dicarboxylie monoamido acids and N-alkyl imino diacetic diamides has been investigated. The influence of pH, diluents and counter anions on the extraction equilibrium was studied. The extraction results are discussed in relation to the structure of the investigated amido podands and compared with crown compounds and open-chain structure analogous. The performed investigations show clearly the amido group is decisive for the extraction properties.
