摘要：

A macrocyclic molecule, the calix[6]arene 4(6), functionalized with carboxy groups, has been studied and its extraction efficiency towards uranium determined in a two phases solvent-extraction system. Two solvents, dichloromethane and benzene were used to follow uranium extraction from media containing sodium ions. The study of the extraction parameters allowed proposing an extraction scheme with each solvent. The extraction efficiency was found to increase with pH, with an optimal efficiency of nearly 100%. No decrease of uranium extraction was observed in synthetic solutions containing sodium ions (spiked with Na-22) and/or Pu-239. Under specific conditions, almost 100% of uranium have been extracted by the calixarene from real urine samples.
