The use of calix[6]arene molecules for actinides analysis in urine and drinking water: an alternative to current procedures

In this work the applicability of calix[6]arene columns for actinides analysis in urine samples and drinking water was investigated. A radiochemical procedure has been developed for U, Pu, Am analysis in urine. A simple and effective method has also been proposed on a specific column named AQUALIX, for the separation and preconcentration of U from drinking water. These procedures are suitable for routine analysis and require a considerably reduced number of steps of sample treatment as compared to current procedures.
