We have used size exclusion chromatography SEC and asymmetrical flow field-flow fractionation (As-FFFF) coupled with refractometry (RI), multi angle laser light scattering (MALLS), ultraviolet (UV) and inductively coupled plasma mass spectrometry (ICP-MS) detectors to study colloidal binding of uranium in leachates. The nature, the molecular and size distribution and the quantitative uranium distribution over the colloidal phase are obtained
