Destruction of complexants used in groundwater decontamination
Description
A supported liquid membrane process is being developed to remove uranium from aqueous solutions. The uranium would be concentrated into a strip solution containing either vinylidene-1,1-diphosphonic acid (VDPA) or 1-hydroxyethane-1,1-diphosphonic acid (HEDPA). This study compares the degradation of HEDPA and VDPA under similar conditions. For the time of the tests in this study (3 h) the maximum amount of HEDPA that was destroyed was 83.5% using hydrogen peroxide and the maximum amount of VDPA destroyed was 64.6% using nitric acid
