Abstract
The dinonylnaphthalene sulfonic acid (HD) forms micelles in non-polar organic solvents, and can be used as an analogues of cross-linked resinous strong acid cation-exchangers. Since HD shows strong ex traction of metals from the aqueous phase to the organic phase, it has been used by the authors in bio-assay studies for the determination of gross alpha activity in urine. Based on this experience the HD has again been studied for the determination of uranium concentration in environmental samples which will be described below.
Dinonylnaphthalene sulfonic acid (HD) effectively determines environmental uranium concentrations in air, sea water, and soil, with potential applications in bio-assay studies for gross alpha activity in urine.
