Disk mini-adsorbers with radial flow for determination of [sup.234]Th concentration in seawater

Disk mini-adsorbers with radial flow for determination of [sup.234]Th concentration in seawater

A modified method has been developed for measuring the [sup.234]Th concentration in seawater, which is based upon the use of Mn[O.sub.2]-impregnated disk mini adsorbers with radial flow connected in-line and the direct beta counting of [sup.234]Th and/or its daughter [sup.234]mPa. This allows determ...

description A modified method has been developed for measuring the [sup.234]Th concentration in seawater, which is based upon the use of Mn[O.sub.2]-impregnated disk mini adsorbers with radial flow connected in-line and the direct beta counting of [sup.234]Th and/or its daughter [sup.234]mPa. This allows determining the [sup.234]Th concentration in a relatively small volume of seawater (20-50 L) with the possibility to check the extraction efficiency in every individual sample. The field testing, which was carried out at different areas of Sevastopol Bay during different seasons, has shown applicability of the proposed method to evaluate particle fluxes in marine environments within a wide range of concentrations of suspended matter.
