Description
  • Elektroforéza ve volné kapalině byla použita pro studium komplexace thoria s huminovou kyselinou Aldrich (HA) s cílem vyzkoušet použitelnost této metody za obtížných podmínek a získat chybějící data o této komplexaci při nízkých hodnotách pH. Elektroforetická pohyblivost thoria značeného 234Th byla měřena ve vodných roztocích 0.01M (HClO4 + NaClO4) jako funkce pH (2-4), koncentrace thoria (Th  10-7 - 10-5 M) a koncentrace HA (0 - 10 mg/l). Bylo zjištěno, že sorpční ztráty thoria při elektroforéze nezabraňují stanovení zastoupení komplexů ThHA a jejich střední pohyblivosti s přijatelnými chybami. Byly stanoveny většinou vysoká zastoupení a záporné pohyblivosti těchto komplexů. (cs)
  • Free-liquid electrophoresis was used for the study of thorium complexation with Aldrich humic acid (HA) with the aim to test applicability of the method under difficult conditions and to obtain missing data on the complexation at low pH values. Electrophoretic mobility of thorium labelled with 234Th was measured in aqueous solutions of 0.01M (HClO4 + NaClO4) as a function of pH (2-4), concentration of thorium (Th  10-7 - 10-5 M) and concentration of HA (0 - 10 mg/l). It was found that sorption losses of thorium during electrophoresis do not prevent determination of abundance of ThHA complexes and their mean mobility with acceptable errors. Mostly high abundances of the complexes and their negative mobilities were determined.
