Production and degradation of aerosols - hydrolysis behaviour of actinoids set free from solutions; stability investigations in high-temperature processes; Untersuchungen ueber Bildung und Zerfall von Aerosolen - das Verhalten hydrolysierender Actinoide beim Austrag aus Loesungen und Stabilitaetsuntersuchungen bei Hochtemperaturprozessen

Abstract

The aerosol production by bubble bursting in nitrate solutions of neodymium and Zirconium was investigated at different pH. Nd and Zr were chosen to simulate the hydrolysis behaviour of homologeous tri- and tetravalent actinoides. As a reference representing nonhydrolising elements Cesium was added to the solutions. Raising the pH led to an increased output of Nd and Cs or Zr and Cs, respectively, but no enrichment of one of these elements in the aerosols was observed compared to the composition of the bulk solutions. As the solutions became turbid, indicating the formation of colloids of Nd and Zr, an enrichment of these elements versus Cesium occured. With increasing precipitation this enrichment was lowered again. As explanation of these effects a simple model is proposed based on the suggestion of an enrichment of colloids in the bubble shell.
