Radioactive Tracer
-
-
Adsorption
-
Amount of radionuclide in the solution in low but in principle,
all the radioactive atoms could be adsorbed on the walls of the vessel
depends on the concentration, on the chemical state of the radionuclide
and on the nature of the container material
Radiocolloids
-
Solution contains large molecules such as polymeric hydrolysis
products,tend to adsorb trace elements.
Dust, cellulose fibers, glass fragments, organic materials
Colloids
Mixture containing small particles, in the range of 10-1000nm
that do not dissolve in the solution.
Equilibrium reactions
Low concentration of radioactive tracers lead to the formation of solute species
that are not observed at equilibrium with macro amounts.
Trace metal concentrations used to study the properties of a metal ion at relatively high pH's without the interference of polymerization reactions
