Radiotracer experiments on the model of rectangular settler with a volume of 3 m3, with a consecutive application as a tracer of the aqueous phase fluoresceine (representative tracer of water), eluate from a 68Ge/68Ga radioisotope generator (0.1 N HCl solution) and chelates after Ga ions complexation with 1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA) and 1,4,7,10-tetrazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) were carried out. The obtained residence time distribution (RTD) functions indicate that only the complex compounds of gallium are stable in the water phase and are not adsorb on the vessel walls, so they can be recommended as tracers of the water phase.
