Abstract
The period of retention of liquid in a laboratory-scale percolating filter was determined using six radioactive tracers and one chemical tracer. Of the radioactive tracers it was found that adsorption of Na 24, Rb 86 and K 42 was too great for them to be of use. With bromide-Br 82, tritiated water and cobalticyanide labelled with Co 58 or Co 60, more satisfactory results were obtained. Of these tracers, cobalticyanide appeared the most suitable, taking into account half-life, adsorption and ease of counting.
