Gravimetric determination of caesium and potassium with sodium triphenylcyanoborate (caesignost).
Caesium can be determined gravimetrically with sodium triphenylcyanoborate (Caesignost) as precipitant. The precipitation was checked by addition of (137)Cs tracer and gamma-spectrometry. The following parameters were studied: temperature, digestion time, influence of potassium on the precipitation of caesium, and separation of caesium from bulk quantities of potassium.
