A simplified titrimetric method for potassium is proposed. In the usual method, potassium is precipitated by sodium tetraphenylborate and the excess of the reagent is back-titrated with a quaternary ammonium salt, but the precipitate must be removed to prevent the reaction between the precipitate and the titrant. Polyvinylpyrrolidone can be used to deactivate the precipitate so that it need not be removed.
