• In order to establish a reliable and rapid method for the determination of rubidium in biological materials using atomic absorption spectroscopy, chemical interference as well as ionization interference due to co-existing elements and some organic substances was studied. In the presence of potassium of sufficient concentration, most of the interference was found to be negligible. The temperature of the sample solutions proved to be a possible source of error. The process of sample preparation was examined, including a determination of the loss of rubidium in dry ashing. The accuracy and precision of the method was tested by analyzing NBS SRM 1577 Bovine Liver. The rubidium contents of typical biological materials—foodstuffs, human tissues and urine— were determined by the present method and a possible relationship between the rubidium and potassium concentrations is indicated.
