A method is proposed for determination of americium by coulometry. It is based on displacement of mercury(II) from its EDTA complex by americium and its subsequent electroreduction. The equivalence point is found by the "dead-stop" method. The cell and apparatus described will give a precision of about 0.1% for 700 mug of americium and 0.2% for 300 mug (relative standard error of the mean, 95% confidence) under optimum conditions. The measurement is absolute and prior standardization is not required. The determination takes about an hour. The results are compared with those obtained by other methods and interferences have been studied.
