A method suitable for the routine determination of total carbon in uranium metal, titanium metal and steel has been presented, in which 90 μg to 500 μg of carbon is determined within 8 minutes.
The precisions attained by the following method are 2.2 μg, 4.9 μg, 4.7 μg, 4.7 μg and 7.4 μg in terms of standard deviation based on 93 μg, 190μg, 286Pμg, 385μg and 484μg of carbon, respectively.
The sample is burnt in an oxygen stream and the resulting CO2is absorbed in an absorber, containing 100mlof an absorbing solution and finely powdered BaCO3under vigorous agitation. The absorbing solution consists of 1-liter of N/1200 Ba(OH)2 and 1ml of iso-amyl alcohol as the surfactant.
The CO2absorbed is determined by using a high-frequency submersion type condenser electrode and a 30 mega-cycle oscillator.
The apparatus has been described and illustrated.
Analytical results on uranium metal, titanium metal and steels are given.
