THE SPECTROGRAPHIC DETERMINATION OF ALUMINIUM AND BERYLLIUM IN MAGNOX ALLOYS

OSTI ID:4242059
A method for the determination of aluminum and beryllium in Magnox aIloy was developed. The sample is dissolved in HCl, and the solution analyzed by the porous cup technique. Spectra are recorded by means of a Hilger Large Glass/ Quartz spectrographs and the plates evaluated by intensity methods. The method has been standardized to cover the concentration ranges in the alloy of 2.5 to 0.25% aluminum and 0.06 to 0.006% beryllium, but the sensitivity may easily be improved considerably. The approximate coefficients of variation (calculated for single exposures) are 2% for aluminum at the 1.0% level and 3.5% for beryllium at the 0.03% level. The method is simples precises and rapid; it is estimated that one operator may conveniently determine aluminum and beryllium in twenty samples within nine to ten hours, the maximum error being not greater than plus or minus 10%. Suggestions for future general investigation of the porous cup method are made. (auth)
