Ss. Biswas et al., DETERMINATION OF B AND CD IN MGF2 BY DC ARE OPTICAL-EMISSION SPECTROMETRY WITH ONLINE BACKGROUND CORRECTION APPROACH, INDIAN JOURNAL OF CHEMICAL TECHNOLOGY, 1(3), 1994, pp. 191-193
Using DC are optical emission spectrometry, B and Cd have been estimat
ed in MgF2 in the concentration range, 1-20 ppm. An on-line background
correction procedure has been developed to obtain net peak intensitie
s for B 249.77 nm, Cd 228.80 nm and Ga 241.87 nm (internal standard) l
ines. The background corrected peak intensities provided linear calibr
ation plots. The mean relative standard deviation of the method is fou
nd to be 11.1% for B and 9.8% for Cd.
