| Abstract: | Ionic absorption spectrometry using the inductively coupled plasma (ICP) as an ionization source and a 150 W stable xenon arc lamp as a light source has been investigated. A high-resolution echelle spectrometer was used for the absorption measurement. Ionic absorption lines in the wavelength region above 320 nm showed high sensitivity and detection limits of Y, Ti, Zr, Sc, Ce and La were of the same order of magnitude as those attained by ICP atomic emission spectrometry. Linear dynamic ranges of three orders of magnitude were observed for most elements tested. Effects of the measurement conditions such as rf power, outer gas flow rate, inner gas flow rate and observation height on the transmittance of the beam through the plasma and the absorbed radiation power of the analytes are also given. |
