[Determination of alkali-earth metal by microwave plasma torch atomic emission spectrometry].
Determination of alkali-earth metal by microwave plasma torch atomic emission spectrometry (MPT-AES) was investigated. Operating conditions the effects of some coexistent elements were examined. Detection limits for Be, Mg, Ca, Sr and Ba are 0.47, 1.4, 0.15, 0.20 and 2.6ng/mL, respectively. Method has been applied to analyse some actual samples with satisfactory results.
