A COMPARATIVE STUDY OF INDUCTIVELY COUPLED PLASMA OPTICAL EMISSION SPECTROMETRY AND MICROWAVE PLASMA ATOMIC EMISSION SPECTROMETRY FOR THE DIRECT DETERMINATION OF LANTHANIDES IN WATER AND ENVIRONMENTAL SAMPLES
Published: 28 May 2015
Abstract: A new instrumental technique – Microwave Plasma Atomic Emission Spectrometry (MP-AES) is compared to conventional Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) for direct determination of lanthanides. Estimation of both methods is done using standard measurement conditions. The present study includes spectral and non-spectral matrix effect evaluation. Tested analytical wavelengths of lanthanides are divided into three groups: 1) relatively free, 2) interfered by other lanthanides and 3) interfered by concomitant elements. Non spectral effect on analytes is examined in two typical real matrices – acidic plant digests and saline water. The capabilities of both plasma methods for quantitative determination of La, Ce, Sm, Eu, Gd and Er are compared. The interference-free emission lines are selected; appropriate background correction is proposed and the corresponding instrumental detection limits are calculated.
