Abstract

A study has been made or mineral acid matrix interferences in trace element determinations and methods are described for
the multi-element analysis of lichen and algae (blcmonitors) using Inductively Coupled Plasma Emission Spectrometry
(ICP-AES). Several calibration strategies were compared employing aqueous standards with and without acids using
modified rcp instrumental parameters. There was marked depression in analyte signal intensity in all the measurements.
It has been shown that signal depressions of up to 32% can be observed under normal operating conditions. The use ofacid
matrix-matched standards and internal standard for calibrations substantially reduced signal depression problem. The
methods gave elemental recovery from 97.7 to 98.8%. The accuracy otthc methods was assessed by anaiysing the certi-
fied lichen material from the International Atomic Energy Agency (IAEA). Accurate results were obtained by using the
above calibration strategy with improved precision.
