▎ 摘　　要

NOVELTY - Analysis of metals retained in magnetic sorbents involves performing atomic absorption spectrometry characterized by direct insertion into flame or into atomizing tubes over flame. USE - Analysis of metals e.g. lead and cadmium (all claimed) retained in magnetic sorbents dispersed in aqueous sample. ADVANTAGE - The method enables simple, easy, economical, efficient, environmentally-friendly and rapid analysis of metals retained in magnetic sorbents dispersed in aqueous sample, with high sensitivity and analytical detectability. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining the analysis of metals retained in magnetic sorbents dispersed in aqueous sample by atomic absorption spectrometry.
