EN

Pb, Mg and Ca were simultaneously determined in plant roots by slurry introduction into inductively coupled plasma optical emission spectrometry (SS-ICP-OES). Slurries were prepared in 0.5% or 5% (v/v) HNO3 with 0.5, or 5% (v/v) Triton X-100. Omission of the Triton X-100 improved results. Compared with wet ashing of the root sample followed by ICP-OES, ICP-MS and FAAS, the method offers: comparable results, simplification of sample preparation, less sample contamination, and reduction in the use of dangerous and corrosive reagents. The precisions varied: 1.7% for Mg, 2.8% for Ca and 4.3% for Pb, and were not significantly different (95% confidence level) from those of conventional analysis. [...]
