ABSTRACT
The use of inductively coupled plasma atomic-emission spectrometry (ICP-AES) for the analysis of soil available sulphur

Inductively coupled plasma atomic-emission spectrometry (ICP-AES) parameters were optimized lar the determination of sulphur extractions from the soil with Ca(H2PO4)2 0.01 M. No spectral interferences were observad when using the 182.037 nm emission line. Recovery was not signilicantly different Irom 100% (P > 0.001). The detection and cuantilication limits were 0.3 mg/L and 1.5 mg/L, respectively. Coefficient of variation was less than 2.5%.

Keywords: soil, sulphur, spectrometry, inductively coupled plasma- atomic emission spectrometry (ICP-AES).
