Multielement analysis of gypsiferous soils using a sequential inductively coupled plasma-atomic emission spectrometric method

The amount of major, minor, and trace elements (Ca, Mg, Fe, Na, Sr, Mn, Cu, Cr, V, Mo, B, Ni, Li, and Ba) in gypsiferous soils formed by evaporitic processes was determined. A sequential analysis method by atomic emission spectroscopy with an inductively coupled plasma was used, working with partial matrix matching between the reference standards and the real samples. Furthermore, a simplified method, based on two calibration graphs (Fe and Li), was developed for calibrating the analysis procedure.
