A fast temperature programme for the determination of Pb in soil by slurry–electrothermal atomic absorption spectrometry was developed by omitting the charring step and drying at a higher temperature for a shorter time. The effects of drying temperature and time were systematically studied. Work with phosphate and Mg–Pd as chemical modifiers indicates that better results can be obtained without the use of modifiers.
