摘要：

A procedure is reported for the determination of Fe in high-purity POCl3 at a concentration level of 10-80 mu g l(-1). Electrothermal atomic absorption spectrometry was used and liquid POCl3 was directly injected into a graphite tube of the atomizer. The optimum operating conditions of thermal pre-treatment and atomization steps were established. A calibration line based on the analysis of FeCl3 solutions in water can be used for the determination of Fe in POCl3 with good accuracy.
