摘要：

An energy dispersive X-ray fluorescence method for the measurement of pollutants in plant material is described. The measuring system consists of a Si(Li) detector, **1**0**9Cd and **5**5Fe annular sources and a multichannel analyser with a built-in minicomputer. The methods of calibration and standard preparation are discussed. Plant material is analysed either as dried and pressed pellets or as ash after combustion of the sample. The results of the analysis of moss samples are reported. Sulphur contents of beech leaves and pine tree needles are determined by using the internal standard method. The XRF method proved to be useful and sensitive enough to measure pollution of plant material.
