The effect was presented for the determination of phosphorus with matrix modifier by graphite furnace atomic absorption spectrometry. It was found from results that Pd/Ca as a matrix modifier was more reasonable to determine phosphorus in animal and plant samples. The linear relationship between the absorbance and the concentration of phosphorus in the range of 0～20 μg/ml was obtained. The results were in good agreement with the reference and standard values.
