ABSTRACT
<p><b>OBJECTIVE</b>To establish a derivative fluorometry method for the determination of sulfur dioxide residues in traditional Chinese medicine.</p><p><b>METHOD</b>The optimal derivation condition was established. The fluorescence intensity was detected at excitation wavelength of 321 nm, and emission wavelength of 384 nm.</p><p><b>RESULT</b>A linear relationship was obtained between the fluorescence intensity and the addition of reference substance in the range of 0.999 7-17.99 nmol with a correlation coeffient of 0.999 9, and the average recovery was 102.3% with RSD 4.6%.</p><p><b>CONCLUSION</b>This method is simple and sensitive with quick and correct result. It can provide a reference for the determination of sulfur dioxide residues in traditional Chinese medicine.</p>
