Fluorometric determination of sulfites in rainwater
1986
Analytical Sciences
A simple and specific fluorometric determination of sulfites in rainwater was developed. Rainwater was collected in the field in a trapping buffer containing EDTA (pH 10.0), which effectively prevented the loss of sulfites by oxidation. Then its aliquot was labeled with N-(9-acridinyl)maleimide (NAM) and the concentration was determined on a high performance liquid chromatograph equipped with a fluorometer. The concentration range of the determination was about 1.0-100 pmol on column. The
