Determination of carbofuran by flow‐injection with chemiluminescent detection

It was found that carbofuran enhances the chemiluminescence reaction between sodium sulphite and Ce 4+ in sulphuric acid, and this formed the basis of a flow‐injection system with chemiluminescence detection for determination of carbofuran. Under optimum conditions, the enhanced chemiluminescence intensity was linear, with the concentration of carbofuran in the range 8 × 10 −8 –1.0 × 10 −5 g[sol ]mL, with a detection limit of 2.84 × 10 −8 g[sol ]mL (3 s[sol ]k). The proposed method was applied to the analysis of carbofuran in cabbage, with satisfactory results. Copyright © 2005 John Wiley & Sons, Ltd.
