title: Determination of carbofuran by flow-injection with chemiluminescent detection.
abstract: 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 x 10(-8)-1.0 x 10(-5) g[sol ]mL, with a detection limit of 2.84 x 10(-8) g[sol ]mL (3 s[sol ]k). The proposed method was applied to the analysis of carbofuran in cabbage, with satisfactory results.
