摘要：

The determination of sulfur dioxide in wines by flow injection analysis is described. The method is based on a dual electrochemical system, the upstream electrode being a coulometric electrode that eliminates interferences prior to the detection of the analyte at an amperometric electrode. At least 30 wine samples per hour can be determined by this procedure, and the results for free and total sulfur dioxide concentration in white wines compare favorably with those obtained by the standard aspiration-oxidation method.
