"Determination Of Sulfur Dioxide In Wines By Gas-diffusion Flow Injection Analysis Utilizing Modified Electrodes With Electrostatically Assembled Films Of Tetraruthenated Porphyrin"

Abstract: Reported is a new method for the determination of both Gee and total SO2 in wine, specially designed for FIA. The method involves separation of the analyte using a flow-through gas diffusion unit, in line with an amperometric detector consisting of a glassy carbon electrode modified with electrostatically assembled films of a tetraruthenated porphyrin. The results demonstrate a good accuracy, comparable with those obtained using the conventional iodometric method. In addition, the method can be readily applied to red, white and rose wines; it is free from interference of the other compounds of wine, consumes small amounts of sample and is faster than the iodometric method.
