Spectrophotometric flow-injection determination of sulphite in white wines involving gas diffusion through a concentric tubular membrane
A flow-injection system is proposed for the spectrophotometric determination of sulphite in white wines. The method involves analyte conversion to SO2, gas diffusion through a Teflon® semi-permeable membrane, collection into an alkaline stream (pH 8), reaction with Malachite green (MG) and monitorin...
