摘要：

A new sulfite oxidase enzyme electrode for sulfite analysis in sea and river water samples was developed. The biosensor was constructed by coupling an oxygen sensor to a nylon membrane with the enzyme chemically immobilized on it. Measurement on standard solutions and in matrices of environmental interest were carried out both under steady-state and flow conditions. The possibility of employing fructose as stabilizing agent for sulfite both for standard solutions and aqueous environmental samples was also studied.
