摘要：

A new and simple amperometric sensor for sulfur dioxide (SO2) has been constructed based on the self-assembly of (3-mercaptopropyl)-trimetboxysilane (MPS) over a glassy carbon (GC) electrode followed by the complexation with silver. The silver dispersed onto the self-assembled surface exhibited excellent electrocatalytic activity for the determination of sulfur dioxide at a reduced potential (+0.3 V) with good sensitivity in a wide concentration range from 0.6 to 88 ppm with a correlation coefficient of 0.9989. The proposed sensor is easy to fabricate and has the advantages of good stability, reproducibility and rapid response. (C) 2002 Elsevier Science B.V. All rights reserved.
