摘要：

A chemical oxygen demand sensor employing a thin layer electrochemical cell was constructed using a sandwich-type thin layer working electrode. The electrode was constructed by attaching face to face glass and copper plates separated by PTFE spacers to create an extremely shallow cell. After filling the cell by capillary action, it was possible to measure reproducibly the coulometric charge required for exhaustive electrolysis, with a single measurement taking 3-10 min according to the kind or the concentration of the sample. The results obtained are compared with those obtained in our former work using the same standards and real samples from lakes. A new artificial water sample was found to behave similarly to real samples. (C) 1999 Elsevier Science B.V. All rights reserved.
