摘要

Abstract

A new convenient sulfide electrochemical sensor for marine environmental in-situ monitoring and real time survey was developed. The new sensor based on a solid Ag2S membrane electrode has outstanding chemical sensitivity and stability. It responds to the activity of sulfide ions according to a Nernstian slope of −31mV/decade. The sensor can be used to determine the total concentration of sulfides (C T) by calibrating the pH value of the solution to a standard pH. The practical measurement range for total sulfide concentration is 0.1–10 mg/L in seawater. The sensor has a very low potential drift (<4 mV) during two months in 0.1 mg/L sulfide seawater. This paper describes the preparation of the sensitive membrane and some main properties of the sensor.
