Alcohols Traces Checked in River and Rain Water Using a DMFC-Enzymatic Device

Abstract

Using direct methanol fuel cell (DMFC) with alcohol dehydrogenase enzyme inserted in the anodic site by mean of a small dialysis bag, alcohol (ethanol and methanol) traces have been determined in rain and river natural waters. These two latter different type of natural waters have been also well distinguished using PCA and by performing additional measurements of pH, temperature, and oxygen content.
