Abstract
A 45% increase in current density was obtained by circulating the formate fermentation mixture through a perforated electrode, instead of using a static system. A current density of 19 mA/sq cm at a polarization of 0.15 V was obtained from a 0.03 M formate fermentation mixture at pH 1. The open circuit potential at this pH is -0.25 V vs. SCE. A new formic acid analysis, suitable for use with small amounts of fermentation mixtures, has been developed. It consists of two steps - vacuum distillation to separate the formic acid from interfering compounds, and oxidation to CO2 with Pb(OAc)4 to determine formic acid in the distillate. (Author)
