The Determination of Volatile Free Acids in Sewage by Gas Chromatography Using an Internal Standard Method.

Abstract

During the anaerobic production of methane gas from sewage, low molecular weight organic acids are also produced. Knowledge of the concentration of these acids is critical in order to maintain digester equilibrium. A method is described for the determination of volatile free acids by gas chromatography using an internal standard. (Author)
