Abstract: This paper reports on a desiccated full evaporation headspace gas chromatographic (FE HS-GC) technique for determination of the methanol content in dilute mill effluents. Anhydrous K(2)CO(3) was selected as the preferred salt for eliminating the water in the sample in the headspace sample vial. The results showed that the addition of 12 g K(2)CO(3) made it possible to introduce a larger sample size (up to 1 mL) into the FE HS-GC measurement, thereby increasing the sensitivity of the technique. At the given equ…
