| Abstract: | A modified steam distillation method for the accurate determination of low levels of volatile acids found primarily in low rate anaerobic digestors has been developed. The interference of bicarbonate alkalinity is minimal with complete removal of carbon dioxide from the sample prior to distillation. This removal can be achieved by boiling the acidified sample for 30 min in an erlenmeyer flask with ground‐glass neck attached to a reflux condenser. |
