| titleOfInvention | Rapid Determination of Volatile Fatty Acids in Sludge |
| abstract | The invention provides a rapid determination method for volatile fatty acids in sludge, which belongs to the field of compound analysis and detection, and can solve the problem that in the existing gas chromatography, samples need methyl esterification, extraction, etc., resulting in increased determination steps, cumbersome, long time, and determination results. technical issues such as inaccuracy. The technical scheme includes: after the sludge anaerobic fermentation broth is subjected to centrifugation, filtration and acidification treatment in sequence, a sample to be tested is obtained, and the acidification treatment is performed with phosphoric acid; the sample to be tested and a fatty acid standard sample are measured by gas chromatography to obtain the measurement result; Compare the retention time of the sample to be tested and the fatty acid standard sample for fatty acid characterization; substitute the measured results of the sample to be tested into the formula for calculating the fatty acid content to obtain the actual content of fatty acids in the sludge. The invention not only has the characteristics of simple operation, fewer steps, rapidity, accuracy, and less sampling amount, etc., but also does not need methyl esterification and extraction, directly injects samples, and greatly reduces the amount of organic solvent used. |
