Am looking for the best method for organic acids extraction from soil samples taken from field trials? I will be using the Reverse Phase HPLC for their determination. Thanks for your suggestions.
One of the methods involves the release of organic acids by PSB to dissolve insoluble P , including malic, lactic, acetic, citric etc.The soil samples were collected from the rhizosphere and Chinese cabbage plants grown in Yangling at a depth of 15 - 20cm. HPLC analysis can be used to detect soil organic acids. the method of extraction is the closed system Purge and trap and extraction for volatle organics in soil and water systems.
