Microwave Digestion of Sewage Sludge accroding to EPA 3051A
For the digestion of sewage sludge in accordance with EPA 3051A, HNO3 is required. Alternatively, an acid solution consisting of HNO3 and HCl can be used in order to stabilize analytes such as Ag, Ba, Fe and Al. When using the speedwave XPERT for this digestion process, DAP-100X vessels are required. A detailed description on how to operate the digestion of sewage sludge in accordance with EPA 3051A can be found in the application note.
