Wet Digestion, also called acid digestion,
refers to the conversion of the components to be tested in a sample containing
a large amount of organic matter under heating with a mixture of different
acids or mixed acids or hydrogen peroxide or other oxidizing agents. It is a
method for determining the morphology (the organic substance in this process is
decomposed and oxidized into CO2, water and various gases). Wet Digestion is
popular in laboratory experience as a direct, effective and economical sample
preparation method for elemental analysis. It can handle a large number of
samples simultaneously with easy operation.
