Poorly crystalline mineral phases stabilize soil organic matter: III. Effect of wet oxidation (NaOCl) on soil minerals

摘要

The data of dithionite and oxalate-extractable elements suggest that the OM destruction with 6% NaOCl solution (pH 8) does not attack the crystalline mineral phases. Hypochlorite solution leaves the Fe-oxides unaffected and slightly dissolves Al from poorly crystalline mineral phases. Loss of elements by NaOCl treatment can be mainly explained by organically-bound elements.
