<p>Methods for depolymerizing polysaccharides are disclosed. In certain exemplary methods, polysaccharides having a first average molecular weight can be reacted with hydroxyl free radicals to produce polysaccharides having a second average molecular weight lower than the first average molecular weight. The hydroxyl free radicals can be formed by interaction of an oxidant with a catalyst comprising a polydentate ligand complexed with a metal ion. In certain exemplary embodiments, the oxidant can be hydrogen peroxide, and the catalyst can be iron methylglycine diacetate or iron-2,3,4,5,6 pentahydroxyhexanoate.</p> |
