Cellobiose, a dimer of glucose wearing a glycosidic bond as in cellulose, was used as model molecule to understand the chemical degradation pathways taking place in iron gall inks impregnated papers. Experiments were carried out in liquid phase at 80 °C to study the effects of pH and of the presence of iron and oxygen on the cleavage of the glycosidic bond. Capillary electrophoresis was used to quantitatively...
Iron gall inks (IGI) were largely used for writing until the nineteenth century. Under certain circumstances, they provoke a substantial degradation of their cellulosic support. It was shown in a previous works that combination of oxygen and iron largely impacts cellulose chain breaking occurring in acidic conditions (pH 3–4). The present study aims to study the kinetic of this degradation. It assesses...
