The effect of sodium and calcium ions in the deacidification of paper : a chemo-physical study using thermal analysis
Título: The effect of sodium and calcium ions in the deacidification of paper : a chemo-physical study using thermal analysis / by Lorena Botti... [et al.]
Notas: Resumen: Due to the key role played by acidity in the degradation of paper objects, its neutralization is one of the processes most frequently in conservation. The most common deacidifying agents in aqueous solution are calcium bicarbonate, calcium hydroxide and borax (sodium tetraborate). The purpose of the study reported here was to compare the effects of sodium and of calcium ions on paper. As a result, the theory presented is that it is not the sodium ions which have a negative effect, but the salt formed with tetraborate ions.
