| Abstract: | SUMMARIES. Alcaline solutions: have many uses in paper conservation: to change and/or buffer the pH of other solutions; to wash paper in order to enhance removal of soluble acids and dégradation products (usually following a neutral pH water wash); and to deposit an alkaline reserve in paper. Alkaline solutions can be divided into aqueous and non-aqueous types. The most common aqueous solutions used in paper conservation are calcium hydroxide, magnesium bicarbonate, and ammonium hydroxide: The most common nonaqueous alkaline reserve systems are Wei T´oTM and Bookkeeper. |
