    Patent number: 8540848
    Abstract: For decades books and other paper documents have been deteriorating in archives and libraries around the world because the acidity of the paper is increasing so much (wherein the pH decreases) that the paper cellulose is decomposing so that the paper loses its cohesion and thereby degenerates in terms of quality. The invention relates to an improved method for de-acidifying paper. The invention also relates to a device for applying such a method.
