Abstract

This study was made to determine a method that would deink xerographic wastepaper effectively. The study was done in two parts, the first being a preliminary feasibility study of the deinking methods found in a literature search. The second part involved a further study of the temperature variable of the most feasible method found in the first part. The results indicated that the flotation method would deink xerographic wastepaper very effectively. Temperatures between 130oF and 190oF were used during the pretreatment stage of the flotation method but no significant change was found in deinkability.
