Miller, Jan D. | Interaction forces between ink particles, cellulose fibers and mineral fillers as determined by AFM | Recycling of wastepaper is an important industrial activity for the conservation of our natural resources. Wastepaper is mostly generated from newspaper and office waste (from photocopiers and laser printers) [1]. One important step in wastepaper recycling is the separation of ink from cellulose... | Solution; Wastepaper; Chemistry | 1996 |
