| Title |
Surface chemistry of pulping and flotation for mixed office wastepaper |
| Date |
1997 |
| Description |
The effect of pulping reagents on the de-inking flotation of laser printed wastepaper was investigated with regard to the removal efficiency of toner and mineral filler particles at different pH values. These results show that caustic pulping causes the toner to be released from the fibers as larger particles with a reduced hydrophobicity. On the other hand, neutral pulping not only causes the toner to be released as smaller particles but also increases the simultaneous flotation removal of mineral filler particles. |
