| Title |
Effect of pH on pulping and flotation of mixed office wastepaper |
| Date |
1999 |
| Description |
The effect of pulping reagents on the deinking 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 fibres as larger particles and a poor flotation response is obtained. 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 toner and mineral filler particles. On the basis of these flotation results and atomic force microscopy force experiments, it is known that the remarkable removal of mineral fillers and toner particles under acidic conditions is related to the heterocoagulation of toner and filler particles. |
