Abstract
The use of zeta potential as a parameter in the washing stages of newsprint deinking is discussed. Previous research provided the temperature, time, and consistencies used in the hydropulper and washing stages. The research carried out tried to determine whether or not zeta potential can be used as a way of increasing the effectiveness of the washing stages. The research carried out tried to determine whether or not zeta potential can be used as a way of increasing the effectiveness of the washing stages. By varying the zeta potential with chemical additives it was found that very little correlation could be seen between the zeta potential and the brightness resulting from the flotation cell and sidehill screen washings.
It was also determined that the microelectrophoresis method of measuring zeta potential has no validity when used to measure fiber charge if the fines in the system do not have the same charge as the fibers.
