Description: Recently found experimental evidence has provided strong support for an alternative photoyellowing mechanism that suggests that pulp- photoyellowing occurs due to direct photooxidation of hydroquinones (present in mechanical pulps) top-quinones. Because hydroquinones were found to be present in pulps, it may be possible to quantify them. Quantification of mechanical-pulp hydroquinones is important because it would provide information on a pulp's potential for photoyellowing. One of the ways to accomplish this is to use the method that successfully detected hydroquinones, namely the method of "oxygensensitivity of laser- induced-fluorescence (LIF)". Preliminary findings of this work will be discussed in the presentation.
