Abstract

This study assesses the potential of UV light as method to bleach eucalyptus pulps in different steps of their chemical bleaching process in a pulp mill. Higher brightness increasing were obtained on dirtier pulps, that is, alkaline washed and oxygen delignified pulps. In any case, photobleaching shows first-order kinetics. Rate of chromophores removal is proportional to the chromophores content in fiber surface. Complementarily, thermogravimetric analysis proved that UV light (400 nm wavelength) do not damages fiber integrity
