Abstract: In this paper,the effect of modes introducing Mg(OH)₂ on hydrogen peroxide(H₂O₂)bleaching processes was investigated for the eucalyptus kraft pulps.There are three ways to introduce Mg(OH)₂ into the bleaching system,i.e.,the direct-addition,or fresh-formed Mg(OH)₂ by adding magnesium sulfate into a pulp slurry pre-mixed with sodium hydroxide,or vice verse.The results showed that the particle size distributions of Mg(OH)₂ were quite different for the three cases.The average particle sizes are much smaller for fresh-formed Mg(OH)₂ than for direct-addition.As a consequence,the processes with fresh-formed Mg(OH)₂ were proved more effective for the pulp bleaching,and there were more hydrogen peroxide found in the bleaching effluents and the favorable pulp qualities.The time-dependent pH profiles of the process effluents also indicated that the decomposition of H₂O₂ for direct-addition or for no addition of Mg(OH)₂ was very significant,especially during the early stage of the bleaching processes.
