Molybdo-vanado-phosphate heteropolyanion catalyzed pulp ozonation in acetone/water solution. Part 1. Effect of process variables.


The effect of solvent and catalyst concentration, pH and ionic strength on ozone bleaching of commercial eucalyptus kraft pulp in acetone-water solution in the presence of Keggin-type heteropolyanion [PMo(7)V(5)O(40)](8-) (HPA-5) has been examined and compared with conventional (solvent/catalyst free) ozonation systems. The solvent content and medium… (More)
