Effect of hot acid hydrolysis and hot chlorine dioxide stage on bleaching effluent biodegradability The hot acid hydrolysis followed by chlorine dioxide (A/D~*) and hot chlorine dioxide (D~*) technologies have proven very useful for bleaching of eucalyptu... CM Gomes,JL Colodette,NRN Del...
By avoiding oxygen delignification stage, pulp was bleached directly by using DEDsequence of elementary chlorine free bleaching. The average brightness and viscosity after final stage were 79.9 per cent ISO and 614 mL/g, respectively. Improvement in brightness was remarkable, but the viscosity ...
The effect of different variations for the combined use of ClO2 [10049-04-4] and Cl solns. during the bleaching of sulfite and sulfate pulps on the stiffness, d.p., whiteness, and mech. strength was studied. The use of a mixt. of ClO2 and Cl and also the consecutive use of each ...
