Investigation on the properties of totally chlorine free bleached soda - oxygen pulp from old corrugated container
Soda - oxygen pulping of old corrugated container to produce totally chlorine free bleached pulp was investigated. In order to reach the optimum delignification condition; four levels of sodium hydroxide (9, 11, 13, and 15 %), three cooking times (90, 120, and 150 minutes) and two cooking temperatur...
