The effect of different charges of sodium dithionite and bleaching times on the optical and mechanical properties and COD of bleached recycled mixed ONP and OMG pulps
Volume 29, Fall 3 , November 2014, , Pages 411-421
Abstract
This research was conducted to investigate the bleaching of combined old newspapers (ONP) and old magazines (OMG) deinked pulp using sodium dithionite. The pulp was bleached using 0.5, 0.75, and 1% sodium dithionite and different times of 30, 60 and 90 minutes. The pulps were then refined to 300 ml, ...
