Chlorine Dioxide Bleaching of Soda-anthraquinone Jute Pulp to a Very High Brightness

  title={Chlorine Dioxide Bleaching of Soda-anthraquinone Jute Pulp to a Very High Brightness},
  author={Md Sarwar Jahan and Yonghao Ni and Zhibin He},
Bleaching of soda-anthraquinone jute pulp by chlorine dioxide (ClO2) was studied to reach a target brightness of above 88% for the purpose of using less bleaching chemicals. The performance of either chlorine dioxide or peroxide in the final bleaching to boost brightness was also studied. The experimental results revealed that the final brightness depended on ClO2 charge in the Do and D1 stages. The brightness reversion was lower when the final stage brightening was done by peroxide. The use of… CONTINUE READING
