تحقیقات علوم چوب و کاغذ ایران, Vol 33, Iss 3, Pp 369-380 (2018)
The first act to ameliorate bleaching process is the major elimination of lignin. Actually, the use of oxygen delignification stage before bleaching process is the essential stage in improving bleaching process and reducing process emission. In this
