Investigation on TCF Bleaching of Tobacco stalk ( Nicotiana tabacum L.'Coker 347') Soda Pulp

In this study the effect of different values of peroxide in three levels 3%, 4%, 5% and sodium hydroxide in two levels 2%, 3%, on bleaching of tobacco stalks ( Nicotiana tabacum L. 'PVH 19') soda pulp was investigated. Tobacco stalks were soda pulped using 22% alkali in 170°C for 100 minut...
