Title

INVESTIGATION ON TCF BLEACHING OF TOBACCO STALK (NICOTIANA TABACUM L.’ COKER 347’) SODA PULP

Pages

  619-628

Abstract

 In this study, the effect of three levels (3%, 4%, 5%) of hydrogen peroxide and two levels (2%, 3%) of sodium hydroxide on BLEACHING of TOBACCO STALKs (Nicotiana tabacum L. ’PVH 19’) SODA PULP was investigated. TOBACCO STALKs were pulped using 22% alkali at 170oC for 100 minutes. The produced pulp showed 37.1% YIELD and KAPPA NUMBER of 62. BLEACHING process included two stages: CHELATING and alkali peroxide BLEACHING. Results indicated that both BRIGHTNESS and KAPPA NUMBER decreased by increasing sodium hydroxide and hydrogen peroxide level. The results of 3% caustic soda and 5% hydrogen peroxide treatment without CHELATING stage indicated that initial CHELATING stage significantly affected the BRIGHTNESS, KAPPA NUMBER and YIELD of the bleached pulp, and this treatment showed the lowest BRIGHTNESS and the highest KAPPA NUMBER and YIELD among all treatments. Finally, 3% caustic soda and 5% hydrogen peroxide treatment with initial CHELATING stage had the highest BRIGHTNESS (44.50%) and the lowest YIELD (83.20%) was selected as the best treatment.
