Description
In the present investigation, extraction of holocellulose from bagassae has been performed. NaOH, Na/sub 2/SO/sub 3/ and combination of NaOH and Na/sub 2/SO/sub 3/ were three delignifying agents being used. Different experimental conditions including cooking time, cooking temperature and concentration of delignifying agent were observed. Bagasse was initially washed, dried, grinded and screened to 80 mesh. Then its cooking was carried out. The liquid to solid ratio was 5:1. The washed and dried product was then tested to find the Kappa No. according to the Technical Association for Pulp and Paper Industry (TAPPI) T-236 method. Combination of NaOH and Na/sub 2/SO/sub 3/ rendered the best result at 140 degree C, 5 hr and 30/70 mixture composition. X-Ray Fluorescence Spectrometry (XRF) and Scanning Electron Microscopy (SEM) results also confirmed the breakage of lignin. (author)
