In this study, purified cellulose was prepared from rice husk which is one of the major agricultural residues in Korea. The various bleaching processes such as ozone bleaching, ClO₂ bleaching and H₂O₂ bleaching were applied to remove residual lignin and impurities. In order to increase the contents of α-cellulose contents, the effects of acid and alkali treatments were evaluated. Although the multi stages of the bleaching processes resulted in less than 0.5 % residual lignin contents, the application of ozone leaded to the decrease in DP(degree in Polymerization) and α-cellulose contents. The alkali treatment after bleaching processes resulted in pure cellulose which showed more than 98% of α-cellulose contents.
