This research work describes the production of pure cellulose from hardwood kraft pulp by an environmental friendly process. To achieve this goal two main strategies are approached: (i) pulp deilgnification and (ii) pulp purification. For pulp delignification hydrogen peroxide is chosen with copper phenanthroline complex. Initially oxidation efficiency of copper phenanthroline with hydrogen peroxide is studied with lignin model compound, i.e., veratryl alcohol. Then its delignification effect is studied with oxygen delignified kraft pulp. After delignification pulp is purified by cold caustic extraction and ozone treatment. With this approach pure cellulose is produced, whose chemical properties are similar the different grades of pure celluloses available. By this process a wide rang of pure celluloses can be produced for different products.
