Olive pomace (OP) was used as raw material to extract cellulose by multi-step chemical method, and the extracted characterized. The two steps of alkali treatment (alkali concentration, reaction time temperature) bleaching (H2O2 NaOH were optimized. results showed that optimum conditions for follows: concentration 6%, 2 h, temperature 95 °C; optimal 7.5% H2O2 solution, 5% NaOH, 75 °C. After trea...
