We are currently conducting an experiment of extracting cellulose from sugarcane leaves. Can you help us for the best bleaching procedure? below is our bleaching procedure.
The bleaching treatment will be performed using 5% of sodium hypochlorite and 10% (v/v) acetic acid in a 1:1 ratio (total volume of 500). The alkali treated sugarcane leaves sample will be bleached to a solid-to-liquid ratio of 1:50 mL of bleaching agent solution. The bleaching process will be carried out at 70 °C for 1 hour .
Do we need to combine the 5% sodium hypochlorite and 10% glacial acetic acid, we assumed from the reference with a 1:1 ratio (total volume of 500 ml) is 250 ml of both chemicals 5% sodium hypochlorite and 10% glacial acetic acid will be mixed together with the samples and heated at 70 °C for 1 hour. We wanted to clarify regarding this methods we use since some studies use glacial acetic acid to adjust the ph.
Lastly, after bleaching the samples how to obtain cellulose powder? In our first try, We actually extracted white paste-like cellulose and after drying in an oven with a temperature of 60 °C for 1 hour it appear as a dry clay. What is the best to obtain cellulose fiber after bleaching?
Thank you! Your help is very much appreciated!
