Article Effect of Sodium Hydroxide Pretreatment on Rice Straw Composition

Pratiksha Shrestha

sodium hydroxide helps to remove lignin and hemicellulose from lignocellulosic material. The suitable concentration of NaOH can be 17.5% w/v and the alkali to substrate ratio loading may depend on intended result. hope this helps.

Vitalijs Radenkovs

Dear Jerson!

It’s not clear what type of fibre you’re talking about since rice straw itself is fibre.

Using sodium hydroxide you could do full or partial hydrolysis of your lignocellulosic material. The ration of hydrolysis depends on the concentration of NaOH, time and conditions.

It would be great if you could clarify the exact compounds you want to extract.
