What exactly happens during alkali pretreatment (using NaOH or Ca(OH)2) and bleaching (with H2O2) of lignocellulosic biomass (agricultural residue)?

04 August 2022 0 4K Report

Does the alkali pretreatment followed by bleaching of biomass involve a certain chemical reaction or is it a physical process such as extraction? I want to know the exact mechanism of these processes and the parameters affecting the process yield.
