Optimization of delignification process from red meranti wood sawdust pretreated with acidified sodium chlorite

Delignification is a process to remove the lignin content from lignocellulosic biomass to increase hydrolysis efficiency. In other word, the process ensure cellulose parts are more accessible. In the present research, there were two objectives; i) to optimize the operating parameters of acidified so...
