Kinetics of alkaline delignification of hemp and determination of lignin content by thermogravimetry

Raw hemp (Cannabis sativa L.) was subjected to alkaline delignification with the application of NaOH ranging from [0.125M] to [1M] for times from 5 to 480¿min. Lignin contents of the original and delignified samples were determined. The samples were subjected to thermogravimetric analysis (TGA) unde...
