Studing the effect of reducing agents (sodium borhydrade and sodium dithionite) on chemical structures of poplar kraft and bagasse soda alkali lignin by FT-IR spectroscopy
In this study, the chemical changes of functional groups (C=O) and double bond (C=C), induced in the structures of poplar kraft lignin and bagasse soda lignin were investigated. The reducing effect of sodium borohydride and sodium hydrosulfite, followed by the UV irradiation on these two compounds w...
