Pretreatment of quinoa straw with 1-butyl-3-methylimidazolium chloride and physiochemical characterization of biomass

Quinoa straw was pretreated with 1-butyl-3-methylimidazolium chloride ([Bmim]Cl). The levels of pretreatment temperature, duration, and liquid/solid ratio were optimized using orthogonal design to enhance the reducing sugar yield of treated sample. Scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction were used to assess structural changes in native and pretreated biomass. The effect of [Bmim]Cl...
