Concerns on Analytical Results Involving Infrared to Microscopic Data Dealing with Ionic Liquids in Pretreatment of Lignocellulosic Biomass

Abstract:

Lignocellulosic biomass containing cellulose, hemicelluloses and lignin is significantly analyzed via methods from infrared to microscopy. These methods help researchers to explore the organic or inorganic functional groups and physical surface impacts microscopically on the particles of the pretreated biomass. Some concerns arise in understanding the data results. An investigation with the presence of ionic liquids on Leucaena Leucocephala (Petai Belalang), Acacia Auriculiformis and Melastoma Malabathricum (Senduduk) are reported via the results of Fourier Transform Infrared Spectrum (FTIR) and Scanning Electron Microscopy (SEM). The model ionic liquids as green solvents used are 1-Ethyl-3-methylimidazolium Acetate (EMIMAc) and 1-Ethyl-3-methylimidazolium Chloride (EMIMCl). This work is very essential to sustain preliminary reliable understanding on the chemical and physical effects on lignocellulosic biomass during pretreatment with solvents.
