Abstract:

Alkaline treatment is widely used for improving biogas production for lignocellulosic materials. This study was conducted to investigate the effect of alkaline treatment on physicochemical property of digested Spartina alterniflora (DSA). Fourier Transform Infrared Spectroscopy (FTIR), X-Ray diffraction patterns, proton Nuclear Magnetic Resonance Spectroscopy (1H-NMR), solid-state 13C-NMR Spectroscopy and some general indicators were used to analyze changes of the lignocellulosic structure and composition of NaOH-treated digested Spartina alterniflora. The results showed that, after NaOH treatment, surface lignin and some carbohydrate were destructed into lignin fragment, organic acids and some other small molecular organic matter, but the skeleton structure of lignin and cellulose of DSA were not destructed significantly. The crystalline of cellulose of DSA was transferred into biodegradable forms and content of crystalline of DSA and cellulose were increased after NaOH treatment. The results of 13C-NMR showed that methyl (CH3) and carboxylic C(COOH) groups of DSA were decomposed significantly.
