Abstract

Kenaf (Hibiscuc cannabinus L.) is a renewable resource for industry and kenaf lignin is syringyl-guaiacyl lignin. The electron beam irradiated on kenaf core various doses range from 200 to 1,000 kGy to improve delignification. The yield of lignin, which is 2.53 g from 10 g of electron beam irradiated kenaf core. A comparison extracted lignin between from native kenaf core and electron beam irradiated kenaf core was then studied through chemical structure and bonding property by a Fourier transform infrared spectroscopy (FT-IR). Thermal stability of the extracted-purified lignin was performed via differential scanning calorimetry (DSC). These results were explained that electron beam irradiation increased performance of extracting efficiency.
