Enhance the surface functionality of sugarcane bagasse and rice husk-based magnetic nanoparticle biocomposites by amine group

Abstract

A natural fiber is potential material to use for wide range applications. Due to high content of cellulose, it is also abundant in nature. The combination of two fiber form sugarcane bagasse (SB) and rice husk (RH) could be used as template for magnetic nanoparticle biocomposites. In order to produce high functionality of biocomposites, it is important to modify by amine group. This research is focus on evaluate and characterized the concentration of amine precursor on synthesis of biocomposites. The delignified of both RH and SB were mixed in ethylene glycol, iron trichloride, sodium acetate anhydrous, and 1.6-hexanediamine. The solution was poured into Teflon Stainless Steel Autoclave then heated at 200 oC for 6 h. Amine source concentration was evaluated by different concentration of 1.6-hexanediamine. The 7 mL of 1.6-hexanediamine was achieved as optimum concentration with contain of 2.64 mmol/g. The Fe contain on biocomposites was 97.97% that proved by XRF analysis and has specific peaks at 36o, 43o, and 57o by X-Ray Diffraction (XRD). The peaks at 1640 cm−1 and 582 cm−1 are identified for N–H bending vibration and Fe-O on biocomposites, respectively. The iron content, amine group, and structure of of biocomposites could be good candidate for wide range applications.
