摘要
分别利用微波辅助NaOH与传统水浴加热法提取柚皮纤维素,采用傅里叶变换红外光谱(FTIR)、热重分析(TGA)及扫描电镜(SEM)对柚皮纤维素的结构进行表征,分析探讨了在不同温度、NaOH质量分数、NaClO体积分数条件下纤维素得率。结果表明:微波提取纤维素最佳提取条件为NaOH质量分数6%、提取温度60℃、NaClO体积分数1%。在此条件下,柚皮纤维素表面光滑,有望成为一种良好的吸附材料。
The cellulose was extracted from pomelo peel by microwave assisted NaOH and traditional water bath heating method,respectively.The structure of the cellulose was characterized by Fourier tansform infrared spectroscopy(FTIR),thermogravimetric analysis(TGA) and scanning electron microscopy(SEM),and the yield of the cellulose was analyzed at different temperatures,mass fraction of NaOH and volume fraction of NaClO.The results showed that the optimal extraction conditions of cellulose by microwave were NaOH mass fraction 6 %,extraction temperature 60 ℃ and NaClO volume fraction 1 %.Under these conditions,the cellulose surface of pomelo peel was smooth,which was expected to become a good adsorption material.
