摘要

从秀丽线虫中分离得到了一种可生物降解的天然多糖——壳聚糖，并利用傅里叶红外光谱(FTIR)和MALDI TOF对其进行了表征。去乙酰化程度(DAC)为85%。将壳聚糖与三聚磷酸钠(sTPP)交联制备了壳聚糖纳米颗粒，并用FTIR和FESEM对其进行了表征。观察到纳米颗粒的尺寸为30nm-100nm。Langmuir等温线分析证实壳聚糖纳米颗粒能够吸附50-80%的- Remazol Brilliant Blue。

Adsorption efficacy of chitosan nanoparticles from Cunnighamella elegans on RBB dye

Chitosan, a biodegradable natural polysaccharide derived from Cunninghamella elegans was isolated, characterized using Fourier transform infrared spectroscopy (FTIR) and MALDI TOF. The degree of deacetylation(DAC) was found to be 85%. Chitosan nanoparticles were prepared by cross-linking chitosan with sodium tripolyphosphate (sTPP), The nanoparticles were again characterized by FTIR and FESEM. The size of the nanoparticle was observed to be 30nm–100nm. Langmuir Isotherm analysis confirms that chitosan nanoparticles were able to adsorb 50–80% of - Remazol Brilliant Blue.
