摘要
从车前草皮中分离纤维素，用三氯乙酸进行羧甲基化，得到0.9936 g羧甲基纤维素。羧基甲基三纤维素在3448.72 cm-1波长处存在-OH振动。此外，1026.13 cm-1区域的波数归属于醚振动(- o -)和羧基振动(1651.07 cm-1)。SEM形貌分析结果也显示出更光滑、均匀的孔隙和更大的表面积。采用原子吸附分光光度计(AAS)分析了其对浓度为100ppm的Cu2+离子的吸附能力。结果表明，搅拌时间为90 min时，羧甲基三纤维素和纤维素的最佳吸附率分别为97.266%和21.602%。
Synthesis of Carboxymethyltricellulose and Its Adsorption Towards Cu2+ Ions
Cellulose was isolated from plantain skin and then carboxymethylated with trichloroacetic acid which resulted a 0.9936 gram of carboxymethylcellulose. The FT-IR spectroscopy analysis of carboxymethyltricellulose indicated the –OH vibration at wavelength of 3448.72 cm-1.Moreover, a wavenumber in the region of 1026.13 cm-1 is attributed to ether vibration (-O-) and carboxyl vibration at 1651.07 cm-1. The results of morphological analysis using SEM also showed a smoother, homogeneous pore, and a larger surface area. The adsorption capability for Cu2+ ions at concentration of 100 ppm was analyzed by atomic adsorption spectrophotometer (AAS). It shows that the optimum adsorption was found to be at a 90 minutes agitation process for both carboxymethyltricellulose and cellulose with about 97.266% and 21.602% respectively.
