摘 要:利用酸性亚氯酸钠和氢氧化钠溶液,脱除巴沙木中木质素和半纤维素,制得纤维素薄膜,研究该薄膜微观结构、元素分布与组成、浸润性等方面性能。结果表明,经化学法剥离后的纤维素吸附剂对染料亚甲基蓝的吸附容量可达120.0mg/g,与Langmuir和Temkin模型均能较好地符合。随着膜孔径的收缩和氧化石墨烯(GO)的负载,纤维素膜对抗生素的截留性能大大增强。在0.3MPa通液压力下,纤维素/GO膜的纯水通量提高至原通量的13.5倍[由56.5L/(m^(2)·h)到764.1L/(m^(2)·h)];纤维素/GO膜对环丙沙星的截留率可达65.6%(纤维素膜对环丙沙星截留率为50.9%)。The cellulose film was produced by using acidic sodium chlorite and sodium hydroxide solution to remove lignin and hemicellulose from balsa wood.The performance studies on microstructure,element distribution and composition,and wettability of this film were carried out,and the results showed that the adsorption capacity of the cellulose adsorbent after chemical stripping could reach 120.0mg/g for the dye methylene blue,which was in good agreement with both Langmuir and Temkin models.With the shrinkage of membrane pore size and the loading of graphene oxide(GO),the retention performance of the cellulose membrane for antibiotics was greatly enhanced.The pure water flux of the cellulose/GO membrane was increased to 13.5 times of the original flux[from 56.5L/(m^(2)·h)to 764.1L/(m^(2)·h)]at 0.3MPa flux pressure.The retention rate of ciprofloxacin by the cellulose/GO membrane was up to 65.6%(50.9%for ciprofloxacin by cellulose membrane).The related research work provided a new idea for the preparation and application of polysaccharide membranes.
