项目摘要

(1) The binding isotherms of nonionic surfactants onto water soluble polymer containing cyclodextrin (CD) were measured in aqueous solution. The nonionic surfactants used were polyoxyethylene nonylphenylether with different oxyethylene units. The binding affinities for nonionic surfactants decreased with increases in the length of oxyethylene units on the polymer. (2) Molecular mechanics (MM) and molecular dynamics (MD) simulations served to investigate the interaction of 2,3,7,8-tetrachlorodibenzodioxin(PCDD) and cycolodextrins (CD) in gas phase and water model. α-β-,γ-CD were used for the complex formation in this study. The more energetically stable complexes by inclusion with CD calculated based on MM were obtained compared with PCDD and CD alone, respectively. The structural information about the prefered complex formation by inclusion from the MD simulations was also obtained, and the relative stability of complex and the involved molecular interactions were determined. The results of the present MM and MD calculations were discussed, and compared with chemical structures and the relative stability of complexes. (3) The adsorption isotherms of phenol and onto bamboo charcoals and cyclodextrin beads were measured in aqueous solution. The bamboo charcoals used were different types of refinement degree prepared from different route temperature. In general, the adsorption affinities for phenol and bisphenol A increased with decreases in the refinement degree of bamboo charcoals. Phenol adsorbed about 10 times greater than bisphenol A. These results indicated that fine pores size of bamboo charcoals played an important role of the adsorption. The relationship between adsorption affinities and OSQR properties were also discussed in order to determine preferred adsorption behaviors of phenol and bisphenol A onto bamboo charcoals.
(1)在水溶液中测量了非离子表面活性剂在含有环糊精(CD)的水固体聚合物上的结合等温线。使用的非离子表面活性剂是具有不同氧乙烯单元的多氧乙二醇。非离子表面活性剂的结合亲和力随着聚合物上氧乙烯单元长度的增加而降低。 (2)分子力学(MM)和分子动力学(MD)模拟,用于研究2,3,7,8-四氯二苯甲二基二氧蛋白(PCDD)和环氧化胺(CD)在气相和水模型中的相互作用。在本研究中,使用α-β-,γ-CD进行复合形成。与单独的PCDD和CD相比,与基于MM计算的CD纳入CD的基本稳定复合物。还获得了通过包含MD模拟的首选复合物形成的结构信息,并确定了复合物的相对稳定性和所涉及的分子相互作用。讨论了当前MM和MD计算的结果,并将其与化学结构和复合物的相对稳定性进行了比较。 (3)在水溶液中测量了苯酚和竹木炭和环糊精珠的添加等温线。所使用的竹木炭是从不同路线温度制备的不同类型的精炼程度。通常,随着竹木炭的改进程度的降低,苯酚和双酚A的吸附亲和力增加。苯酚吸附的吸附物是双酚A的大约10倍。这些结果表明,竹木炭的细小孔尺寸起着吸附的重要作用。还讨论了吸附亲和力与OSQR特性之间的关系,以确定苯酚和双酚A在竹木炭上的首选增加行为。
