项目摘要

(1)The adsorption isotherms of surfactants onto bamboo charcoals 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 the both surfactants increased with decreases in the refinement degree of bamboo charcoals. The results indicated that fine pores over size of bamboo charcoals played an important role of the adsorption. The relationship between adsorption affinities and chemical properties were also discussed in order to determine preferred adsorption behaviors of surfactants onto bamboo charcoals.(2) The adsorption isotherms of phenol and bisphenol A onto adosorbents were measured in aqueous solution. The adsorbents used were bamboo charcoal, activated carbon, and cyclodextrin polymer beads. Molecular modeling studies were also performed by means of Monte Carlo simulation on molecular mechanics (MM)to determine the preferred complex formation of phenol and bisphenol A by cyclodextrins.(3) The rejection of environmental inhibitor was measured by using the natural woody coals such as the bamboo charcoal, pumpkins, and pinecones in aqueous solution. Any adsorbate had comparatively adsorbed the pinecone that the specific surface area was as large as bamboo charcoal. The molecular size of adsorbents influenced the adsorption.(4) The study of the adsorption ability by using the complex that coated the cyclodextrin to the bamboo charcoals. The result in which obtaining the tendency that part was excluded by coating the cyclodextrin in the mousou bamboo and the rejection rises, and providing and decreasing in long-jointed bamboo charcoal. The results suggested that the molecular size influenced the adsorptivity of the reforming bamboo charcoal.

(1)测定了水溶液中表面活性剂在竹炭上的吸附等温线。所用竹炭在不同的工艺温度下制备出不同的细化程度。总体而言，随着竹炭细化程度的降低，两种表面活性剂的吸附亲和度均增大。结果表明，竹炭的细孔在吸附过程中起重要作用。为了确定表面活性剂在竹炭上的优先吸附行为，还讨论了表面活性剂的吸附亲和度与化学性质之间的关系。(2)测定了苯酚和双酚A在吸附剂上的吸附等温线。所采用的吸附剂为竹炭、活性炭和环糊精聚合物珠。通过分子力学蒙特卡罗模拟（MM）进行了分子模型研究，确定了环糊精对苯酚和双酚A络合物的首选形成形式。(3)采用竹炭、南瓜、松果等天然木本煤水溶液对环境抑制剂的去除率进行了测定。任何一种吸附物对松果的吸附效果都比较好，比表面积与竹炭相当。吸附剂的分子大小对吸附有影响。(4)利用包覆环糊精的配合物对竹炭的吸附性能进行了研究。结果表明，采用环糊精包覆在鼠头竹中，得到了部分被排除的趋势，而在长节竹炭中得到了提供和减少的趋势。结果表明，分子大小对重整竹炭的吸附性能有影响。
