摘要

多孔配位聚合物(pcp)是一种具有较大比表面积和孔容的多孔材料，有望作为环境污染物的分离材料。本研究的目的是评估一种PCP MIL-53(Al)在土臭素和2-MIB分离中的适用性。MIL-53(Al)对亚甲基蓝和碘的吸附性能低于活性炭。MIL-53(Al)对霉味剂的吸附时间比活性炭长，最终吸附量比活性炭低。制备了各种吸附剂对霉味剂的吸附等温线，并对其吸附性能进行了评价。与活性炭相比，MIL-53(Al)在纯水中的吸附量极低。另一方面，MIL-53(Al)对供水原水中气味剂的吸附量并不比活性炭低多少。该研究表明，具有均匀孔径的吸附剂，如MIL-53(Al)，不易受到其他共存物质的干扰。这一发现可能对今后发展霉味剂吸附剂具有重要意义。

Adsorption of Geosmin and 2-MIB to Porous Coordination Polymer MIL-53(Al)

Porous coordination polymers (PCPs) are porous materials with large specific surface area and pore ume, and are expected to be used as separation materials for environmental pollutants. The aim of this study was to evaluate the applicability of MIL-53(Al), a type of PCP, for the separation of geosmin and 2-MIB. The adsorption performance of MIL-53(Al) for methylene blue and iodine was determined to be lower than that of activated carbon. The time required for the adsorption of musty odorants by MIL-53(Al) was longer than that by activated carbon, and the final adsorption amount was lower than that by activated carbon. Furthermore, adsorption isotherms for the adsorption of musty odorants by each adsorbent were prepared and their adsorption performance was evaluated. The amount of odorant adsorbed by MIL-53(Al) in pure water was extremely low compared to that of activated carbon. On the other hand, the amount of odorants adsorbed by MIL-53(Al) in raw water for water supply was not much lower than that of activated carbon. This study suggests that adsorbents with uniform pore size, such as MIL-53(Al), are less susceptible to interference by other coexisting substances. This finding may be important for future development of adsorbents for musty odorants.

期刊介绍： The Journal of Water and Environment Technology is an Open Access, fully peer-reviewed international journal for all aspects of the science, technology and management of water and the environment. The journal’s articles are clearly placed in a broader context to be relevant and interesting to our global audience of researchers, engineers, water technologists, and policy makers. JWET is the official journal of the Japan Society on Water Environment (JSWE) published in English, and welcomes submissions that take basic, applied or modeling approaches to the interesting issues facing the field. Topics can include, but are not limited to: water environment, soil and groundwater, drinking water, biological treatment, physicochemical treatment, sludge and solid waste, toxicity, public health and risk assessment, test and analytical methods, environmental education and other issues. JWET also welcomes seminal studies that help lay the foundations for future research in the field. JWET is committed to an ethical, fair and rapid peer-review process. It is published six times per year. It has two article types: Original Articles and Review Articles.
