Given the increasingly stringent water quality standards and public concern over environmental issues, environmental engineers must aggressively pursue innovative, selective, and versatile treatment technologies for solving current pollution problems and preventing new ones. Carbon fibers (CFs) are, perhaps, the most innovative and successful carbon material developed within the past forty years. Although their applications in the control of environmental pollution are limited, today carbon fibers are used from sporting goods to aircraft structures. CFs pose an attractive alternative to traditional granular (GAC) and powdered (PAC) activated carbon treatment methods because their properties are superior to GACs and PACs. Research Objectives. The use of CFs in drinking water and industrial wastewater treatment applications offers exciting possibilities. Therefore, the primary goal of the research component of this CAREER proposal is to systematically investigate the efficacy of using carbon fibers for removing priority pollutants from aqueous solutions so that efficient treatment systems can be developed for use in environmental engineering applications. Specific objectives to address this goal are: 1) investigation of the mechanisms of adsorption of small-molecular weight organic chemicals and organic macromolecules by carbon fibers in aqueous phase, 2) investigation of the mechanisms of competitive adsorption, including preloading effects, on carbon fibers, and 3) assessment of the feasibility and efficacy of carbon fibers for use in environmental treatment systems.Teaching Objectives. The primary educational goal of this proposal is to develop computer animations for teaching fundamentals of physicochemical processes to undergraduate and graduate students. Several such products have already been developed for basic science courses, however there is practically no material for environmental engineering education. Relatively well-known principles of physicochemical processes are one of the most suitable areas to describe and demonstrate using computer animations and visual-aids. In addition, graduate level curses on water treatment design and on surfaces and interfaces in the aquatic environments will be developed to meet the needs in the Department of Environmental Engineering and Science at Clemson University. The research findings will be employed in these courses and they will be incorporated directly into the PI's educational activities.

鉴于日益严格的水质标准和公众对环境问题的关注，环境工程师必须积极追求创新，选择性和通用的处理技术，以解决当前的污染问题并防止新的污染。碳纤维（CF）可能是过去40年来开发的最具创新性和最成功的碳材料。尽管碳纤维在控制环境污染方面的应用有限，但如今碳纤维的应用范围从体育用品到飞机结构。CF是传统颗粒（GAC）和粉末（PAC）活性炭处理方法的一种有吸引力的替代方法，因为它们的性能上级GAC和PAC。研究目的。在饮用水和工业废水处理应用中使用CF提供了令人兴奋的可能性。因此，本CAREER提案的研究部分的主要目标是系统地研究使用碳纤维从水溶液中去除优先污染物的功效，以便开发有效的处理系统用于环境工程应用。本课程的具体目的是：1）研究碳纤维在水相中吸附小分子量有机物和有机大分子的机理; 2）研究碳纤维的竞争吸附机理，包括预负载效应; 3）评估碳纤维用于环境处理系统的可行性和有效性。教学目的本计画的主要教育目标是发展电脑动画，以教授本科生与研究生物理化学过程的基础知识。已经为基础科学课程开发了几种这样的产品，但实际上没有环境工程教育的材料。物理化学过程的相对熟知的原理是使用计算机动画和视觉辅助来描述和演示的最合适的领域之一。此外，研究生水平的诅咒水处理设计和表面和界面的水生环境将开发，以满足在克莱姆森大学环境工程与科学系的需求。研究结果将用于这些课程，并将直接纳入PI的教育活动。
