DESCRIPTION (provided by applicant): More than 100,000 synthetic chemicals are used in a variety of domestic, industrial, and agricultural applications, resulting in contamination of precious water with many harmful toxins. Various toxic organic chemicals among those have a potential to cause a number of serious health hazards, including cancer, other internal organ disorders, developmental and reproductive disorders, and dysfunction with a serious health threat. One of the primary sources of exposure to those toxic organic chemicals is drinking water. There are also a number of methods which have been developed to attempt to remove various health hazardous organics. However, there is no device which is able to remove a wide spectrum of organic chemicals using one unique purification module, or a simple combination of modules. We will attempt to develop an innovative sorbent system composed of specifically functionalized, robust and light-weight smart fibers. These will efficiently and economically remove a wide spectrum of organic pollutants from contaminated drinking water. This novel/smart device will be easily adaptable to POU/POE, as well as large water treatment facilities in a cost effective manner. The goals for this Phase I program will be achieved through the following Specific Aims: (1) Functionalize ACFs Which Have Stabilized Micro/Nano Matrices. (2) Study the Adsorption Characteristics of Prepared ACFs Using Concerning Toxic Organic Chemical Pollutants. (3) Evaluate and Devise the ACFs for Removal of a Wide Spectrum of Organic Chemicals. The evaluation includes performance efficacies in terms of both technology and economics. If this Phase I program is successful, a Phase II proposal will be submitted for the construction and testing of a prototype filter module for application studies using drinking water and ground water directly. PUBLIC HEALTH RELEVANCE: The pollution of ground and drinking water by organic chemicals has attracted increasing global attention in recent decades as a critical environmental menace and a serious health threat worldwide. The industrial effluent from chemical manufacturing and decomposed or leached chemicals from plastic products are both significant sources of organic chemical contamination. Our smart adsorption system satisfies the unmet need in the clean-up of hazardous organic chemicals from drinking water sources in a cost effective manner with high application versatility.

描述（由申请人提供）：超过 100,000 种合成化学品用于各种家庭、工业和农业应用，导致珍贵的水受到许多有害毒素的污染。其中各种有毒有机化学物质有可能造成许多严重的健康危害，包括癌症、其他内脏器官疾病、发育和生殖障碍以及严重威胁健康的功能障碍。接触这些有毒有机化学物质的主要来源之一是饮用水。还开发了许多方法来尝试去除各种对健康有害的有机物。然而，没有一种设备能够使用一种独特的纯化模块或简单的模块组合来去除多种有机化学物质。我们将尝试开发一种由特殊功能化、坚固且轻质的智能纤维组成的创新吸附剂系统。这些将有效且经济地从受污染的饮用水中去除多种有机污染物。这种新颖/智能的设备将能够以经济有效的方式轻松适应 POU/POE 以及大型水处理设施。该第一阶段计划的目标将通过以下具体目标来实现：（1）功能化具有稳定微/纳米基质的ACF。 (2)研究制备的ACF对有毒有机化学污染物的吸附特性。 (3) 评估和设计用于去除多种有机化学品的 ACF。评估包括技术和经济方面的绩效效率。如果第一阶段计划成功，将提交第二阶段提案，用于建造和测试原型过滤器模块，以直接使用饮用水和地下水进行应用研究。 公共健康相关性：近几十年来，有机化学品对地下水和饮用水的污染作为一种严重的环境威胁和严重的健康威胁，已引起全球越来越多的关注。化学品制造的工业废水和塑料产品分解或浸出的化学物质都是有机化学污染的重要来源。我们的智能吸附系统以经济有效的方式满足了饮用水源中危险有机化学品净化的未满足需求，具有较高的应用多功能性。
