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(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，导致宝贵的水受到许多有害毒素的污染。其中各种有毒有机化学品有可能造成一些严重的健康危害，包括癌症、其他内脏疾病、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品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个独特的净化模块或简单的模块组合来去除广泛的有机化学物质。我们将尝试开发一种创新的吸附系统，由专门功能化、坚固和轻质的智能纤维组成。这些措施将有效和经济地从受污染的饮用水中去除多种有机污染物。这种新型/智能设备将以经济高效的方式轻松适应POU/POE以及大型水处理设施。这一第一阶段计划的目标将通过以下具体目标来实现：(1)使具有稳定微/纳米基质的ACF功能化。(2)研究了制备的ACF对有毒有机污染物的吸附特性。(3)评估和设计ACFS用于去除广谱有机化学品。该评价包括技术和经济两方面的绩效效益。如果这一第一阶段方案成功，将提交第二阶段提案，以建造和测试直接使用饮用水和地下水进行应用研究的原型过滤器模块。 与公共健康相关：近几十年来，有机化学品对地面和饮用水的污染日益引起全球的关注，成为一个严重的环境威胁和世界范围内的严重健康威胁。化工生产产生的工业废水和塑料制品分解或浸出的化学品都是有机化学品污染的重要来源。我们的智能吸附系统以高性价比和高度的应用通用性，满足了饮用水水源中危险有机化学品清理方面尚未得到满足的需求。
