Smart adsorption system for removal of toxic, organic chemicals from drinking wat

超过100，000种合成化学品用于各种家庭，工业和农业应用，导致宝贵的水被许多有害毒素污染。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、其他内脏器官疾病、发育和生殖障碍以及功能障碍，对健康构成严重威胁。接触这些有毒有机化学品的主要来源之一是饮用水。也有许多方法已被开发出来，试图去除各种健康有害的有机物。然而，没有能够使用一个独特的净化模块或模块的简单组合来去除宽范围的有机化学品的装置。我们将尝试开发一种创新的吸附剂系统组成的专门功能化的，强大的和重量轻的智能纤维。这些将有效和经济地从受污染的饮用水中去除广泛的有机污染物。这种新颖/智能的设备将很容易适应POU/POE，以及以成本效益的方式大型水处理设施。第一阶段计划的目标将通过以下具体目标实现：（1）功能化具有稳定的微/纳米基质的ACF。(2)活性炭纤维对有毒有机污染物的吸附性能研究。(3)活性炭纤维去除多种有机物的评价与设计。评价包括技术和经济两方面的绩效。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，用于直接使用饮用水和地下水的应用研究。 公共卫生相关性：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全球范围内的严重健康威胁引起了越来越多的全球关注。化学品生产的工业废水和塑料制品分解或沥滤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具有高应用通用性的成本效益方式满足了从饮用水源中清除有害有机化学品的未满足需求。

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.
