Fiber adsorbent for remediation of multisolute contamination in drinking water.

项目摘要 这个SBIR项目开发的水处理产品将让更多的人 有机会过更健康的生活，并将通过增加可获得性来加强社区 饮用水资源。饮用水污染是一个古老的问题，它已经 近几十年来，由于人为毒素(药物、增塑剂、 杀虫剂、消毒剂副产品等)通过废水进入饮用水水库， 农业径流、暴雨水以及受污染的空气和土壤。通过以下途径暴露于这些毒素 饮用水正在导致慢性、复杂的疾病；其负担主要落在 社会经济上处于不利地位的社区。去除这些有毒化合物是 保护健康势在必行。 传统的吸附技术相对简单，成本效益高，但不能 具有复杂的结构，以允许同时移除广泛的 有毒的有机化学品。其他净化技术(即反渗透膜和 羟基自由基)未能为居民区提供一种简单且经济有效的手段 去除饮用水供应中现在发现的许多不同的有机化学物质。是什么 在价值30亿美元的美国住宅治疗市场中，缺少一个简单且经济实惠的POU 可同时去除有毒有机和无机污染物的产品。 通过这个SBIR项目，Chemica的目标是为水领域带来一个及时的新工具 处理/净化，专门针对易于使用的难以去除的污染物 和实惠的方式。这将通过应用Chemica的专有表面来实现 对坚固的碳纤维基材的改性技术。Chemica的新型纤维很容易 可扩展，可定制以满足用户的特定需求。通过之前的努力，化学 已经开发出了针对有机毒素或无机毒素的吸附剂。这件事的目标是 SBIR计划是开发一种能够同时吸附这两种有机物质的吸附剂 和无机毒素的高效机制，这将通过 具体目标如下：1.离子液体辅助制备功能化纤维； 2.ACFS对有毒有机物和无机物的去除特性 关键词：饮用水，新兴污染物，毒性，吸附剂，碳纤维 药品、增塑剂、农药、消毒副产品、重金属、铅、 配位化学、有机化学、挥发性有机化合物、砷、修复、离子液体

Project Summary The water treatment product developed in this SBIR program will give more people the opportunity to live healthier lives and will strengthen communities by increasing available potable water resources. The contamination of drinking water is an age-old problem which has been made worse in recent decades by man-made toxins (pharmaceuticals, plasticizers, pesticides, disinfectant by-products, etc.) entering drinking water reservoirs via wastewater, agricultural runoff, storm water, and polluted air and soil. Exposure to these toxins through drinking water is leading to chronic, complex diseases; the burden of which falls primarily on socioeconomically disadvantaged communities. Removal of these toxic compounds is imperative to protect health. Traditional adsorption technologies which are relatively straightforward and cost-effective do not have the structural sophistication to allow for the simultaneous removal of a broad spectrum of toxic organic chemicals. Other purification technologies (i.e. reverse osmosis membranes and hydroxyl radicals) have failed to provide a simple and cost-effective means for residential areas to remove the many different organic chemicals now found in drinking water supplies. What is missing from the $3B US residential treatment market is a simple and cost effective POU product for the simultaneous removal of toxic organic and inorganic contaminants. Through this SBIR project, Chemica aims to bring a timely new tool to the field of water treatment/purification that specifically targets difficult to remove contaminants in an easy-to-use and affordable manner. This will be achieved through applying Chemica’s proprietary surface modification techniques to a robust carbon fiber substrate. Chemica’s novel fiber is easily scalable and can be tailored to meet users’ specific needs. Through previous efforts Chemica has developed adsorbents to target either organic toxins or inorganic toxins. The goal for this SBIR program is to develop an adsorbent capable of simultaneous adsorption of BOTH organic and inorganic toxins in a highly efficient mechanism, which will be achieved through the following Specific Aims: 1. Ionic Liquid Assisted Preparation of Functionalized Fiber; 2. Characterization of Toxic Organic and Inorganic Chemical Removal by ACFs.
