Fiber adsorbent for remediation of multisolute contamination in drinking water.

项目摘要 SBIR项目开发的水处理产品将为更多的人提供 有机会过上更健康的生活，并将通过增加现有的 饮用水资源。饮用水污染是一个古老的问题， 近几十年来，人造毒素（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、雨水以及污染的空气和土壤。暴露于这些毒素通过 饮用水导致慢性、复杂的疾病;其负担主要落在福尔斯身上 社会经济弱势群体。去除这些有毒化合物是 必须保护健康。 传统的吸附技术相对简单且成本效益高， 具有结构复杂性，以允许同时去除广泛的 有毒有机化学品其他净化技术（即反渗透膜和 羟基自由基）未能为居民区提供简单且成本有效的方法 去除饮用水中的各种有机化学物质。是什么 在价值30亿美元的美国住宅处理市场中，缺少一种简单且具有成本效益的POU 该产品用于同时去除有毒有机和无机污染物。 通过这个SBIR项目，Chemica旨在为水领域带来一个及时的新工具 特别针对难以以易于使用的方式去除污染物的处理/纯化 和负担得起的方式。这将通过应用Chemica的专有表面 改性技术，以坚固的碳纤维基板。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。通过以前的努力， 已经开发出针对有机毒素或无机毒素的吸附剂。我们的目标是 SBIR计划旨在开发一种能够同时吸附两种有机物的吸附剂 和无机毒素在一个高效的机制，这将通过实现 具体目标：1。离子液体辅助功能化纤维的制备 2.活性炭纤维去除有毒有机和无机化学物的特性。 关键词：饮用水，新兴污染物，毒性，吸附剂，碳纤维， 药品、增塑剂、杀虫剂、消毒剂副产品、重金属、铅， 配位化学，有机化学，VOC，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.
