项目摘要

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.

项目概要此次SBIR项目开发的水处理产品将为更多的人带来过上更健康生活的机会，并将通过增加可用的资源来加强社区饮用水源污染是一个长期存在的问题。近几十年来，人造毒素（药物、增塑剂、农药、消毒剂副产品等）通过废水进入饮用水水库，通过农业径流、雨水以及污染的空气和土壤接触这些毒素。饮用水会导致慢性、复杂的疾病，而这些疾病的负担主要落在人类身上；消除这些有毒化合物是社会经济弱势群体的任务。保护健康势在必行。传统的吸附技术相对简单且具有成本效益，但具有复杂的结构，可以同时去除多种其他净化技术（即反渗透膜和羟基自由基）未能为住宅区提供简单且具有成本效益的手段去除饮用水中目前发现的许多不同的有机化学物质。价值 30 亿美元的美国住宅治疗市场缺少的是简单且具有成本效益的 POU 用于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 旨在为水领域带来及时的新工具专门针对难以去除的污染物的处理/纯化，易于使用这将通过应用 Chemica 的专有表面来实现。对坚固的碳纤维基材进行改性技术很容易。通过之前的努力，Chemica 可以进行扩展并进行定制以满足用户的特定需求。已开发出针对有机毒素或无机毒素的吸附剂。 SBIR计划是开发一种能够同时吸附两种有机物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. ACF 去除有毒有机和无机化学品的表征。关键词: 饮用水, 新出现的污染物, 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
