Arsenic Selective Ligand-Anchored Fiber for Purification of 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 提供机会，让人们过上更健康的生活， 清洁水资源。今天，砷（As）中毒是主要的环境污染之一， 由于数百万人暴露在过量的砷中， 通过被污染的饮用水。砷的严重毒性已被人们很好地认识到 记录在案。在世界范围内，社区需要新的分离技术， 从饮用水中去除砷。目前的常规吸附剂技术 用于砷污染水的修复有各种限制， 能力、选择性和稳健性。新型除砷剂的开发 一种基于新型纤维基吸附剂的饮用水处理技术， 在这个SBIR计划中。 在第一阶段计划中，使用一种新的 砷选择性配体锚定纤维用于饮用水净化， 演示。在第二阶段计划中，纤维吸附剂被进一步开发为 为饮用水的创新除砷技术提供了基础， 容量大，选择性好，在较宽的pH范围内有效， 与常规技术如离子交换、活化 氧化铝等。通过与潜在合作伙伴的广泛讨论， 确定了在第三阶段之前需要达到的几个商业化里程碑 可以获得资金和许可。 该CRP方案的目标将通过以下具体目标实现： 1.生产符合规定商业化要求的可重复使用的POU卡匣 要求. 2.准备全面的专利景观报告。3.编写一份 全面的客户和竞争分析。 关键词：砷，饮用水，毒性，吸附剂，碳，配位化学， 有机化学，分离，选择性，稳健性

Project Summary The water treatment product developed in this SBIR program will give more people the opportunity to live healthier lives and strengthen communities by increasing available clean water resources. Today, arsenic (As) poisoning is one of the major environmental threats worldwide as millions of human beings have been exposed to excessive arsenic through contaminated drinking water. The serious toxicity of arsenic has been well documented. Worldwide, communities demand novel separation technologies for the removal of arsenic from drinking water. Conventional adsorbent technologies currently in use for remediation of arsenic-contaminated water have various limitations in terms of capacity, selectivity and robustness. The development of an innovative arsenic removal technology for drinking water based on a new class of fiber-based adsorbent was proposed in this SBIR program. In the Phase I program, the technical and economic feasibility of using a new class of arsenic selective ligand-anchored fiber for purification of drinking water was demonstrated. In the Phase II program, the fiber adsorbent was further developed as the basis for an innovative arsenic removal technology for drinking water with higher capacity, good selectivity, effectiveness under the wide range of pH and enhanced robustness compared to conventional technologies such as ion exchange, activated alumina, and others. Through extensive discussions with potential partners we have identified several commercialization milestones which need to be met before Phase III funding and licensing can be realized. The goals for this CRP program will be achieved through the following Specific Aims: 1. Produce a manufacture-ready POU cartridge which meets defined commercialization requirements. 2. Prepare a comprehensive patent landscape report. 3. Prepare a comprehensive customer and competition analysis.
