Arsenic Selective Ligand-Anchored Fiber for Purification of 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，并通过增加可获得性来加强社区 清洁的水资源。今天，砷中毒是主要的环境问题之一。 随着数百万人暴露在过量的砷中，全球范围内的威胁 通过受污染的饮用水。砷的严重毒性一直很好。 有记录在案。在世界范围内，社区需要新的分离技术来 去除饮用水中的砷。目前正在开发的常规吸附剂技术 用于修复受砷污染的水在以下方面有各种限制 容量、选择性和稳健性。一种新型除砷装置的研制 介绍了一种基于新型纤维基吸附剂的饮用水处理技术。 在这个SBIR计划中提出的。 在第一阶段计划中，使用一种新的类别的 用于饮用水净化的砷选择性配基锚定纤维， 演示了。在第二阶段计划中，纤维吸附剂进一步开发为 新型高含砷饮用水除砷技术的基础 处理能力强，选择性好，在较宽的pH范围内均能有效提高 与离子交换、激活等传统技术相比的稳健性 氧化铝和其他材料。通过与潜在合作伙伴的广泛讨论，我们拥有 确定了在第三阶段之前需要达到的几个商业化里程碑 可以实现资金和许可。 该方案的目标将通过以下具体目标实现： 1.生产满足定义的商业化的可生产的POU墨盒 要求。2.编制一份全面的专利版图报告。3.准备一份 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.
