Arsenic Selective Ligand-Anchored Fiber for Purification of Drinking Water

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 Produce a manufacture ready POU cartridge which meets defined commercialization requirements Prepare a comprehensive patent landscape report Prepare a comprehensive customer and competition analysis Key words arsenic drinking water toxicity adsorbent carbon coordination chemistry organic chemistry separation selective robustnessProject Narrative Arsenic As has been identified as the number one most hazardous substance on the CERCLA Priority List of Hazardous Substances ATSDR Today arsenic poisoning is one of the major environmental threats worldwide as millions of human beings have been exposed to excessive As through contaminated drinking water Our technology will allow communities of all sizes a simple and cost effective source of arsenic free drinking water
