Clean water is essential for all life forms to thrive, but when this life sustaining-source is contaminated by natural events or anthropogenic activities it becomes imperative to know the contaminant (detection) and rectify (decontamination) it to safe levels. Along with the regulated standards set by the U.S. Environmental Protection Agency (EPA) for heavy metals, charged or neutral organic contaminants,1, 2there is now a growing concern for chemical compounds for which there is little to no data on their health effects in potable water resources.3-10 Levels of different contaminants in water can show a presence from parts per billion (ppb) and upwards in concentration where current adsorbents used to remove contaminants suffer from low adsorption capacity, slow kinetics, poor selectivity, and moderate/weak affinity. Hence, there is a need to develop new types of adsorbent materials that have high uptake capacity, fast kinetic activity, strong affinity, and a broad acceptance to remove contaminants without removing beneficial trace elements that are essential for maintaining a healthy ecosystem. In this proposed research, we aim to develop functional porous organic polymers (POPs) as a new type of highly efficient and highly effective decontamination materials, which will not only circumvent the drawbacks of existing adsorbent materials but also offer new platforms for adsorption-based water purification.
