![]() Recent studies revealed that environmentally concerning concentrations of pharmaceutical pollutants were found in more than a quarter of 1,052 locations tested across 104 countries 6. EOCs include pharmaceuticals and personal care products, dyes, pesticides, and veterinary and industrial products 4, and their presence at concentrations on the order of micrograms to nanograms per litre can have negative effects on living organisms 5. While many pollutants are removed in conventional wastewater treatment plants (WWTPs), sequestration of emerging organic contaminants (EOCs) has proved challenging 3, 4. In addition, water plays an essential role in ecosystem balance and the continued preservation of biodiversity across our planet 2. ![]() SU-102 is synthesized from ellagic acid, an edible polyphenol building unit, highlighting the possibility of creating stable high-performance multi-functional materials from sustainably sourced plant-based components.Įnsuring the availability of freshwater is a fundamental challenge on a global scale, with 80% of the world’s population being at risk of water scarcity or insecurity 1. As a second mechanism of EOC removal, SU-102 photodegraded the antibiotic sulphamethazine under visible light. SU-102 adsorbs cationic EOCs with particularly high efficiencies, and of the 17 pharmaceutical EOCs detected in wastewater treatment plant effluent, all 9 cationic species were removed with efficiencies of at least 79.0–99.6%, emphasizing the importance of framework charge on selectivity. ![]() ![]() Here we developed a highly porous and stable zirconium–ellagate framework, denoted SU-102, which was used to remove EOCs from water, including real municipal wastewater treatment plant effluent. Emerging organic contaminants (EOCs), such as pharmaceutical compounds, are of growing environmental concern, and there is a need to develop new materials and technologies for their efficient removal.
