Evaluation of Non-Imprinted Polymer Nanoparticles for Removal of Endocrine Disrupting Compounds from Surface Water and Wastewater
The objective of this study was to test the ability of non imprinted polymers (NIPs) for treatment of a variety of endocrine disrupting compounds (EDCs) for water and wastewater treatment, or water reuse. NIPs were tested with water spiked with a variety of EDCs. NIP were capable of removing greater than 99% of 17-β estradiol (E2), 99.7% of 17-α bisphenol A (BPA), 74.6 % of atrazine, and 44.8% of diethylstilbestrol. NIP particles were also tested for their ability to remove both remaining EDC concentrations as well as any daughter products formed for use as a polishing step following chlorination. Results showed that for chlorination of a 10 ppm E2 solution with 5 mg/L of chlorine and a 15 minute contact time, 5 mg/mL of NIP particles were capable of completely removing any residual E2 as well as daughter products which were formed.
