Aerogels, with their high porosity and good mechanical properties have great potential for use as filtration media. Poly(ethyleneimine) (PEI) Figure 1. <img src='https://acs-archive-assets2.s3.amazonaws.com/239nm/uploads/16322__figure_1_.jpg' alt='' /> aerogels cross-linked with 1.4-butanedioldiglycidylether (BDGE) were investigated as filters. Sunscreen was chosen as a water contaminant because of the developmental toxicity posed by the UV absorbing compounds it contains [1-3]. A solution of sunscreen and water was passed through PEI aerogel monoliths, and the filtrate was analyzed via UV/VIS spectroscopy for UV active content. By further tailoring the functional groups on PEI aerogels, the filter properties can be further improved. 1. Schlumpf, M.; Kypke, K.; Voekt, C.; et al.
