Title
Removal of phosgene by metalloporphyrin-functionalized porous organosilicates
Abstract

This study sought to characterize the removal of phosgene by functionalized porous organosilicate sorbents. Metalloporphyrin variants were generated based on a Deuteroporphyrin IX 2,4 bis-ethylene glycol functionalized sorbent. The copper(II) variant removed phosgene at rates significantly higher than that of the bare sorbent. It was further demonstrated that the sorbent was reusable and that illumination resulted in additional target removal. The column effluent from the Cu(II) functionalized sorbent was shown to contain chloride; however, the levels were significantly less than would be expected based on a mass balance.
