A fluorescent probe for a lewisite simulant†
Abstract
Herein, we report for the first time a highly sensitive fluorescent probe for the detection of an organoarsenic blister agent simulant, arsenic trichloride (AsCl3). This probe showed high selectivity to AsCl3, in the presence of other metal ions, even at low concentrations. Moreover, quantitative determination of AsCl3 in soil was achieved with a detection limit of 61.2 μmol kg−1 that is sufficiently lower than the reported LD50 of lewisite.
