Journal Article

This paper describes the preparation of a hydrophilic copolymer membrane with two comonomers: 1-vinyl-2-pyrrolidone (commercial) and a new water insoluble piperazinedione derivative, which is a fluorogenic mercury sensing motif. The dense membrane permitted the fluorogenic detection of Hg²⁺ in aqueous media. The sensitivity of the membrane this cation was significantly high, with a detection limit of 10ppt. This limit of detection is much lower than that of DMSO/water solutions of the sensing monomer, which is 10ppb, and significantly lower than the maximum contaminant level (EPA) in drinking water, 2ppb.
