Abstract

A new two-dimensional (2D) terbium(iii) coordination polymer (1) was successfully fabricated by a solvothermal reaction. Luminescence spectra measurements show that 1 can selectively and sensitively detect Fe3+, CrVI (CrO42-/Cr2O72-), and picric acid (PA) in aqueous solution. The limits of detection (LODs) of 1 toward Fe3+, CrVI, and PA are calculated to be 50, 100, and 50 nM, which are significantly lower than the U.S. Environmental Protection Agency's (USEPA) proposed concentrations in drinking water. More significantly, 1 can be easily recycled at least 5 times in the detection process of CrVI (CrO42-/Cr2O72-) and PA through simple processing. For all we know, 1 is the first multifunctional and recyclable Tb-CP, which displays highly selective and sensitive detection of Fe3+, CrVI (CrO42-/Cr2O72-), and PA in aqueous media.
