Zhan MH, Yu HM, Li LH, Nguyen DT, Chen W (2019) Detection of hexavalent chromium by copper sulfide nanocomposites. The method was applied to the determination of total Cr in environmental water samples. The signals can be observed by the naked eye under UV light of 365 nm. The luminescence probe for Cr 3+, CrO 4 2−, and Cr 2O 7 2− shows low detection limits (0.15 μM, 0.17 μM, and 0.13 μM, respectively), relatively broad linear ranges (0.6–150 μM, 0.1–200 μM and 0.4–180 μM, respectively), and high quenching constants K SV. The Eu can be considered as a highly selective and sensitive recyclable luminescence probe for sensing Cr(III) and Cr(VI) based on strong luminescence quenching effects it can be recycled at least five times. The luminescent properties of Eu were measured and investigated in detail, which demonstrated that Eu not only possessed excellent water and chemical stabilities in a wide pH range (5–10) but also displayed red luminescence with excitation/emission maxima at 332/617 nm. An Eu(III)-functionalized strontium-organic framework (Eu was synthesized by encapsulating Eu 3+ ions into the pores of Sr-MOF via postsynthetic modification (PSM) and fully characterized by XRD, SEM, EDS, FTIR, and TGA.
