摘要：

As a priority pollutant in the environment, hexavalent chromium (Cr(vi)) has received increasing attention. In this work, a safe, simple, low-cost, effective and sensitive colorimetric strategy for the determination of Cr(vi) was introduced based on polyvinylpyrrolidone (PVP) functionalized silver nanoparticles (PVP-AgNPs). The prepared PVP-AgNPs had good dispersibility, and exhibited a state change from dispersed to aggregated when Cr(vi) was present in pH 5.5 PBS buffer due to the special and strong coordination between PVP and Cr(vi), accomp...
