Sun DT, Peng L, Reeder WS, Moosavi SM, Tiana D, Britt DK et al (2018) Rapid, selective heavy metal removal from water by a metal-organic framework/polydopamine composite. It is perceived that this design concept will open up a fresh insight of simple, rapid and reliable detection of other heavy metal ions in drinking water and environmental samples. The lower limit detection is 0.27 μM. This assay exhibits excellent selectivity for Cu 2+ over other environmental metal ions. Simultaneously, the solution color changes from dark yellow to colorless. When Cu 2+ is introduced into this silver nanoplate system, Cu 2+ can oxidize I − to iodine (I 2), which can further oxidize silver to form silver iodide (AgI). Further, silver nanoplates coupled with iodide ions are employed for the colorimetric determination of copper ions (Cu 2+) based on a new strategy of fusion/oxidation etching nanoplates. This system shows excellent selectivity in the presence of a variety of other metal ions. Cr 3+ can cause aggregation through high affinity between Cr 3+ and carboxylate groups of citrates, resulting in a color change from dark yellow to purple and at last colorless. Citrate-capped silver nanoplates are applied for the detection of chromium ions (Cr 3+) based on aggregation of silver nanoplates. The authors have studied the role of different ligands on the surfaces of silver nanoplates for regulating their analytical applications.
