A copper( ii )-based metal–organic framework: electrochemical sensing of Cd( ii ) and Pb( ii ) and adsorption of organic dyes

in mineral water, tap water, and river water with satisfactory recoveries. Additionally, the adsorption performance for organic dyes has been studied in detail using Cu-L as an adsorbent. The results indicate good adsorption selectivity for methylene blue (MB) and neutral red (NR) compared to methyl orange (MO) and rhodamine B (RhB) molecules.
