It is quite important to research rapid and sensitive analytical method for ponceau 4R due to its adverse health effects. In this work, a kind of copper-based metal-organic frameworks were prepared using 1,3,5-Benzenetricarboxylic acid (H3BTC) as the ligand, and then used to construct a novel electrochemical sensing platform for ponceau 4R. The prepared Cu-BTC frameworks exhibit strong surface accumulation...
