K۳Fe(CN۶) doped Cu-BTC metal-organic framework as a novelelectrocatalyst for determination of bisphenol A

We report the construction of Fe(CN)۶۳--doped copper-۱,۳,۵-benzenetricarboxcylic acid metal-organicframework (HCF/Copper-BTC). The characterization results confirmed the successful doping ofFe(CN)۶۳- in the pores and voids of Cu-BTC. Factors affecting the doping, including the concentrationof HCF, temperature, and time were optimized. The HCF-modified sensor (CPE/HCF- Cu-BTC)presents extraordinary electrocatalytic activity toward ultra-trace amounts of bisphenol A.Electrochemical tests verify that incorporation of HCF ions in the pores and voids of Cu-BTC MOFincreases the sensitivity of the sensor toward ultra-trace amounts of BPA.
