A facile and sensitive tetrabromobisphenol-A sensor based on biomimetic catalysis of metal-organic frameworks: PCN-222 (Fe)

Abstract

A facile electrode based on metal-organic frameworks (PCN-222(Fe)) and acetylene black was fabricated for sensitive detection of tetrabromobisphenol-A (TBBPA). As a heme-like enzyme mimics, PCN-222(Fe) exhibited excellent peroxidase-like catalytic activity, which could enhance the electrocatalytical activity towards the oxidation of TBBPA. Besides, on account of the ultra-high surface area and large pore volume, PCN-222(Fe) could intensively adsorb TBBPA from the aqueous solution and improved the sensitivity of the proposed senor. Upon optimized conditions, a linear range of 0.001-1.0 ┬Ámol L-1 was obtained for the detection of TBBPA, with a detection limit as low as 0.57 nmol L-1. Furthermore, the sensor was successfully employed to detect TBBPA in water samples, providing a promising alternative for practical application.
