Abstract
A facile approach for ultrasensitively sensing tris(2,3-dibromopropyl) isocyanurate (TBC) was reported. Based on coupling molecularly imprinting with electropolymerization of ο -phenylenediamine (OPD), which is electro-active monomers, the poly-OPD film was deposited in an OPD solution by potentiodynamic cycling of potential (scan rate is 50mV/s) on a glassy carbon electrode. Using K 3 [Fe(CN) 6 ] as an electro-active marker, the properties of the TBC imprinting electrode were investigated by differential pulse voltammetry and amperometric i-t curve and exhibited an excellent imprinting effect. The results showed that a linear relationship between the value of peak current and the TBC concentration was found in the range of 1.4×10 −12 ~6.7×10 −12 mol/L and a low detection limit of 6.26×10 −13 mol/L for TBC determination.
