Abstract
A new strategy was developed for the construction of a multilayered chemical modified electrode. The electrode was modified with two layers of carbon nanotubes conglutinated by polydopamine embedded with β-cyclodextrin. The practicability of the designed electrode was validated by the determination of catechol as a model molecule. Using the multilayered electrode, the redox peak currents in cyclic voltammetry for catechol were enhanced significantly compared with an electrode modified with single-layer carbon nanotubes. With the amount of added β-cyclodextrin and pH optimized, the peak currents showed good linear relationship with concentrations of catechol in the range from 2.50 × 10−7 to 4.00 × 10−3 mol·L−1 with a detection limit of 4.00 × 10−8 mol·L−1 based on a signal-to-noise ratio equal to three. The recovery values for spiked tap water and lake water were also satisfactory.
