| 英文摘要 | A new electrochemical sensor for melamine with 3,4-dihydroxyphenylacetic acid as the recognition element is established. the results of fourier transform infrared (ft-ir) spectra demonstrate that melamine may interact with 3,4-dihydroxyphenylacetic acid to form a complex mainly through the hydrogen-bonding interaction. the electrochemical behavior of 3,4-dihydroxyphenylacetic acid in the presence of melamine was studied. the anodic peak currents of 3,4-dihydroxyphenylacetic acid obtained by differential pulse voltammetry are linear with the logarithm of melamine concentrations in the range from 1.0 x 10(-8) to 5.0 x 10(-6) m with a linear coefficiency of 0.997. the detection limit is 3.0 x 10(-9) m. the proposed method displayed an excellent sensitivity and was successfully applied to the determination of melamine in milk products.
