摘要：

We have developed a novel nitrite sensor based on the immobilization of nanometer-sized gold colloid attached to an ethylenediamine monolayer-modified electrochemically pretreated glassy carbon electrode. The electrochemical behavior and mechanism of the modified electrode towards the reduction of nitrite was studied. The electrode exhibited sensitive response to nitrite with a detection limit of 4.5 x 10(-5) M (S/N = 3) and a linear range from 1.3 x 10(-4) M to 4.4 x 10(-2) M. The method was successfully applied to the detection of nitrite in real samples.
