Preparations and Characters for Acetamiprid of Molecular Imprinted Polymer Electrochemical Sensors
摘要
Abstract
A novel molecularly imprinted membranes electrochemical sensor with good memory capacity to acetamiprid was developed.Based on electrodeposition technique,chitosan was deposited onto the surface of gold electrode as a functional polymer matrix along with aimed molecules acetamiprid and glutaraldehyde as a crosslinking agent.Cationic probe Ru（NH3）6Cl3 was employed to indirectly investigate the electrochemical electrochemical response characteristics as well as the imprinted effect of the sensors.The results showed that the sensors had a specific recognition to acetamiprid compared to the structural similarity midacloprid and other pesticide.There is more sensitive response to acetamiprid at imprinted sensors than that at nonprinted sensors with a good linearity over the concentration range of 1.0×10-7~2.0×10-5 mol/L.The prepared sensors can be exploited for the separation and analysis performing simultaneously to acetamiprid in the pesticide residue samples.关键词
