| Abstract: | A MC-LR molecularly imprinted electrode was prepared by cyclic voltammetry on a gold electrode surface electric polymer into a polypyrrole film in the presence of template molecular,Microcystin(MC-LR).On the basis of the conditions of the optimal preparation,the characteristics of sensor such as linear relationship,service life and selectivity were investigated.Results showed that the sensor exhibited a good selectivity and sensitivity,in the concentration range of 0.05~0.30 μg/mL showed good linear relationship,with the relative error as 3.2%,recovery 91.0%~103% and detection limit of 0.009 4 μg/mL. |
