چکیده
|
The electrocatalytic oxidation of dopamine at alizarin and triton x-100 modifiedcarbon paste electrode has been studied by means of cyclic voltammetric technique in 0.2 macetate buffer solution at ph 7.0. this suggests the effectively of surface modification ofcarbon paste electrode by triton x-100 a non–ionic surfactant. cyclic voltammetricinvestigations demonstrated the improved responses of dopamine. the modified electrodeexhibited strong promoting effect and stability towards the detection of dopamine inmobilization and immobilization methods of surfactant. the presence of triton-x 100 on thealizarin modified carbon paste electrode showed excellent electrocatalytic effect towards thedetection of dopamine.
