In recent years, chemically modified electrodes are more attracted in the field of electro analytical chemistry for the past three decades. These chemically modified electrodes could be used in sensor applications, storage, molecular electronics, and environmental pollutant monitoring purposes, electro-chromic displays and electro-organic syntheses [1]. Currently, these chemically modified electrodes can be modified by four routes of ways such as redox polymer coatings, covalent modifications, heterogeneous multilayer modification and chemisorption. Chemically modified electrodes has unique features than other modified electrodes because these chemically modified electrode has a very thin film on the electrode surface, the selected chemical is coated on the top of the electrode by drop casting method or electrode position methods which conducts electron transfers very fast and sensitively compared with other modified electrodes.
