“…Carbon nanotubes (CNTs) have recently been used in carbon paste electrodes [8][9][10][11]. CNTs have very interesting physicochemical properties, such as an ordered structure with a high aspect ratio, ultra-light weight, high mechanical strength, high electrical conductivity, high thermal conductivity, metallic or semi-metallic behavior and high surface area [12].…”

“…Carbon paste electrodes have been widely applied in electrochemistry because of their advantages over membrane electrodes such as ease and speed of preparation, renewability, stable response, porous surface, low cost, low ohmic resistance [16][17][18][19]. Usually, the carbon paste consists of graphite powder dispersed in a nonconductive mineral oil.…”

Carbon Paste Electrode Modified by silica gel /MWCNTs was manufactured and used for the electrochemical determination of Ascorbic acid (AA) in acetate buffer (pH=5.0) using cyclic, linear sweep voltammetry and square wave voltammetry(CV, LSV, and SWV). The results illustrated that the carbon paste modified electrode give a good response for an electrocatalytic activity toward the oxidation of AA. The electrochemical oxidation of AA at modified carbon paste electrode was diffusion-controlled and irreversible, using the optimum conditions to achieve the lower detection limit 1.07 × 10-8 M, good reproducibility, and high stability. This method has been applied to the determination of AA in orange and lemon fruits, and the recoveries were from 96% to 102%.

In this study, the main purpose is to fabricate a sensitive and selective electrochemical sensor through the multiwalled carbon nanotube-graphite/Ag electrode (MWCNTs-G/Ag). The application of this sensor was developed for the determination of diclofenac sodium in pharmaceutical dosage form, urine and human plasma. MWCNTs-graphite mixture improved the electroactive surface area due to its porous structure and a remarkable increase in the peak currents was observed. It demonstrated a catalytic effect and speeded up the rate of redox process. Application of MWCNTs-G/Ag resulted in a sensitivity augmentation. It is found that a maximum current response for the sensor in the Britton-Robinson buffer solution can be obtained in pH 3. The prepared sensor showed good standard calibration curves during 3 consecutive days over the concentration range of 45-2000 ng/mL and RSD values ranging from 1.95-7.11%. The limit of quantitation and detection limit were 45 and 15 ng/mL, respectively.
