- Abstract
Stearic acid modified glassy carbon electrode for the sensing of parathion and methyl parathion was fabricated. The electrochemical responses for parathion and methyl parathion were investigated by cyclic voltammetry, differential pulse voltammetry and amperometry. The results on stearic acid modified electrode and bare glassy carbon electrode were compared. Higher sensing current was obtained on stearic acid modified glassy carbon electrode. Analytical characteristics of the sensor such as sensitivity, linear dynamic range, lower detection limit and response time were evaluated.
