Abstract

Lead electrochemistry sensor had been developed using screen printed electrode (SPE) technique with poly(vinyl) chloride (PVC) as printed matrix. The study has been carried out by using different type of electrodes. However, lead electrochemistry sensor had optimum response when deposited with mercury on the top of working electrode and in the buffer solution of pH 2. The optimum parameters for mercury deposition include deposited time = 15 s, deposited potential = 1000 mV, scanning range = 20 mV/s and amplitude pulse = 25. This sensor has linearity range of 1 - 50 ppm of Pb(II) R² of 0.9997. The LOD of this sensor is lower than 1 ppm of Pb(II).
