Abstract

In this project, two types of the electroanalytical methods have been studied, which are the Differential Pulse Polarography_ (DPP) and Differential Pulse Stripping Voltammetry (DPSV). The DPP mode is used to identify the half-wave potential for the metals, including the lead, cadmium, and zinc. The DPP mode is also used to determine the detection limits for the lead, cadmium, and zinc. Meanwhile, the DPSV mode is used to identify the half-wave potential for the metals. The optimum conditions for the DPSV has to be determined, in order to be used to determine the concentrations of the lead, cadmium, and zinc in Sungai Pencha1a. The DPSV mode is also used to determine the detection limits for the metals. The concentrations for the metals are obtained by the external calibration method. The project is stressed on the linear relationship between the peak current and the concentrations, optimum conditions for the DPSV, and the detection limits for the DPP mode and DPSV mode.
