Description
Summary:Lead is a heavy metal that pollutes the environment. The main source of lead pollution is from motor vehicle exhaust emissions and industrial wastewater such as the battery manufacturing industry and the paint industry. Apart from being an environmental polluter, this element damages the nervous system and disrupts the function of enzymes in the body. Lead is very dangerous, especially for children because it can interfere with brain growth. Therefore, an analytical method with high sensitivity is needed to determine lead levels. In this study, the levels of lead in the soil were analyzed by the Anodic Stripping Voltammetry (ASV) using copper amalgam electrodes as working electrodes, Ag/AgCl as reference electrodes, and platinum wire as auxiliary electrodes. This research consists of 3 main stages, namely the preparation of working electrodes and references electrode along with their characteristics, testing the performance of the electrodes, and analyzing the sample. The Ag/AgCl reference electrode has been successfully prepared and ready to use, but the last two steps have not been carried out. Results of the literature study show that it is possible to measure lead using the ASV technique using copper amalgam electrode.
