Iron (Fe) is one of the compounds contained in heavy metals which is very dangerous for the survival of living things when in the environment around the residence that has exceeded the threshold. Fe ions can cause turbidity, corrosion, and other impacts. Iron (Fe) is a transition metal and has the atomic number 26. The oxidation numbers of Fe are +3 and +2. Fe is an essential metal for the body which in high doses is toxic. Given the various dangers caused by exposure to Fe metal, it is necessary to treat Fe metal contained in groundwater. One of the most widely used heavy metal processing methods is the adsorption process. In previous studies, many adsorption processes used activated carbon from various materials as adsorbents. In this study, pectin was extracted from banana peels with hydrochloric acid as a solvent at various temperatures and concentrations. The optimum conditions were at 80oC and a concentration of 0.35 N. The pectin obtained was 2.3171 grams.
