Keyword : activated charcoal, adsorbent, fiber, iron, well water, AAS Excess iron content in well water can affect the quality of clean water and will have an impact on human health such as indigestion, poisoning, intestinal damage, bleeding gums, and arthritis. The immobilization of activated charcoal from refill water and coconut shell on yarn is an alternative adsorption method to reduce iron II (Fe2+) content in well water in the form of a fiber filter that is easy to apply and separate. The purpose of this study was to determine the capacity and efficiency of adsorption on the absorption of ferrous metal with various contact times of 10, 20, 30, 60, and 120 minutes. The research process began with the manufacture of activated charcoal, characterization of activated charcoal, manufacture of activated charcoal immobilized yarn, and testing of the absorption of activated charcoal against iron(II). Opening pores on activated charcoal used by refill water and activated coconut shell with 6M and 0,1M HCl solutions. Activated charcoal immobilized yarn was made with 100 mesh activated charcoal powder attached to the yarn using the best concentration of tapioca adhesive, which was 10%, which was obtained from tests of stability, thickness and surface homogeneity of the yarn. The surface pores of activated charcoal immobilized yarn were viewed using a scanning electron microscope (SEM). The results of the test of the highest adsorption capacity in well water were obtained at 30 minutes with an adsorption efficiency of coconut shell activated charcoal of 98,33% and activated charcoal used by refilled water of 97,08%. The results of the measurement of levels of iron metal II (Fe2+) using atomic absorption spectrophotometry (AAS). The isotherm equation of the two adsorbents immobilized activated charcoal used refill water and coconut shell followed the Freundlich isotherm with R2 values close to 1, namely 0,9976 and 0,9961
