Research on zeolite/clay/activated charcoal composites as Hg heavy metal adsorbents has been carried out. Zeolite and clay were previously activated using NaOH while activated charcoal was activated using HCl. The adsorbent characterization was carried out by Fourier Transform Infrared Analyzer (FTIR), X-Ray Diffraction (XRD), and mercury levels using Atomic Absorption Spectroscopy (AAS). Hg metal adsorption experiments were carried out by varying the composition of zeolite / claystone / activated charcoal. The location of the study was in Gold Mining without Permit (PETI) in the Kapuas Sub-watershed, Ulak Jaya Village, Sintang. The results showed that zeolite / claystone / activated charcoal succeeded in reducing mercury levels in mining waste.
