    Industrial waste contaminated with hexavalent chromium, Cr(VI), has a significant impact on the environment and human health. In the environment, Cr(VI) is highly toxic to aquatic organisms, affecting biodiversity and water quality. Additionally, it can contaminate soil, impairing plant growth and food production. Its persistence in the environment exacerbates its potential for long-term accumulation. Regarding human health, industrial workers exposed to Cr(VI) face severe occupational risks, including lung cancer and skin and respiratory irritations. Contamination of drinking water with hexavalent chromium poses a public health threat, with chronic exposure linked to stomach cancer and damage to internal organs. Furthermore, Cr(VI) can accumulate in aquatic organisms, introducing it into the human food chain. Given this environmental issue, remediation strategies, such as adsorption using adsorbent materials, are essential for containment. This study aims to promote the removal of Cr(VI) through an adsorption process, using biochar from coffee husks modified with zero-valent iron nanoparticles as the adsorbent material.
