Pollution by textile dyes is one of the most relevant environmental problems due to its significant negative effects on the environment. In response to this, several remediation processes have been develop ed, with adsorption being an effective process for removing these contaminants from water. In addition, the use of natural adsorbents proves to be a cost-effective alternative to remove organic pollutants. In this research, the capacity of avocado seed as a bio-adsorbent for the removal of color from textile wastewater obtained from a textile company was evaluated. Using the Response Surface Methodology and a Central Composite Design, it was found that the factor with the greatest influence on the removal process was pH. In addition, at 20 °C, the optimum conditions to achieve the greatest color removal from the textile wastewater were pH=2, dosage of 20 g/L and a 30-minute agitation time. According to these conditions, 96.35% of the color of the wastewater was removed.
