It also contributes to the damage of the environment. This study examines the adsorption biochar made from Annona reticulata to remove azo dye from textile wastewater. To improve the adsorption capacity, biochar valorized by chitosan molecules, Investigations were conducted on the use of chitosan-based materials that are acid-resistant for azo dye adsorption. In the batch experiment, basic operating parameters such as initial Azo dye concentrations, pH, contact time and bed height were assessed. The percentage removal efficiency for Azo dye was recorded as 67.18%, 75.88% and 94.37% for three dissimilar sized columns that were 6cm, 8cm, and 10cm. The UV–visible absorption spectroscopy was used to quantify the decolorization of dyes. The changed surface properties of the adsorbent produced from Annona reticulata were characterized by using SEM, XRD, and FTIR. The effectiveness of the column's adsorption was calculated mathematically by Yoon-Nelson, Thomas, and Adams-Bohart models. The model that best represents equilibrium isotherm data by adsorption had R2 values of 94.63, 86.67 and 96.35 respectively.</p> </p></abstract><publication_date><month>04</month><day>18</day><year>2023</year></publication_date><pages><first_page>109</first_page><last_page>118</last_page></pages><publisher_item><identifier id_type="pii">gnest_04882</identifier></publisher_item><doi_data><doi>10.30955/gnj.004882</doi><timestamp>1714025233</timestamp><resource>https://journal.gnest.org/publication/gnest_04882</resource></doi_data></journal_article></journal></body></doi_batch> </div>
