The biomass adsorbent prepared from seeds of Annona Reticulata (custard apple) was used to remove Auromine-O dye from wastewater by adsorption. Effect of various experimental parameters such as initial concentration of dye, effect of pH, biomass dose and equilibration time were studied and properly examined. Batch adsorption studies were carried out at room temperature (30±10 c). At pH 7 the Auromine- O dye could be removed effectively by custard apple biomass. Mathematical equations have been designed for the wide range of applications. The results showed that the dye, Auromine-O strongly interacts with a biomass based adsorbent, the custard apple seeds powder.
