Manila tamarind seed has been acid-modified in order to improve the biomass's remediation capabilities. Scanning electron microscopy analysis showed that chemically activated manila seed biomass was rough and porous, with voids present. The ideal circumstances for the eriochrome black and brilliant orange dye removal were found through batch investigations. The optimal values are adsorbent dosage – 3.5 g/L, temperature – 303 K, contact time – 50 min and 40 min, and pH – 6 and 9 for EB and BO dye respectively. Adsorption capacity of AAPDB for EB and BO dye was observed to be 97.12 mg/g and 113.43 mg/g respectively. The best fitting isotherm and kinetic models were Freundlich and Pseudo-first order denoting the multilayer adsorption. The artificial neural network model of both dyes' adsorption was used to link the experimental dye removal values with the anticipated values of the ANN. Better correlation was demonstrated by the neural network model, with values more than 0.94 suggesting that the model is appropriate for the current study. The potential of acid-modified manila tamarind seed biomass in the dye removal process was validated by modelling studies.
