SUMMARY:

This study investigated the effectiveness of calcined yellow ipe fruit peel biomass as a bioadsorbent for the removal of Acid Red 447 dye from textile effluents. The material was processed without chemical activation, using calcination in a muffle furnace, and characterized by techniques such as SEM, XRD, FTIR and DLS, which indicated the presence of structural characteristics favorable to adsorption, such as a porous surface. In the adsorption tests, a 2³ factorial experimental design was used, which allowed determining the best conditions for dye removal. The best results were obtained with the following conditions: initial dye concentration (C₀) of 10 ppm, adsorbent dosage of 0.03 g/L, pH 10 and room temperature, achieving an average removal efficiency of 37.7. This value was obtained for Acid Red 447 dye, evidencing the performance of the bioadsorbent produced.
