Adsorption of Congo red textile dye on pineapple activated charcoal

Year: 2025

Type: article

Abstract: The work produced activated carbon (CACCA) from the lignocellulosic biomass of pineapple peel and crown (CCA) by slow pyrolysis in a fixed bed reactor. Activation was carried out by water vapor at a temperature of 700 °C for a period of 30 min.. The objective was to remove the Congo red textile dye from the charcoal obtained. The biomass showed values for density 0.264 g/ mL, moisture 7.03%, volatilematter 80.74%, ash 6.33%, fixedcarbon 5.9%, carbon 43.43%, hydrogen 1.16%, oxygen 48, 19%, nitrogen 6.22%. The CACCA yield was 25.24%. The formation of a mesoporous structure of the activated cavão and pHpcz of the CACCA favored the adsorption process, which reached up to 94.94% efficiency in the removal of the Congo red dye.
