Improper discharge of dye pollutants into the environment is a crucial issue in many countries. Multiple methods have been explored to remove dye pollutants, including physical, chemical, and biological approaches. This study aims to investigate the potential of pre-treated local fruit peels in removing toxic dyes. In this study, mango and jackfruit were used as adsorbents for the remediation of methylene blue (MB). The fruit peels undergo different treatments, followed by UV–vis and FTIR analyses to determine the sorption of MB. Findings showed that jackfruit treated with methanol and autoclaved mango peels demonstrated superior removal with 88.8% and 82.1% decolorization efficiency (DE), respectively. Further analyses confirmed the occurrence of sorption via the reduction of absorption peaks and identification of a higher number of functional groups. Therefore, this study revealed the pre-treated mango and jackfruit capacity as potential adsorbents for removing toxic dyes. Copyright © 2023 Elsevier Ltd. All rights reserved.
