| Summary: | Dye is a widely used product in many industries that produce coloured goods. The byproduct discharge after the colouring process finishes will contribute to dye pollution in wastewater thus polluting the water bodies nearby the areas of discharge. To treat the pollution due to dye like methylene blue (MB), adsorption is the most common treatment where natural adsorbents like dragon fruit peels (DFP) and pineapple crown leaves (PCL) have the potential to do so. The physical characterization of the DFP, and PCL was then analysed by scanning electron microscope. Batch adsorption experiment was adopted where the hybrid adsorbents of DFP and PCL were recorded successfully removed 84 to 92 percent of MB at 140 minutes. The removal was determined by using two different parameters which were varied dosage and contact hour. Adsorption isotherm models such as Langmuir and Freundlich Isotherm were being used along with kinetic analysis, Pseudo-First and Pseudo Second order in this study. At the end of this study shows that natural adsorbents such as DFP and PCL can be one of the alternatives to treat water pollution due to effluents from industry in the wastewater at the treatment plan. © 2024 Institute of Physics Publishing.
