Adsorptive Removal of Methylene Blue Dye Using Biowaste Materials: Barley Bran and Enset Midrib Leaf

In this study, several biowaste materials are screened for adsorptive removal of methylene blue (MB) from synthetic water. Among the tested adsorbents, barley (Hordeum vulgare) bran (BB) and enset (Ensete ventricosum midrib leaf, EVML) were selected further evaluation MB (a model cationic dye) adsorption. Batch adsorption performance BB EVML adsorbents was significantly high in a wide pH range (4-9). The well fitting experimental data with pseudosecond-order kinetic suggests monolayer MB. onto both fit Langmuir isotherm maximum capacities 63.2 mg/g 35.5 (EVML). exhibit considerable capacity dye (MB), perform under acidic basic conditions, reusable. Therefore, use these as may have an environmental benefit terms conversion wastes into valuable materials. Further studies suggested to investigate continuous mode using real wastewater.
