Recycling of Agriculture Wastes for Efficient Removal of Methyl Orange Dye Using Batch Adsorption Unit

The main purpose of this study is to exam the ability of agriculture wastes without pretreatment such as date palm fibers (DPF), sawdust (SD), rice husk (RH) as low-cost adsorbents for removing of methyl orange dye (MO) from industrial wastewater. The operating parameters were designed under isother...

Description
Summary:The main purpose of this study is to exam the ability of agriculture wastes without pretreatment such as date palm fibers (DPF), sawdust (SD), rice husk (RH) as low-cost adsorbents for removing of methyl orange dye (MO) from industrial wastewater. The operating parameters were designed under isothermal batch conditions to study the influence of pH (2-10), initial concentration of MO dye (100-500) mg/l, adsorbent dose (0.1-1) g/100 ml and contact time (10-150) min. The optimum conditions were pH = 2, the initial concentration of dye = 100 mg/l, the amount of adsorbent dose = 0.6 g/100ml and 120 min contact time. At these conditions, the maximum removal efficiency was 95%, 86% and 77% for DPF, SD, and RH, respectively. There are two advantages to this work, it can remove MO dye from wastewater and disposal of agricultural wastes. The equilibrium results were compared with the most common isotherm adsorption models, Langmuir and Freundlich models, to measure the conformity of results obtained. It was fitted with the two models with a high correlation coefficient (R2) for all adsorbents.
