عنوان انگلیسی Adsorption Rate of 198 Reactive Red Dye from Aqueous Solutions by using Activated Red Mud
چکیده انگلیسی مقاله Backgroud and purpose: Dye is one of the problems of industrial effluent such as textile industries. The dyes can be removed by various methods. Therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. Materials and methods: This research was a lab study. Activated red mud was used as an adsorbent to remove reactive red 198 dye. The effect of various parameters on performance of adsorbent was investigated and the isotherm of adsorption was determined. The dye concentration was measured in wavelength of 518 nm by spectrophotometer. Results: The results indicated that the adsorption efficiency reduced by increasing of initial dye concentration. Increasing of contact time and adsorbent dose can lead to increasing of the removal efficiency. The maximum removal efficiency was occurred pH between 2 to 3. The data was best fitted on Frandlich and Temkin isotherms. Conclusion: The red mud had a satisfactory quality in dye adsorption. It can be used as effective and inexpensive adsorbents for treatment of textile effluent.
