Adsorption Kinetics and Equilibrium Studies of Reactive Red 198 Dye by Cuttlefish Bone Powder
In this research, the removal of Reactive Red 198 dye (RR-198) by Cuttlefish bone powder was investigated. The adsorbent was prepared in laboratory conditions and ground by ASTM standard sieves (60-100 mesh). The progress of the process is monitored spectrophotometrically by measuring the absorbance of dye at 518 nm wavelength. In addition, the effects of process parameter...
متن کاملKinetics, Thermodynamics and Equilibrium Studies on Adsorption of Reactive Red 198 from Textile Wastewater by Coral Limestone as a Natural Sorbent
Abstract Introduction: Dyes are among the most hazardous chemicals in industrial wastesdue to their toxicity for aquaculture, reduction of light permeability, and in turn development of disorders in photosynthesis process. The current study aimed to investigate the efficiency of coral in removing red reactive 198 from textile dye wastewater was investigated. Materials & Methods: In this e...
متن کاملSynthesis of Magnetic Graphene Oxide Nanocomposite for Adsorption Removal of Reactive Red 195: Modelling and Optimizing via Central Composite Design
In this work, magnetic graphene oxide (MGO) was prepared by in situ synthesis of magnetite nanoparticles in the presence of graphene oxide (GO). The prepared nanocomposite was characterized by applying scanning electron microscopy (SEM), X-ray diffraction (XRD, Fourier transform infrared spectroscopy (FTIR) and vibrating sample magnetometer (VSM). MGO was applied as an ...
متن کاملAdsorption Rate of 198 Reactive Red Dye from Aqueous Solutions by using Activated Red Mud
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 r...
متن کاملinvestigation of kinetics and equilibrium isotherms of direct red 12b dye adsorption on hazelnut shells
in this work, efficiency and performance of hazelnut shells (hs) adsorbent was examined for the removal and recovery of direct red 12b (dr12b) from wastewater. the absorbance of dr12b was measured spectrophotometrically at λmax=523 nm before and after adsorption of dr12b. the maximum removal was 99.8% for 30 mg l –1 ofdr12b concentration on 0.3 gr hs adsorbent. acidic ph was favourable for the ...
