Rhodamine B adsorption by activated carbon: Kinetic and equilibrium studies

A carbonaceous adsorbent (TPC) prepared from Thespusia populinia bark by acid treatment was tested for its efficiency in removing Rhodamine B (RDB). The parameters studied include agitation time, initial dye concentration, carbon dose, pH and temperature. The adsorption followed first order reaction equation and the rate is mainly controlled by intra-particle diffusion. Freundlich and Langmuir ...

Kinetic, Thermodynamic and Isotherm Studies on the Removal of Rhodamine B dye using Activated Carbon

The research of the present work was to investigate the removal of Rhodamine B dyes from aqueous solution by using Activated Acacia Nilotica Shell Carbon (ANSC). Generally, dyes are organic compounds used as colouring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the indus...

Thermodynamic and Kinetic Studies: Adsorption of Fe (III) onto Corncob

Heavy metals released into the surface and ground water has been a major preoccupation for many years because of their increased discharge, acute toxicity, non-biodegradable nature and tendency for bioaccumulation [1-3]. Iron a common contaminant enters the water bodies through effluents of industries such as electroplating, mining, steel processing etc. The presence of Fe (II) in water results...

Preparation and Characterization of Modifed PEEK-WC: DEHPA Microspheres for Rhodamine B Adsorption. Kinetics Studies

Functionalized polymeric microspheres based on a modifed polyether ether keetone (PEEK-WC) using immersion precipitation techniques were successfully prepared by doping initial polymeric solutions with DEHPA. The viscosity of the doping solution was measured for determining the optimal value for obtaining reproducible capsules. The modifed microspheres were characterize...

Nanodimensional AlMCM-41 material for adsorption of dyes: Thermodynamic and kinetic studies

AlMCM-41 was applied for adsorption of methylene blue (MB) and auramine (AU) in single and binary component systems. In the single component systems, AlMCM-41 represents higher adsorption capacity for MB than AU with the maximal adsorption capacity of 2.07×10−4 and 1.15×10−4 mol/g at 25 ˚C for MB and AU, respectively. In the binary component system, MB and AU exhibit compe...
