Kinetic and Thermodynamic Studies on the Adsorption Behavior of Crocein Orange G Dye Using Casuarina Equisetifolia Bark Carbon
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
The adsorption behavior of crocein orange G dye from aqueous solution was investigated using Casuarina equisetifolia bark carbon. The effect of various experimental factors such as pH, adsorbent dose, initial dye concentration, contact time and temperature were studied by using the batch technique. The adsorption capacities were evaluated by using Langmuir and Freunlich adsorption isotherm models. Thermodynamic parameters were calculated and it was found that the adsorption of crocein orange G (COG) dye using Casuarina equisetifolia bark carbon (CEBC) was endothermic and adsorption process. Pseudo first order, Pseudo second order models were also used to describe the kinetic data. The adsorbent surface functional groups identification with Fourier Transform Infrared (FTIR) spectroscopy and the morphology of the surface are identified with Scanning Electron Microscope (SEM).
