عنوان انگلیسی The Application of Sio2 Nanoparticles for Anionic Dye Removal from Aqueous Solution
چکیده انگلیسی مقاله Background & Aims of the Study: Dyes are one of the widespread chemicals which may have many adverse effects on life cycle. Thus, this study was conducted to survey the RB19 dye removal efficacy from aqueous solution, using the SiO2 nanoparticles. Materials and Methods: This study was an experimental-lab study. The batch adsorption system were utilized to evaluated the RB19 dye removal efficiency under different amount of effective parameters including contact time, pH, adsorbent dosages, initial RB19 dye concentration and temperature. Results: the results of this study showed that the increasing of contact time, adsorbent dosage and temperature (up to 30) can positive effect on dye removal efficiency and can develop the dye removal efficiency, while the increasing of pH and RB19 dye concentration decrease the dye removal efficiency. The maximum dye removal efficiency was observed to be 95.72% at pH=5 and temperature of 30. Furthermore, the equilibrium studies of the RB19 dye adsorption depicted that the Langmuir isotherm and pseudo-second-kinetic models was successfully able to describe the equilibrium data. Conclusion: It can be concluded that SiO2 nanoparticles are excellent adsorbent to remove the dyes from aqueous solution.
