In this research, Loess Soil Nanoparticles (LSN), as a novel adsorbent nanocomposite was used for removal of green malachite (GM) dye from Aqueous Solutions by in a batch and fixed bed column. Firstly, LSN adsorption properties were investigated. The study investigates the effect of process parameters such as pH, adsorbent dosage, contact time and GM dye initial concentration. Next, GM dye was quantitatively evaluated by using the Langmuir, Freundlich isotherm and pseudo first and second order model. The adsorption data follow the adsorption equilibrium was described well by the Freundlich isotherm model. The results of SEM and AFM analysis show that particle size is less than 100 nm. Also, the BET analysis shows that the surface areas for LSN are 70 m2/g respectively. The results show that adsorption capacities and removal percentage of GM dye on LSN from wastewaters is about 80%. Co.. View More»
