Abstract
Magnetite Nanoparticles (MNPs) have become a promising material for scientific research. Among numerous technologies, MNPs seem to be one of the most convenient to environmental applications
as adsorbent. In the present study, the dye adsorption from aqueous solution, using available resources such as Crystal Violet (CV) as model colorant was used. The magnetic nanoparticles (MNPs: before and after adsorption) were characterized by FTIR, SEM and TEM techniques. These nanoparticles have a spherical shape and their diameter about 11 nm. The influence of several experimental conditions (pH, contact time, sorbent dose, concentration and temperature) as well as properties of the adsorbent materials in terms of thermodynamics, kinetics and adsorption isotherms was all investigated. Once compared with adsorption models, our results enabled us to describe this adsorption as a process being spontaneous, exothermic and
having pseudo-second order kinetics. The adsorption isotherm data were described by the Freundlich model.
