Adsorption capacity of tilemsi phosphate rock on basic dye in aqueous solution: methylene blue case
Valorization of the Malian phosphate rock as an adsorbent requires the determination of its performances in terms of kinetics and maximum adsorption capacity. The potential of Tilemsi Phosphate Rocks (TPR), to remove methylene blue (MB) from aqueous solution was evaluated in a batch. Experiments were carried out as function of contact time, initial concentration (25–200 mg/L), pH (4–12) and temperature (20-60˚C). Adsorption isotherms were modeled with the Langmuir and Freundlich isotherms. The data fitted well with the Freundlich isotherm.
