The Removal of Strontium(II) and Neodymium(III) from their Aqueous Solutions on Chrysotile Nanotubes

Abstract:

In this research, chrysotile nanotubes (ChNTs) were synthesized by the hydrothermal method. Synthetic ChNTs were characterized using XRD, SEM, TEM and N₂ adsorption-desorption. Adsorption technique was applied for removal of Sr (II) and Nd (III) from aqueous solution by using ChNTs. The process had been investigated as a function of pH and temperature. The experimental data were analyzed using equilibrium isotherm models. The adsorption isotherms are fitted well by Langmuir model, having a maximum adsorption capacities of 102.56 mg·g^-1 for Sr (II) and 47.44 mg·g^-1 for Nd (III) at 298 ± 1 K. FTIR and XPS techniques were employed to investigate possible adsorption mechanism.
