The removal of strontium(II) and neodymium(III) from their aqueous solutions on chrysotile nanotubes

In this research, chrysotile nanotubes (ChNTs) were synthesized by the hydrothermal method. Synthetic ChNTs were characterized using XRD, SEM, TEM and N-2 adsorption-desorption. Adsorption technique was applied for removal of Sr(H) 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(H) and 47.44 mg.g(-1) for Nd(III) at 298 +/- 1 K. FTIR and XPS techniques were employed to investigate possible adsorption mechanism.
