In this study, the improvement of the Cu (II) ion sorption performance of nano- -silica and nano-alumina particles was investigated by the impregnation of 1-ethyl-3-methyl imidazolium bis(trifluorosulfonyl)imide [Emim+Tf2N-] ionic liquid (IL). The immobilization process of IL was achieved via the ultrasound-assisted physical impregnation method. The structural and morphological characterization of the adsorbents was investigated by Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM) analysis. The thermal stability of the ionic liquid impregnated nanoparticles was also characterized by thermogravimetric analysis (TGA). The effect of the loading ratio (LR) and the sonication time (tD) on the sorption performance of the modified nanoparticles were investigated. The efficient adsorption was obtained by using the particles containing IL at the loading ratio (mL-IL/g-part) of 0.5:1. And the optimum value for the sonication time was chosen as 15 min in ethanol media. The sorption performances of the nanoparticles were enhanced by impregnation up to 92% in the aqueous media. The sorption equilibrium behaviour of the modified nanoparticles was also evaluated. The experimental data indicated that the equilibrium behaviour was in line with the Langmuir sorption isotherms.

Anionic Framework

A new cadmium dicyanamide complex, poly[tetramethylphosphonium [μ-chlorido-di-μ-dicyanamido-κ4N1:N5-cadmium(II)]], [(CH3)4P][Cd(NCNCN)2Cl], was synthesized by the reaction of tetramethylphosphonium chloride, cadmium nitrate tetrahydrate and sodium dicyanamide in aqueous solution. In the crystal structure, each CdIIatom is octahedrally coordinated by four terminal N atoms from four anionic dicyanamide (dca) ligands and by two chloride ligands. The dicyanamide ligands play two different roles in the building up of the structure; one role results in the formation of [Cd(dca)Cl]2building blocks, while the other links the building blocks into a three-dimensional structure. The anionic framework exhibits a solvent-accessible void of 673.8 Å3, amounting to 47.44% of the total unit-cell volume. The cavities in the network are occupied by pairs of tetramethylphosphonium cations.

Adsorbent Surface

Modified pomegranate peel (MPGP) and formaldehyde modified pomegranate peel (FMPGP) were prepared and used as adsorbent for removal of Cr(VI) ions from aqueous solution using batch process. The temperature variation study of adsorption on both adsorbents revealed that the adsorption process is endothermic, from the positive values of ∆H˚. These values lie in the range of physisorption. The negative values of ∆G˚ show the adsorption is favorable and spontaneous. On the other hand, these negative values increases with increase in temperature on both adsorbents, which indicate that the adsorption is preferable at higher temperatures. ∆S˚ values showed that the process is accompanied by increase in disorder and randomness at the solid solution interface due to the reorientation of water molecules and Cr(VI) ions around the adsorbent surface. The endothermic nature of the adsorption was also confirmed from the positive values of activation energy, Ea, the low values of Ea confirm the physisorption mechanism of adsorption. The sticking probability, S*, of Cr(VI) ion on surface of both adsorbents showed that the adsorption is preferable due to low values of S*(0< S*< 1 ), but S*values are lower for FMPGP indicating that the adsorption on FMPGP is more preferable .
