“…Ion exchange with the ions from the surroundings can take place in them. The clay minerals concerned can swell because of increase of space between basal layers where absorbed ions or molecules are located [15]. The application of apatite materials for adsorption and immobilization of various pollutants is a promising technique because of their high absorptivity, ease of use and environmental friendliness [16].…”

The adsorption of methylene blue from model aqueous solutions on bentonite-like clay, hydroxyapatite, and a composite sorbent has been investigated. The kinetic and thermodynamic parameters of adsorption in the temperature range 298–333 К have been calculated. The process is found to obey Langmuir isotherm equation. It is spontaneous but slightly endothermic. The maximal sorption capacity of the composite sorbent toward methylene blue is 175.4 mg/g at 25 °С that is 1.3 times more than that for bentonite-like clay and 17.8 times more than that for hydroxyapatite. Kinetics of the process is due to the combination of external and internal diffusion and can be described better by the model of pseudo-second order reaction.

“…5 of 2017, the author made an effort to enhance the added value of ZOC to become new materials of ZrO2-montmorillonite. Montmorillonite mineral is widely found in some areas such as in Gunung Kidul district and it could be obtained by importing from Thailand with a cheaper price [2] The quality of pillarization is urgently understood in the application of ZrO2-montmorillonite as an adsorbent, catalyst and semiconductor materials so that it is very interesting as the research topic for being conducted. The new material ZrO2-montmorillonite is widely used in catalysts for several organic processes, especially oil refining (hydrotreating, hydrocracking, and catalytic), and has been widely synthesized by some authors using ZOC made in some industrial products.…”

Characterization of the pillarization process product of ZrO2-montmorillonite from Zirconium oxychloride local made of PSTA-BATAN has been done. The objective of this research is to control the quality of pillarization process product of the new material ZrO2-montmorilonite. This new material was produced from local made Zirconium oxychloride (ZOC) of PSTA-BATAN by dry process and bentonite (Na-montmorillonite) imported from Thailand by the pillarization process. During optimization the pillarization quality control would be followed by absorbance using Diffuse Reflectance Ultraviolet-Visible (UV-Vis DRS) spectroscopy and X-Ray Diffraction (XRD). While the type of functional group can be detected by Fourier Transform Infrared (FTIR) spectrophotometry, and the surface image was observed by using Transmission Electron Microscopy (TEM) and BET methods. The result gained showed that the optimum quality of ZrO2-montmorillonite was at Zr concentration of 0.2 M with the absorbance of 1.04 au by XRD and DRS. The best precursor used was ethylene glycol with a drying process in the cold conditions at the absorbance of 1.2 au. The best calcination process was at the temperature of 600 °C with the reached absorbance value of 1.3 au. The results of TEM image observation after calcination at the temperature of 600 °C were clearer and more porous than before and showed specific surface area of 105 m2/g. The interpretation results of FTIR spectra on the new material of ZrO2-montmorillonite contained the cluster of ΞSi-OH, ΞAl-OH and Si-O functional groups indicating pillar groups.
