The aim of this article was the fabrication of Al2O3/Pd(NO3)2/zeolite adsorbent through roll-coating technique for CO gas adsorption. Transmission electron microscopy (TEM), field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and energy-dispersive x-ray spectroscopy (EDX) were performed to investigate the morphological, structural, and elemental properties of Al2O3/Pd(NO3)2/zeolite adsorbent. A continuous gas analyzer KIMO KIGAZ 210 was applied for testing CO gas adsorption on as-present adsorbent in an experimental set-up. The calculated amounts of adsorption capacity at equilibrium time was 111.16 mg g-1 according to the previous published article. The Elovich, Avrami, and Fractional power kinetic models were studied for this adsorbent. The equal value of experimental and theoretical adsorption capacity at equilibrium time as well as the unit value of regression coefficient indicate that Avrami kinetic model was a suitable model to describe Co removal through Al2O3/Pd(NO3)2/zeolite adsorbent.

Dip Coating Technique

The sol-gel method provides a wide variety of applications in the medical field. One of these applications is the formation of coatings on the metal implants. The coatings containing specific additive can enhance or improve the existing surface properties of the substrate. In this work, titania sol-gel coatings were doped with two forms of silver (AgNO3, Ag3PO4) and synthetic hydroxyapatite and applied on the titanium samples by dip-coating technique. After drying and slow firing, all coatings were characterized with scanning electron microscopy. Thin coatings were successfully prepared with excellent adhesion to the substrate (measured by ASTM D 3359-2), despite cracks. Coatings containing silver and hydroxyapatite demonstrated a 100% antibacterial effect against Escherichia coli after 24 h. The bioactivity of the coatings containing hydroxyapatite tested in modified simulated body fluid under static-dynamic conditions was confirmed by bone-like hydroxyapatite precipitation. To better understand the interaction of the coatings with simulated body fluid (SBF), changes of Ca2+ and (PO4)3− ions concentrations and pH values were studied.
