In this scientific research, for the first time, the removal of radioactive strontium-90 (90Sr) by γ-MnO2-AgA zeolite as a novel nanocomposite adsorbent was accomplished under different conditions such as pH, temperature, adsorbent amount and the contact time that are examined from drinking water of Ramsar city and monitored via Ultra Low-Level Liquid Scintillation Counting (LSC) technique. Pri...

mntio3-zeolite-y nanocomposites were synthesized with 5-10-20% (w/w) of mntio3 by stearic acid gel method. then, the gels were calcined at 900 °c for 4 hours and the resulted spectra were investigated at 20% (w/w) concentration. also, the presence of rhombohedral phase of mntio3 in zeolite-y matrix was confirmed by xrd, sem, edx and bet. the vsm results showed the antiferromagnetic properties f...

Magnetic zeolite/iron oxide nanocomposite was prepared by mixing zeolite synthesized from coal fly ashes with magnetite nanoparticles in suspension and was used for the removal of Reactive Orange 16 (RO16) and Indigo Carmine (IC) from aqueous solutions. The effect of various experimental parameters such as contact time, pH, adsorbent dose and temperature were investigated. The experimental data...

In this research, zeolite-TiO2 nanocomposite was prepared for degradation of dibenzothiophene as a typical aromatic organosulfur compound of transportation fuels.The synthesized TiO2 was immobilized on the surface of clinoptilolite by Solid State Dispersion (SSD) method. The nanocomposite was then characterized by XRD, FTIR, TEM and SEM techniques. Photodegradation of ...

A Ni-based ternary nanocomposite, Ni–rGO–zeolite, has been developed as an efficient and recyclable heterogeneous catalyst for on-water regioselective azide alkyne cycloaddition.

The study presented in this article investigated the removal of copper ions from aqueous solutions by a synthetic hydrogel-forming adsorbent polymer based on sodium alginate (SA) and hydroxy apatite (HA) nanoparticles. The effect of adding Zeolite on the adsorption performance of this hydrogel was also investigated, and the optimum amount of Zeolite was determined by changing its quantity. The ...

Purpose: To evaluate the mechanism of drug release of a slightly soluble drug (theophylline) from nanocomposite of zeolite (ZLT) or hydrotalcite (HTC) used as drug carrier. Methods: Nanocomposite was prepared with dispersion of either ZLT or HTC as drug carrier and theophylline (THP) as drug in drug to clay ratios of 1:2, 3:4 and 1:1. The formulations were characterized for drug release and loa...
