“…The intensity of the bands increased with ODTMA loading, and their positions decreased from 2927 and 2855 cm −1 for OMt39 to 2919 and 2850 cm −1 for OMt137. This behavior indicated that alkyl chains adopted more ordered structure as the ODTMA loading increased 20,21 (alkyl chain conformations in the interlayer space will be further discussed in the XRD section).…”

To remove fungicide Imazalil (IMZ) (commercial formulation) from agricultural wastewater, adsorption was performed and compared among montmorillonite (Mt) and four organo-Mts (OMts), with different octadecyltrimethylammonium (ODTMA) loadings. The agglomerates size increase of OMts with respect to Mt found encourages the use of the former in agricultural wastewater treatment. Characterization of the OMts adsorbents by powder X-ray diffraction, infrared spectroscopy, and thermogravimetric analyses, indicated that ODTMA was present in the interlayer with different molecular arrangements, a diminution of the thermal stability of the OMts and an increase of ODTMA loading being observed at the same time. Zeta potential measurements showed electric surface charge reversion from negative to positive when the surfactant loading exceeded 100% of the clay cation exchange capacity (CEC). The IMZ adsorption on the raw Mt showed high pH dependence and affinity toward the fungicide, while OMts showed best IMZ adsorption capacity at high IMZ concentrations inversely related with the ODTMA loading. The characterization of IMZ−adsorbed samples indicated that for IMZ−Mt the interaction between IMZH + and the siloxane surface was electrostatic. For IMZ−OMt samples the presence of new XRD and FTIR peaks suggested different IMZ interlayer arrangements and direct interaction with the surface, respectively. Analysis of zeta potential measurements indicated synergetic effects between the ODTMA and IMZ molecules at the external surface.

“…The structure of the spinel ferrites can be described as a cubic, closely packed arrangement of oxygen atoms, and M 2 þ and Fe 3 þ ions can occupy either tetrahedral (A) or octahedral (B) sites. The sensing, magnetic and electrical properties of spinel ferrites are of academic and technical interest and are dependent on their chemical composition, cation distribution, grain size and the method of preparation [7][8][9][10][11][12].…”

Summary: A conducting polymer, polyaniline (PANI)/Ni 0.5 Zn 0.5 Fe 2 O 4 nanocomposites were synthesized by a simple and inexpensive one-step in-situ polymerization of Aniline monomer with Ni 0.5 Zn 0.5 Fe 2 O 4 nanoparticles, where Ni 0.5 Zn 0.5 Fe 2 O 4 nanoparticles were prepared via simple solution combustion method using stoichiometric composition of nickel nitrate, zinc nitrate and ferric nitrates as oxidizers and urea as a fuel. PANI/Ni 0.5 Zn 0.5 Fe 2 O 4 nanocomposites were characterized by X-ray diffraction (XRD) analysis, Fourier transform infrared (FTIR) spectroscopy, Scanning electron microscopy (SEM), Energy dispersive X-ray (EDX) spectroscopy and Thermal gravimetric-differential thermal analysis (TG-DTA). Frequency dependence of dielectric constant (e 0 ), dielectric loss tangent (tand) and a. c. conductivity (s ac ) studies have been undertaken on the PANI/Ni 0.5 Zn 0.5 Fe 2 O 4 nanocomposites in the frequency range 100 Hz-5 MHz at room temperature. Dielectric properties such as dielectric constant (e 0 ) and dielectric loss tangent (tand) are found to decrease with the increase in the frequency. Further, a. c. conductivity (s ac ) of the PANI/Ni 0.5 Zn 0.5 Fe 2 O 4 nanocomposites was found to increase with an increase in the frequency. Observed variation in the a. c. conductivity with the frequency has been understood on the basis of electron hopping model.
