This study proves that the new developed zinc-doped hydroxyapatite (ZnHAp) colloids by an adapted sol-gel method can be widely used in pharmaceutical, medical, and environmental industries. ZnHAp nanoparticles were stabilized aqueous solution, their colloidal dispersions have been characterized different techniques. Scanning Electron Microscopy (SEM) was to get information on morphology composition of investigated samples. Energy-dispersive X-ray spectroscopy (EDX) analysis confirmed...
This article gives an overview of the preparation, applications, and limits organoclay materials in environment field. Organoclays are obtained by combination clay minerals surfactants (quaternary alkyl ammonium salts others) appropriate candidates for adsorption organic contaminants such as pesticides, herbicides, pharmaceuticals that more found water resource despite wastewater treatments. review focuses on novel preparation methods based use nonconventional nonionic interest these hybrid...
We present a detailed investigation of the molecular structure montmorillonite, an aluminosilicate clay with important applications in materials sciences, such as for catalysis, drug delivery, or waste barrier. Solid-state 29Si, 27Al, 25Mg, and 1H nuclear magnetic resonance (NMR) measurements combined density functional theory (DFT) calculations provide comprehensive picture local composition synthetic its naturally occurring analogue. A revised is proposed based on NMR results that allow...
The aim of the current research work was to study physicochemical and biological properties synthesized zinc doped hydroxyapatite (ZnHAp) nanoparticles with Zn concentrations<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:msub><mml:mrow><mml:mi>x</mml:mi></mml:mrow><mml:mrow><mml:mtext>Zn</mml:mtext></mml:mrow></mml:msub><mml:mo>=</mml:mo><mml:mn fontstyle="italic">0</mml:mn></mml:math>(HAp),<mml:math...
A lignin sample was extracted from Eucalyptus grandis sawdust, by the Klason method, and used as adsorbent for removal of methylene blue (MB) aqueous solutions. By using a set complementary analytical tools, appeared to be constituted oxygenated functional groups aromatic moieties, while showing specific surface area 20 m2 g−1 polydisperse particles. Different experimental conditions with various solid liquid ratio, pH, well other external parameters were investigated MB sample. The...
Contamination of water with heavy metals such as lead is a major worldwide problem because they affect the physiological functions living organisms, cause cancer, and damage immune system. Hydroxyapatite, (Ca5(PO4)3OH) considered one most effective materials for removing from contaminated water. The hydroxyapatite nanopowders (N-HAp) obtained by co-precipitation method were used in this research to determine effectiveness ions solutions. In study, we have investigated structure morphology...
Silver doped hydroxyapatite [AgHAp, Ca10−xAg(PO4)6(OH)2], due to its antimicrobial properties, is an advantageous material be used for various coatings. The AgHAp thin films with xAg = 0.05 and 0.1 were achieved using the spin-coating method. resulting samples examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force (AFM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, photoelectron (XPS). XRD analysis revealed that particles of both are...
A nonionic surfactant, the tri-ethylene glycol mono n-decyl ether (C10E3), characterized by its lamellar phase state, was introduced in interlayer of a Na-montmorillonite clay at several concentrations. The synthesized organoclays were Small Angle X-Ray Scattering conjunction with Fourier Transform Infrared spectroscopy, and adsorption isotherms. Experiments showed that bilayer C10E3 intercalated into space naturally exchanged Na-montmorillonite, resulting aggregation lyotropic liquid...
A Na-smectite clay mineral (Na-Mt) was exchanged with various amounts of benzyldimethyltetradecyl ammonium chloride cationic surfactant (BDTAC) up to four times the cation exchange capacity (CEC). The adsorption properties these organoclays as well a coupled micelle/organoclay process were evaluated remove an anionic pharmaceutical product, diclofenac (DCF), recognized recalcitrant compound for conventional water treatments and be poorly adsorbed onto untreated mineral. DCF affinity appears...
A Na-smectite clay mineral (Na-Mt) was exchanged with two concentrations of benzyldimethyltetradecyl ammonium chloride cationic surfactant up to one time the cation exchange capacity. Nonionic organoclay prepared polyoxyethylene (20) oleyl ether (Brij-O20) nonionic at concentration. The resulting organoclays displayed lateral layer organization surfactants within their interlayer space.. adsorption properties these and starting raw were evaluated for three extensively used antibiotic...
