The importance of different polymorphic forms iron oxide nanoparticles attracted a lot attentions in various applications due to their unique electrical, optical and magnetic properties. Moreover, the excellent biocompatibility, high surface area, spherical shape, tunable nanoscale size availability synthesis route make them desirable biological pharmaceutical applications. To this aim, review, methods were discussed, also main characterization techniques used for elucidation reviewed....
In this work, the exploitation of synthesized magnesium oxide nanoparticles and MgO-bentonite nanocomposite as an effective photocatalyst has been reported. They were utilized to study their applicability for photocatalytic degradation crystal violet in wastewater. Fourier-transform infrared (FTIR) spectra, X-ray powder diffraction (XRPD), energy-dispersive spectroscopy (EDX), transmission electron microscope (TEM) used characterization. The efficiency photocatalysts CV decomposition...
The rapid progress in the use of textile fabric materials various industrial and domestic applications requires inclusion smart functions to achieve comfortable safety properties end users. However, among these is protection against harmful UV rays that cause effects human beings materials. To this end, coatings for fabrics have be incorporated into fabrics. Therefore, review, recent advances development sustainable will reviewed. Hence, precursors, synthesis routes types Furthermore, action...
Carbon paste electrode has been developed for the potentiometric determination of chlorpromazine HCl drug. This work focused on fabrication carbon ion selective drug under investigation using titration with sodium tetraphenylborate. The performance such sensor in is compared those PVC membrane, coated wire and graphite electrodes. was applied to pharmaceutical preparations. repeatability accuracy measurements performed analysis these matrices new were evaluated. influence composition,...
Abstract Herein, bentonite-chitosan nanocomposite (BT-CS nanocomposite) has been synthesized and exploited, for the first time, as a dual adsorbent removal of both an anionic (Reactive Red 195 (RR)) cationic (Crystal Violet (CV)) dyes from aqueous solution. The adsorption behavior exploited nano-adsorbent towards under investigation were scrutinized in batch experiments function several factors such contact pH value, dose, initial dye concentration, stirring rate, temperature. prepared...
Abstract A novel and environmentally friendly route was developed for production of sustainable flame retardant, antibacterial UV protective nanoparticles polymeric films nanocomposites. For the first time, dried molokhia leaves were engineered into spherical with an average size 8.5 nm via eco-friendly, one-pot solid-state ball-milling method. The proved using spectroscopic microscopic techniques. employed as efficient green materials polyvinyl alcohol (PVA) nanocomposite films. distinct...
Simple, rapid and sensitive spectrophotometric methods were developed for the determination of carbamazepine mosapride citrate drugs in pure pharmaceutical dosage forms. These are based on ion pair charge transfer complexation reactions. The first method is reaction drug with Mo(V)–thiocyanate hydrochloric acid medium followed by an extraction coloured ion-pair 1,2-dichloroethane absorbance was measured at 470 nm. second formation ion-pairs between two dyestuff reagents namely bromothymol...
Newly developed modified and<italic>in situ</italic>modified carbon paste sensors were for the determination of chlorpromazine hydrochloride (CPZHC) in pharmaceutical formulations and biological fluids (urine serum).
