Abstract The aluminium (Al) can cause health problems to human being at overdose. black tea is among the most common beverages in world but may contain higher amount of Al. This study was conducted determine Al content produced Rize, Tabzon and Giresun/ Turkey transferred into infusions. Tea infusions were prepared for 15, 30, 45 60 min determined using inductively coupled plasma optical emissi...

A novel chitosan-based chelating resin modified with tris(2-aminoethyl)amine moiety (CCTS-TAA) was synthesized, and its characteristics in the collection/concentration of mercury was examined. The synthesized resin showed good adsorption toward mercury in a wide pH range, and the adsorbed mercury can be easily eluted by using 2M HNO(3) without any addition of complexing agent. The resin was the...

This paper investigates different types of coastal sands: sands from El Oualidia, Sidi Moussa, Jorf Lasfar, Ouled Ghadbane, Moulay Abdellah Amghar, and Bouzid in the Doukkala region (Morocco). The main objective this is selection best sand for use construction. were subjected to physicochemical characterization by analytical techniques: analyses particle size, apparent density, absolute water a...

Since its existent, the principle of the chromatomembrane mass transfer has been used in flow injection analysis mainly for determining of inorganic and organic substances in environmental samples and coupled with several detection systems such as photometry, voltammetry, inductively coupled plasma-atomic emission spectroscopy, gas chromatography, ion chromatography, and high performance liquid...

In this work, a method to determine Pb(II) ions in model water is presented; the based on fluorescence emission of silver nanoclusters (AgNCs) colloidal solution, which sensitive lead ions. The presence causes photoemission enhancement AgNCs solution dependent pollutant concentration. functional dependence logarithmic range from 2.5 40 µM, and through linearization calibration points, linear fu...

High-entropy sulfides (HESs) containing 5 equiatomic transition metals (M), with different M:S ratios, are prepared by a facile one-step mechanochemical approach. Two new types of single-phase HESs pyrite (Pa-3) and orthorhombic (Pnma) structures obtained demonstrate homogeneously mixed solid solution. The straightforward synthesis method can easily tune the desired metal to sulfur ratio for st...

As a novel performance, methanol gas conversion to dimethoxymethane (DMM) in one-step based on Fe-Mo-O (iron molybdate mixed oxides) catalysts with high surface area fabricated by metal organic frameworks (MOFs) precursors was improved. For this approach, at first, Fe(III) precursors (iron (III) 1,3,5-benzenetricarboxylate (MIL-100 (Fe) and iron terephthalate (MOF-...

The use of calcium silicate coatings has extensively increased due to properties such as biocompatibility and proper bioactivity response. present study was aimed investigate the wollastonite-hydroxyapatite (WS-HA) bio-nanocomposite for treatment orthopedic implant by adding magnetic nanoparticles (MNPs) single-walled carbon nanotubes (SWCNTs) matrix. coated on Mg substrate 40 min at V using el...
