In this research, a novel montmorillonite-based composite was applied for the removal of mercury (II) from aqueous solution. A facile one-step method was employed to produce dithizone-montmorillonite (Dz-MMT) composit. The effects of several parameters such as pH value of the solution, adsorbent...

Two new mercury (II) polymeric complexes namely, [Hg2(µ-bbit)Cl4]n (1) and [Hg(µ-bbit)(SeCN)2]n (2) [bbit =1,1-(1,4-butanediyl)bis(1,3- dihydro-3-methyl-1H-imidazole- 2-thione] have been successfully synthesized and characterized by the single crystal X-ray diffraction analysis, IR, CHNS, PXRD...

A series of new ruthenium(II) polypyridine complexes appending with thioether groups were designed, synthesized and characterized. The sensing ability of the complexes toward mercury ions were studied by electronic absorption and emission spectra, and the reaction of the complexes with mercury i...

Different mercury species have been found in the oil and gas reservoirs. Dynamic absorption of mercury (II) chloride (HgCl2) into solutions of mono-ethylene glycol (MEG) is reported in this work. It was observed that absorption of HgCl2 into MEG solutions was comparable to the absorption in pure...

This paper presents the detection of mercury (II) ions based on a novel hybrid Long Period Fiber Grating (LPFG)-Diffusive Gradient in Thin Films (DGT) sensor system. The fundamental design of the hybrid sensor combines the features of a gold nanoparticles-coated LPFG embedded within a DGT struct...

An esterification reaction was carried out between Rhodamine B and 9H-carbazole-9-ethanol and then this monomer was polymerized via electropolymerization by cyclic voltammetry technique. The structure of monomer was identified by FT-IR, UV–Vis, NMR, LC-MSMS and elemental analyses. The structure...

Solubility of solid components in supercritical carbon dioxide (SC-CO2) is very important for the design of chemical processes and development of supercritical applications. Correlations and predictive methods are currently being extended to generate solubility data. In this work, for the first ...

Uncovering the real content of tattoo inks is becoming of primary importance, due to the growing extent of tattooing practice. Prior to any consideration on possible toxicity of pigments or of other ink components (generally indicated as vehicle) it is vital to assess whether the inks compositio...

A series of Zn1-xCoxO (x = 0.01, 0.02, 0.03 and 0.04) green pigments have been synthesized by solid-state reaction. The pigment samples were characterized by X-ray diffraction, scanning electron microscope, thermal gravimetric, differential scanning calorimetry, ultraviolet–visible diffuse refl...

A high near-infrared reflective green pigment with a low cobalt content, Zn0.96Co0.04O, was prepared by solution combustion synthesis. The pigment was characterized by XRD, SEM, TG-DSC, UV–vis and CIE L*a*b*C*h* colorimetric. The resulting green pigment showed that the chromaticity performance ...

Ultra-fine particles of C.I. Pigment Green 36 were prepared using a continuous supercritical anti-solvent (SAS) apparatus employing quinoline as solvent and supercritical carbon dioxide as anti-solvent. A series of precipitation experiments were conducted at different temperatures, pressures, an...

A series of new green Cr-doped BiPO4 materials were synthesized by hydrothermal method and first used as solar heat-reflective pigments. XRD, FTIR, FE-SEM and HR-TEM analyses confirm that the phase structure was transformed from low-temperature monoclinic phase (LTMP) to hydrated hexagonal phase...

The synthetic nitroso dyestuff Acid Green 1 (hereafter AG1, C.I. 10020) and its lake (C.I. Pigment Green 12, hereafter PG12), today known under the trade name Naphthol Green B, was identified for the first time on six historical colour charts of commercial brands of artists’ paints. These compr...

Monodispersed PMMA (polymethyl methacrylate) particles were prepared via a dispersion polymerization process using methanol as the dispersive medium, azobisisobutyronitrile (AIBN) as initiator, and polyvinylpyrrolidone (PVP) as steric stabilizer. This study applied the Taguchi experimental desig...

The first synthesis of enantiomerically pure 2-azabicyclo[3.3.1]nonanes by an intramolecular radical reaction of the trichloroacetamido group bearing an (S)-N-1-phenylethyl substituent with the silyl enol ether moiety in compounds 7 is described. The procedure allows the two enantiomers of the 2...
