Among the eight phytochemicals (dihydrocarveol, sinapic acid, vanillic acid, ethylgallate, myrtenol, transcarveol, p-methoxycinnamic acid, and isoferulic acid) we tested, p-methoxycinnamic acid (p-MCA) [10 μM] showed the most potent in vitro growth inhibition on human colon adenocarcinoma (HCT-...

A LC-MS/MS method for synephrine as a biomarker for orange honey authenticity was developed and validated. The sample was extracted with 5% TCA and cleaned up with Florisil providing 83.7% recoveries. Ions transitions for quantification and identification were 168 → 135.0 and 168 → 107.0, resp...

Electro-peroxone is a novel advanced oxidation process that surpasses ozonation or peroxone because of its advantages. In this technology, combining ozone and hydrogen peroxide generated electrochemically leads to the production of hydroxyl radicals, which are the strongest oxidizing agents. In ...

This paper reports the results of a study on the surface fluorinated titanium dioxide Wackherr’s “Oxyde de titane standard”, which shows very interesting photocatalytic activity. Characterization of FTiO2 Wackherr reveals that FTiO2 has smaller size compared to TiO2 Wackherr. The effect of fl...

A simple and convenient method for preparing a porous bio-absorbent for treating reactive dyeing effluents was developed. Chitosan adsorbent reinforced with citric acid modified β-cyclodextrin (CA-CD) was prepared via room temperature amidation followed by freeze-drying. Using reactive blue 49 ...

Biological, aerobic degradation of an azo dye and of the resultant, recalcitrant, aromatic amines in a constructed wetland (CW) was demonstrated for the first time. A vertical-flow CW, planted with Phragmites sp. was fed with 127 mg l−1 of acid orange 7 (AO7) at hydraulic loads of 28, 40, 53 and...

The interactions between human hemoglobin and orange I (or orange II) were investigated by UV/vis absorption, circular dichroism, fluorescence spectra techniques, and molecular modeling method. Orange I and orange II effectively quenched the intrinsic fluorescence of human hemoglobin by static q...

Batch adsorption experiments were carried out for the removal of procion orange from its aqueous solution using coir pith carbon. This study examines adsorption kinetic parameters on coir pith carbon. The effect of process parameters like contact time, concentration of dye, temperature and pH on...

A series of Ag–ZnO/CNT nanophotocatalysts with different multiwall carbon nanotubes loadings were prepared by precipitation–decomposition method. The samples properties were well-characterized by XRD, FESEM, EDX, BET, FTIR and DRS measurements. The results indicated that the loading of multiwa...

The purpose of this paper is to encapsulate aqueous dispersion of nanoscale C.I. Pigment Yellow 12 (PY12) with styrene-butyl acrylate resin via mini-emulsion polymerization, the PY12 dispersion was prepared through ball milling in the presence of dispersing agent. Comprehensive analyses were per...

Three sets of polyfluorenes grafting one/two orange emissive groups on central or terminal fluorene unit have been synthesized successfully through the catalyst-transfer polymerization. The molecular weights linearly increase with increase in the feed ratios of [monomer]/[catalyst] in a certain ...

Both the composition and the intake of antioxidants (anthocyanins, ascorbic acid and hydroxycinnamic acids) were reported for all blood oranges including the single cultivars (Moro, Tarocco and Sanguinello) and industrially produced juices. The mean values of the studied bioactive compounds in t...

The bulk presence of methyl orange is contributed by anthropogenic sources which poses substantial threat to health and the environment. Locally isolated Rhodococcus strains were used as alternatives to develop greener and cost effective methyl orange removal technology. Rhodococcus strain UCC 0...

The photocatalytic degradation of a model azo dye acid orange 7 (AO7) by Fe3+-doped TiO2 nanocatalyst has been studied under UV, Visible (λ >400 nm) and solar light irradiation. The role of hydrogen peroxide to enhance the catalyst’s efficiency was examined. The reaction pathway of complete mi...

The use of low-cost, easy obtained, high efficiency and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. This study investigates the potential use of activated carbon prepared from orange peel for the removal...

Co-stimulatory molecules (CD83, CD80 and CD86), belong to immunoglobulin superfamily, are type I membrane glycoprotein, which express on antigen presenting cells and provide the second signal for the activation of T lymphocytes. In the present study, we cloned the grouper's CD83 (675 bp) an...

Complete processing of biomass feedstock is critical to the success of integrated biorefineries. In this work, a first optimization study regarding orange peel waste (OPW) acetone extraction, and acid and enzymatic hydrolysis was developed via Taguchi design of experiments, leading to high yield...

We report an investigation of the title process. The corresponding process variables such as the concentration of surfactant, temperature, initial concentration of dye have been optimized by the response surface methodology (RSM). A 23 full factorial design was employed to analyze the individual...

Sanguinello and Tarocco (Citrus sinensis [L.] Osbeck) are the most common and widespread blood oranges varieties in the Mediterranean climate area. Its interest is increasing mainly due to nutritional and organoleptic properties. In this work, three blood orange varieties cultivated in Spain (Sa...
