An aqueous C.I. Acid Red 2 solution was decolorized by electrolysis using iron as anode. The decolorization mechanism was investigated through experimental observations on the electrochemical behavior of C.I. Acid Red 2 on Pt rotating disk electrode, UV–visible spectra of the solution and IR sp...

Ion exchange technology has been applied to adjust the pH of red wine and improve its tartaric and oxidative stability. Ion exchange appears to be a useful technique to achieve these objectives. Regarding the effect of ion exchange on organoleptic characteristics and the quality of the obtained ...

The interaction between bovine haemoglobin and C.I. Solvent Red 24 was investigated by UV/vis absorption, fluorescence, resonance light-scattering spectra, synchronous fluorescence as well as three-dimensional fluorescence spectra techniques at pH 7.4. The dye effectively quenched the intrinsic ...

In this study, the interaction between C.I. Acid Orange 7 (AO7) and human serum albumin (HSA) was firstly investigated using nuclear magnetic resonance (NMR) spectroscopy in combination with fluorescence quenching spectroscopy, three-dimensional fluorescence spectroscopy, UV–vis absorption spec...

Acid red 88 dye degradation efficiency of newly isolated filamentous fungus, Achaetomium strumarium were investigated. Molecular studies of 23S rRNA sequence data confirmed the phylogenetic clade relationship of the isolate with members of the same genus, Achaetomium. Achaetomium strumarium deco...

The mechanism of interaction between C.I. Acid Red 2 and human serum albumin was studied using different spectroscopic methods. The binding constants for the formation of a complex between the dye and albumin were 2.557, 2.461 and 2.383 × 105 M−1 at 298, 304 and 310 K, respectively. The associa...

Native, acid and alkali pretreated dried Potamogeton crispus (P. crispus) was used for adsorption of Reactive Red 198 from aqueous solution. Effects of physicochemical environment on adsorption were investigated. The surface charge of the native, acid and alkali treated biomass were determined t...

BackgroundEpidemiological evidence suggests that the increased intake of omega-3 polyunsaturated fatty acids can prevent atherosclerosis-related cardiovascular diseases. Recently, serum eicosapentaenoic acid to arachidonic acid (EPA/AA) ratio has been reported to be a predictive marker of cardio...

In this research, the degradation of Acid Red 274 (AR 274) was investigated under subcritical water conditions using H2O2, which led to the oxidative degradation of Acid Red 274 up to its 80% of mineralization. The Box–Behnken design matrix and response surface methodology (RSM) were applied in...

Treatment of F344 rats and B6C3F1 mice with C.I. Pigment Red 3 in the diet (10, 5.0, 2.5, 1.25, 0.6 or 0.3%) for 14 and 90 days resulted in haematological alterations consistent with haemolytic anaemia. Rats appeared to be more sensitive than mice to the haematological effects. Histological lesi...

The potential genotoxic activity of carminic acid (CAS no. 1260-17-9; EINECS no. 215-023-3; C.I. no. 75410), a component of natural red colouring products (cochineal: CAS no. 1343-78-8; EINECS no. 215-680-6; C.I. no. 75470), used in food, cosmetics and drugs, has been evaluated by means of a ser...

Decolorization of azo reactive dyes by ozone has been described by several authors. However, the efficiency of ozonation and the by-products produced by dye additives/impurities such as synthetic precursors, by-products, salts and dispersing agents in commercial azo dyes during the oxidative tre...

The degradation of C.I. Acid Red 73 (AR 73) was investigated by advanced Fenton process based on zero-valent iron and hydrogen peroxide. The effect of zero-valent iron dosage, hydrogen peroxide concentration, initial pH, initial dye concentration, mixing rate and temperature on the degradation o...
