Zéolites Index. décimale : 667.3 Teinture et impression des tissus Résumé : The Fenton-like oxidation of CI Reactive Red 141 was investigated over iron-containing ZSM-5 zeolites. Iron was loaded by ion exchange or through hydrothermal synthesis. The oxidation process was carried out in an aqueous solution using hydrogen peroxide as the oxidant. The catalyst prepared by ion exchange with a silicon/aluminium ratio of 42 zeolite showed the highest activity (97% decolorisation and 52% chemical oxygen demand reduction at an initial pH of 3.5) after an oxidation duration of 2 h. The chemical oxygen demand reduction increased with the increasing amount of iron loaded to the zeolite. The FeZSM-5 catalyst, prepared by hydrothermal synthesis in the presence of oxalic acid, showed very good activity in terms of mineralisation (99% of chemical oxygen demand reduction). The iron leaching was noticeably low (below the European Union directives of 2 mg dm−3) for the above-mentioned catalysts.

Stainless steel and ruthenium oxide-coated titanium electrodes were used as cathode and anode, respectively. A statistical tool of the Box–Behnken method has been used to design the experimental run and optimisation. The combined effect of the operating parameter on the efficiency of the process has been critically examined. A quadratic model for reduction of chemical oxygen demand has been developed. A maximum of 96% chemical oxygen demand removal was observed under optimum conditions. The degradation mechanism was studied by ultraviolet–visible spectrophotometer, Fourier Transform–infrared and high-performance liquid chromatography. From the present investigation, it has been observed that dyehouse effluent can be effectively treated using the novel electrochemical reactor.

A synergy factor of 6.9 for this combined method was determined. The decolorisation followed zero-order kinetics, and the rate increased with increasing zero-valent iron dose and decreasing pH and hydrogen peroxide concentration. The optimum conditions for an American Dye Manufacturers Institute decolorisation value of 1638 ADMI was found to be a pH of 3.0, an ultrasound frequency of 47 kHz, a zero-valent iron dose of 1.0 g l?1, and a hydrogen peroxide concentration of 1.03 × 10?2 m. Under these conditions, the estimated operating cost to decolorise 96% true colour was estimated to be $US 4.51 m?3. The study demonstrated that the given combined method could be applied to decolorise textile wastewaters.

Experimental study on supercritical water oxidation of CI Reactive Orange 7 dye wastewater using response surface methodology / Jie Zhang in COLORATION TECHNOLOGY, Vol. 128, N° 4 (2012)

Langues : Anglais (eng) Catégories : Colorants -- Détérioration Colorants -- Oxydation Colorants azoïques Eaux usées -- Epuration Fluides supercritiques Surfaces de réponse (statistique) Index. décimale : 667.3 Teinture et impression des tissus Résumé : Supercritical water oxidation of azo dye CI Reactive Orange 7 solution was investigated in a batch reactor. Response surface methodology was employed for the experimental design. Quadratic polynomial equations were established based on the results of the experiments. Optimisation of the process was then conducted in accordance with the simulated equations. The results show that removal of chemical oxygen demand, total organic carbon and total nitrogen can be achieved up to 99, 95 and 69%, respectively, and the predictive data were in reasonable agreement with the experimental results. It seems that response surface methodology is useful and feasible for the optimisation of CI Reactive Orange 7 dye wastewater supercritical water oxidation processing. The gas chromatography/mass spectrometry analysis results show that a large amount of 2,4-pentadienenitrile with diazo formed during the CI Reactive Orange 7 supercritical water oxidation reaction, which suggested that the azo firstly reacted to the diazo, and then converted into the final product of nitrogen.

Index. décimale : 667.3 Teinture et impression des tissus Résumé : When ferric ions are substituted for ferrous ions in Fenton’s reagent, the reactions which occur are called Fenton-like reactions. This study describes the relative efficiency of Fenton (with ferrous ions) and Fenton-like (with ferric ions) reactions for the degradation of a basic dyestuff, CI Basic Yellow 51, in aqueous solution. Comparisons were made on the basis of the observed reductions in chemical oxygen demand and visible absorption of the dye solutions at optimum reaction conditions. It was found that the Fenton process with 2.63 mm ferrous ion and 39.96 mm hydrogen peroxide at the optimum pH (3.0) eliminated 92.2% of chemical oxygen demand and 98.9% of colour in 22 min, whereas 43.2% of chemical oxygen demand and 64.6% of colour was eliminated by the Fenton-like process within the same time period, but at pH 4. The efficiency of the latter was significantly improved (to 96.6% removal of colour and 99.7% removal of chemical oxygen demand) by an increase in temperature of 35 °C (from 15 to 50 °C), while no improvements were observed in the efficiency of the Fenton process by temperature elevations.
