Polyéthylène téréphtalateIndex. décimale : 677.4 Textiles artificiels Résumé : The PET staple fiber manufacturing sector needs to tackle the water consumption issues for its future sustainability, as it is one of the most water demanding sectors in the textile industry. This paper describes a new spin finish oil with 2 general technical characteristics achieving the benefits of reducing water use, by suppressing the generation of foam in the fiber line as well as by easing the process of wastewater treatment. Of course, this new spin finish oil maintains the same very good performance as found in other products, in terms of fiber manufacturability and spinning mill processability.

Tannage au chromeIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The distribution of chrome in the wastewaters for chrome tanning and post tanning processes was investigated. The results indicate that the residual chrome in chrome tanning and rechroming wastewaters is the main origin of chrome in effluent. Meanwhile, a considerable amount of chrome is released from leather in almost all the post tanning processes, including washing, neutralizing, retanning with various retanning agents, dyeing, fatliquoring and acid fixation. As a result, more than 60% of the chrome added is discharged into wastewater. It is interesting that the shrinkage temperature of leather does not decrease along with the release of chrome.

SpectrophotométrieIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : A rapid, reliable and sensitive online method was proposed to determine sulfide ion in tannery effluent based on the combination of methylene blue spectrophotometry and automatic reference Flow Injection Analysis. In acidic media with Fe3+, without any process of H2S absorption or sample pre-distillation, sulfide could be determined directly by the automatic reference FIA function of an automatic metallic elements analyzer using p-aminodimethylaniline dimethylaniline (C6H4•NH2•N (CH3)2•2HCl) as colour developing reagent. Under the optimal conditions, the linear ranges of this method were 0.01 - 0.25 and 0.20 - 2.16µg/ml; the detection limit was 4.642ng/ml, and relative standard deviations were 2.5% (n = 8) for a 3 x diluted tannery effluent. Asatisfied result was achieved with the proposed method to determine the sulfide in tannery effluent, and then the range of recovery percentages was 96.0 - 104.0%.

Polyméthacrylate d'hydroxyéthyle-co-glycidyl méthacrylateIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Hydrogel membranes can swell by a high proportion of their weight and have a large surface area, and are nowadays preferred in adsorption studies. In this work, p(HEMA-GMA) poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) spherical particulated hydrogel membrane (SPM) was produced by UV photopolymerization and the synthesized membrane was coupled with iminodiacetio acid (IDA) in order to bond the Cr(III) ions in the chrome tanning process effluent. Then p(HEMA-GMA)-IDA-Cr(III) SPM was used to remove Acid Black 210 dye from the dyeing process effluent. The membrane's chrome and dye adsorption capacities were determined using a UV/Vis Spectrophotometer at wavelengths of 601nm and 435nm respectively. After the membranes were used, the discharged tanning and dye process wastewaters were examined in order to see the differences in the wastewater in terms of COD, BOD, conductivity, pH, salinity, total dissolved solids, total suspended solids, potassium, total nitrogen and chromium content. The results showed that the metal-chelated p(HEMA-GMA)-IDA SPMs chelated chrome ions between 398.47 and 619.10mg/g, and the adsorbed Acid Black 210 dye molecules were between 0.76 and 1.87mg/g. In conclusion, p(HEMA-GMA)-1DA SPM is an effective sorbent system for removing Cr(III) ions and acid dye molecules from leather discharge waters. Note de contenu : - Characterisation of nano-PHEMA-AB

StatistiqueIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Contamination of water bodies by organic substances, such as dyes, cause impacts on the environment and human health. Furthermore, the search for environmentally appropriate destinations for solid waste, such as those from agro-industries, has been intensifying, to minimize the impact of the growing generation of waste as a result of population growth. Thus, this work aimed to evaluate the use of raw peanut shells as an alternative adsorbent for the removal of Brown acid dye from synthetic leather dyeing wastewater. The peanut shells were milled and sieved. The material was characterized by Fourier Transform Infrared Spectroscopy. The parameters evaluated in the adsorption tests were pH, contact time, and mass of adsorbent material. The maximum adsorption capacity verified for the peanut shell was 7.753 mg/g and up to 93% of the dye was removed. The best adsorption conditions were at pH 2.5, 10 minutes, and adsorbent mass of 0.3 g in 50 mL of effluent. The results showed relevant removal of the Brown acid dye by the peanut shells’ adsorbent material.
