Wet-white (tannage)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Fe(III)-loaded adsorbent (FLA) was prepared from waste wet-white. As a new adsorbent, its behaviour towards anionic dyes, Direct Yellow 11 (DY11) and Acid Yellow 11 (AY11), were investigated. It was found that the FLA is effective in removal of anionic dyes from aqueous solution and acidic pH favours the adsorption. The adsorption capacity of DY11 was significantly increased with an increase of temperature, whilst that of AY11 decreased, due to their difference in molecular structures. The maximum adsorption capacities of DY11 and AY11 at 323K were found to be 302.1 and 490.0 mg.g-1 respectively and the adsorption equilibrium data can be well fitted by the Langmuir model. The adsorption kinetics could be accurately described by a pseudo-second-order rate model. Investigation of column adsorption process indicated that FLA is effective in removal of AY11 from water, and the column can be regenerated by using dilute NH3 solution.

PolydiméthylsiloxaneLe polydiméthylsiloxane —[O-Si(CH3)2]n—, ou poly(diméthylsiloxane) selon la nomenclature systématique, communément appelé PDMS ou diméthicone, est un polymère organominéral de la famille des siloxanes souvent présent dans les shampoings. On l'y ajoute pour augmenter le volume des cheveux mais il peut également aller boucher les pores du cuir chevelu et rendre les cheveux gras. C'est une des raisons pour lesquelles se laver les cheveux tous les jours est très déconseillé avec un shampooing contenant des silicones.
Il existe également de l'amodiméthicone, qui est un dérivé du diméthicone.
Le polydiméthylsiloxane est un additif alimentaire (E900), utilisé comme antimoussant dans les boissons (Coca-Cola BlāK).
La chaîne de poly(diméthylsiloxane) forme également la structure de base des huiles et des caoutchoucs silicones.

PigmentsIndex. décimale : 667.9 Revêtements et enduits Résumé : The author explains how the construction industry is just one of many industries benefiting from the introduction of new cleaner lead-free yellows.
A new chemistry is a rare find. That is why Johnson Matthey is excited to be first to market with a new colour technology that presents an environmentally acceptable alternative to conventional cadmium, lead and sensitive heavy metals based colourants. Lead chromates and cadmium pigments have superb colour characteristics, but customers are being forced to look for alternatives, as environmental pressures increase.Note de contenu : - The next Solaplex range

LutéolineLa lutéoline ou lutéolol est un composé chimique de la famille des flavonoïdes, et plus spécifiquement l'une des flavones les plus communes. Elle fut isolée pour la première fois par le chimiste français Michel-Eugène Chevreul à partir de la gaude (autre nom du réséda des teinturiers, une plante utilisée autrefois pour fabriquer de la teinture jaune).

Rouge (couleur)Index. décimale : 667.3 Teinture et impression des tissus Résumé : This paper reports on the colorimetric properties of natural dyes from madder and weld plants. For both crops, a comparison is made among several individual dye compounds and the total plant extracts. Dyeing properties, colour properties and colour stability have been studied. Insight has been gained into the role of the major dye compounds present in the plant. For madder as well as for weld, the use of the total plant extract is considered to be advantageous over the use of individual dye compounds in terms of solubility, colour tone and stability towards light, and non-coloured components present in the plant extract are considered to be responsible for increasing the solubility and the stability of the dye compounds.
