“…At pH values above 10, the BB-41 reacted with the hydroxyl groups of the NaOH solution and formed a brown precipitate at the bottom of the beaker, thus the removal of BB-41 dye with this material was not carried out (Kooli et al, 2015). The formation of the precipitate was the result of the BB-41 decomposition in strong alkaline environments (Roulia and Vassiliadis, 2005). It was important to note that the absorption characteristics of the BB-41 were insensitive to changes in pH with λ max of 610 nm.…”

“…The application of the acid activated clays in the removal properties of basic blue-41 (BB-41) was examined from aqueous solutions. BB-41 is a basic dye, once is dissolved in water, it carries a net positive charge due to the presence of protonated amine or sulfur containing groups (Roulia and Vassiliadis, 2005). The Langmuir model was used to estimate the maximum removal capacity of the different clay minerals, the removed amounts were associated to the properties of the treated clay minerals.…”

“…Les argiles sont écologiques, pas toxiques, et peu coûteuses. L'importance chimique des minéraux argileux est due à leur structure cristalline, à leur surface élevée, à leur capacité d'échange ionique et à de bonnes propriétés de gonflement dans certains cas [7,8]. Les minéraux argileux sont importants en raison de leur grande échelle d'application dans l'industrie de fabrication de l'acide phosphorique et de la possibilité de modifier leur structure en couches par intercalation [9].…”

Abstract. Stainless steels have many properties mechanical and chemical resistances resulting from the formation of the protective layer (passive film) on their surface which prevents the metal to react with corrosive environments such as, phosphoric acid. This acid contains various impurities, including agressive agents and solid particles of gypsum, increase the risk of corrosion damage depending on the type of stainless steel used. In addition, it has been show that abrasion-corrosion causes an acceleration electrochemical process leading to a decrease in the resistance of materials. This work is to find a solution through an ecological inhibitor. That why we have been studied the effect of crude clay on corrosion behavior of Alloy 31 in polluted phosphoric acid with abrasive by electrochemical impedance spectroscopy (EIS) . The clay was characterized by X-ray fluorescence spectroscopy (FX), X-ray diffraction (DRX) and infrared spectroscopy (IR). EIS exhibited that resistance of Alloy 31 increased with increase the concentration of inhibitor.

“…Basic Blue 41(CB41) is a mono-azo-basic dye of bright blue hue; it is particularly suitable for dyeing acrylic substrates and can also be applied to some polyamide and polyester types, viscose, cotton, and wool. It is also effective as strainer for the identification of avian leukocytes and blood and bone-marrow cells [3]. This basic dye may be considered one of the most toxic substances [4].…”

A computational study of the structure of zinc fluoride surfaces AIP Conference Proceedings 1653, 020051 (2015) Abstract. Zinc oxide nano-powder was prepared using sol-gel technique to be encapsulated onto polymeric blend composed from alginate and polyvinyl alcohol to fabricate novel bio-composite beads of nano-zinc oxide. The XRD patterns of both zinc oxide nano-powder and its polymeric hybrid were crystalline in their nature. The FTIR analysis of the fabricated ZnO polymeric hybrid confirms the binding between zinc oxide and the polymeric matrix. The BET analysis demonstrated that the calculated specific surface area of the formulated ZnO beads that equal to 22.8 m 2 /g is comparatively less than that of the free ZnO nano-powdered that equivalent to 64.9 m 2 /g. The thermal stability of ZnO nano-powdered dramatically decreased with its immobilization into the polymeric alginate and PVA matrix. The formulated beads had very strong mechanical strength and they are difficult to be broken up to 1500rpm. Moreover, this hybrid beads are chemically stable at the acidic media. The formulated ZnO hybrid beads verified to be good adsorbent material for C.I basic blue 41 (CB41).
