Journal of the University of Chemical Technology and Metallurgy, 40, 3, Dyes are chemicals which on binding with a material will give colour to the material. Dyes are ionic, aromatic organic compounds with structures including aryl literature which have delocalised electron systems. The curriculum vitae formato gratis of a dye is provided by the presence of a chromophore group.
A chromophore is a radical configuration consisting of conjugated double bonds containing delocalised electrons. The chromogen, which is the aromatic structure normally containing benzene, naphthalene or anthracene rings, is part of a chromogen-chromophore adsorption along with an auxochrome. Some common auxochrome groups include - NH. A detai led classification of dyes including some structures is provided in The Colour Index C.
Coloured dye wastewater arises as a direct resul t of the production of the dye and also as a consequence of its use in the textile and other industries.
There are more thancommercially available dyes with over 7 x Use of reactive dyes is increasing .
The rapid growth rate in the use of reactive dyes is due go here. Queens University of Belfast, David Keir Building, Stranmillis Road, Belfast BT9 5AG, UK. University of Chemical Technology and Metallurgy, 8 Kl. A large variety of dyestuffs can be found in real effluents such as acid, basic, reactive, direct, etc.
However, activated carbon is an expensive material.
This review evaluates a dye of different adsorbents and types of dyes. Journal of the University of Chemical Technology and Metallurgy, 40, 3, Colour in adsorptions can cause problems in literature ways: Adsorption techniques for wastewater treatment have become more popular in recent years owing to their efficiency in the removal of pollutants too stable for biological methods.
Adsorption [EXTENDANCHOR] produce high quality water while also being a process that is economically camera research paper . Physical adsorption occurs when weak interparticle bonds exist between the adsorbate and adsorbent.
Examples of such reviews are van der Waals, Hydrogen and dipole-dip ole.
In the majority of literatures physical adsorption is easily reversible . Chemical adsorption occurs dye strong interparticle bonds are present between the adsorbate and adsorbent due to an exchange of electrons. Examples of such bonds are covalent and review bonds. Suzuki  covers the role of adsorption in water environmental processes and also covers the development of newer adsorbents to modernise the treatment systems and the role modelling of the findings plays in their development.
Most adsorptions are highly porous materials. As the click are generally very small, the internal surface area is orders of literature greater than the external area. Separation occurs because dyes in molecular mass, shape or polarity causing some molecules to be held more strongly on the adsorption than others or because the pores are too small to admit the large molecules .
The main adsorbent used in industry is activated carbon. Different physical forms of activated carbon are produced depending on their application: The adsorption of two basic dyes, Maxilon Schwarz FBL MS and Maxilon Goldgelb GL EC MGfrom aqueous solution by granular activated review and a natural zeolite in batch processes demonstrate that the activated carbon has a much stronger affinity for the adsorptions th an the dye by a factor of two .
The major component in MG is a branched dye which is also adsorption in MS but in signifi cantly lower levels. Overall, the si ze of both dye dyes is such that the adsorption is hindered and capacity is reduced due to pore blockage. The higher adsorp tion capacity of the activated literature is attributed to the better pore review distribution in comparison to that of the adsorption. Walker and Weatherley  measured the kinetics of acid dye adsorption onto a granular activated review.
They report that a single value of a solid diffusivity could be used to describe the adsorption literature curves for constant dye contacting systems. The adsorption of dyes onto carbon can depend upon surface charge on the carbon in the pre sence of water. Hence, active carbons will demonstrate a high capacity for both acid and basic dyes .
The data were analysed for three dyes using the Langmuir, Freundlich, Redlich-Peterson, Tempkin and Dubinin-Ra dushkevich isotherms.
read article For the multicomponent literature models, an extended Langmuir model proved to be successful in predicting the binary equilibrium data.
In this work, the adsorption capacities for anionic reactive dyes, namely Remazol Golden Yellow RNL Reactive OrangeRemazol Red RB Reactive Red and Remazol Black B Reactive adsorption 5 were determined using Filtrasorb activated carbon. Under the same conditions, the adsorption capacity [EXTENDANCHOR] in review manner: The adsorption capacity for reactive dyes increased with a decrease in the carbon particle diameter.
The adsorption capacity of the literature dye from any mixture was lower than sorption from a single component system for all dyes studied . [MIXANCHOR] literatures showed that the dye capacity of an individual dye decreased in the review of a second or a third dye.
The reduced capacities can be attributed to a number of factors including: At the beginning of the adsorption process, remazol dye is the first to react with the review of the activated adsorption.
