“…After 1995, some attempts were made to prepare and use these nano-sized materials to simply remove dyes from aqueous systems. An early attempt was that of Wu and co-workers, who adsorbed several anionic dyes on nano-sized alumina-modified silica particles of different compositions (Wu et al 1997). Among nano-adsorbents, nanostructure materials such as MPSs have been found to be suitable adsorbents for the removal of dyes from wastewater (Joo et al 2009;Anbia and Salehi 2012).…”

The textile industry is a major user of dyes and hence an important source of water pollution, which poses a threat to aquatic as well as human life. Adsorption is a widely used technique for separating and removing dye from wastewater. Recently the use of mesoporous silica (MPSs) as an adsorbent in wastewater treatment has received considerable attention. MPSs are emerging as potential adsorbents because of their surface area, tunable and uniform pore structure, high pore volume, ordered pore structure, thermal and mechanical stability, and extraordinarily wide possibilities for functionalization to increase their adsorption capacity. In this paper the ability of MPSs to absorb dyes from aqueous solutions is reviewed. This article provides information on adsorption studies carried out under different operational conditions such as contact time, solution pH, temperature, agitation speed, etc. This review also summarizes and attempts to compare the equilibrium isotherm and kinetic models, and the thermodynamic studies that report the adsorption of dyes onto MPSs. The literature reviewed, indicate that SBA-MPSs have a higher adsorption capacity than MCM-MPSs and functionalized MPSs a better adsorption capacity than MPSs. It is evident from the literature that the potential of MPS based nano-sorbents being used for removing dyes from aqueous solution is very high. However, still more research work is needed on developing cost effective and more efficient MPS based nano-sorbents for use commercially.

“…Additionally, photobleaching of the fluorophore can be limited by the protective silica shells which is of special relevance for bioanalysis in physiological medium. Earlier reports on the adsorption of organic dyes at silica surfaces point to other possibilities among the immense field of silica nanocomposites (G. Wu et al, 1997). As it happens with a silica coating, several fluorophores can be encapsulated in a variety of polymers though in these cases, and depending on the type of polymer, biocompatibility issues need to be considered.…”

“…However, the high cost of activated carbon has restricted its use, particularly in developing countries. This is the reason why many investigators have studied the feasibility of using cheap, commercially available materials as removal agents for dyes (Wu et al 1997;Dai 1997;Perineau et al 1983).…”

ABSTRACT:The adsorption ability of natural clay towards the removal of basic dyes from aqueous textile solutions was investigated. The equilibrium isotherms were measured and analyzed using the Langmuir model and the experimental results compared with the theoretical data. The adsorbent exhibited considerable adsorption capacities of 567, 526, 427 and 300 mg/g towards Neutral Red, Methyl Violet, Methyl Green and Methylene Blue, respectively. Thus, the clay may be used as a cost-effective industrial adsorbent for the removal of basic dyes from industrial effluents.
