Biology – Micro- and Molecular Biology.

The release of colored substance even at very low concentrations can cause serious damage because these dyes prevent sunlight penetration and then have a pejorative effect on photosynthesis process in aquatic ecosystem [3,4]. Engineering – Industrial Engineering and Management.

L27 Orthogonal Array

Each new text counts as one lot! However, post adsorption recovery of nano-adsorbents for reuse and regeneration involves centrifugation which implicates extra cost and time. Reactive Orange 12 RO 12 is an anionic dye and is very frequently used for coloring silk, wool, leather, jute and cotton and can be applied as biological staining, dermatology, veterinary medicine, and green ink manufacture [5]. Thus the composite has been conveniently recovered from the aqueous solution by an external magnetic field and could have potential application as a magnetic nano-scale adsorbent to remove pollutants.

Taguchi design of experiments Taguchi design of experiment was proposed by Genichi Taguchi [32], which simplified the statistical design efforts by using orthogonal array.

The Magnetic Levitation Train: The higher adsorption capacity at higher dye concentration at a fixed adsorbent dose is because of stronger interaction between dye molecule and adsorbent at higher ionic concentration of RO 12 [43].

Magnet Schools and their Impact on public education in North Carolina. Unsaturated active sites of adsorbent surface krthogonal higher dose and overlapping in arrayy surface area may reduce the total effective surface area which in turn decreases the adsorption capacity at higher dose [21]. In this adsorption study, the effect of each process variables were studied in details and the adsorption orthogojal was optimized by Taguchi L27 orthogonal array design for maximizing the RO 12 dye removal efficiency.

Furthermore, several conventional kinetics, isotherms, and thermodynamic analysis were also performed to understand the adsorption mechanism. Azo dyes are the most widely used synthetic dyes in industry and problems associated with most of the azo dyes are their stability, recalcitrant to microbial biodegradation, colorant and even potentially carcinogenic and toxic to human being [1,2].

On account of above stated hazards of toxic dyes, the environmental scientists have shown remarkable interest to design and develop innovative approaches for their efficient and quantitative elimination by simple, economical and fast techniques. The main objective of this Taguchi based optimization was to define the optimum experimental conditions for maximum RO 12 dye removal efficiency. A Technology ahead of Its Time?

Arrwy addition to develop novel adsorbents with high functionality towards toxic dyes, several mathematical models can be accomplished in such adsorption processes for determination of relevance and evaluation of statistical significance of various process variables and their simultaneous interaction [30].

India and used for preparing the aqueous solutions of different dye concentration for batch adsorption study. An environmentally benign technique with efficient removal efficiency in a short time with minimum requirements of chemicals is greatly recommended. Taguchi design of experiment was proposed by Genichi Taguchi [32], which simplified the statistical design efforts by using orthogonal array.

The contribution of the experimental parameters were calculated as Our newsletter keeps you up to date with all new papers in your subjects.

Effects of various experimental parameters such as initial solution pH, adsorbent dose, initial RO orthogohal dye concentrations, and contact time were systematically explored in this study. Isolation and molecular characterization of dye tolerant bacteria f The layout of the orthogonal array considering five operational variables, each taken at three levels is shown in Table 2. Separation of magnetic nanoscale materials using external magnetic field for easy collection from wastewater offers a solution to this problem [26].

The contribution of experimental parameters onto dye removal efficiency was determined from Taguchi design of experiment.

Taguchi optimization The main objective of this Taguchi based optimization was to define the optimum experimental conditions for maximum RO 12 dye removal efficiency. Moreover, magnetic separation technology could be cheaper than the conventional separation methods.
