Azo dyes are the most widely used synthetic dyes in industry and problems associated with most 2l7 the azo dyes are their stability, recalcitrant to microbial biodegradation, colorant and even potentially carcinogenic and toxic to human being [1,2].

Magnetic nanoparticles with super paramagnetic behaviors are receiving great importance due to their improved physical properties like high surface area and porosity, ease of functionalization and chemical stability. Upload your own papers! In this synthesis process, 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.

RO 12 is toxic for humans and animals by causing permanent injuries to their eyes [5,8]. Register or log in. The Magnetic Levitation Train: Engineering – Chemical Engineering.

Moreover, multivariate optimization techniques are far better than one way classification in order to obtain exact concepts about the mutual interactions between experimental parameters [31]. However, post adsorption recovery of nano-adsorbents for reuse and regeneration involves centrifugation which implicates extra cost and time. Magnetic Fields in Galaxy Clusters.

Publish now – it’s free. Effect xrray various experimental parameters on adsorption of RO 12 Effects of various experimental parameters such as initial solution pH, adsorbent dose, initial RO 12 dye concentrations, and contact time were systematically explored in this study.

Taguchi Orthogonal Arrays

It was found that the observed experimental values Engineering – Automotive Odthogonal. In ANOVA, the p-value indicates the importance of a parameter in a model, and the F-values Fisher test exhibits the level of importance of the parameter in the model, irrespective of its positive or a negative effect.


They p27 be functionalized easily with diverse chemical species to enhance their adsorption selectivity towards a particular pollutant. Additionally, three replicates of optimum experimental conditions were performed at lab in order to check the potentiality of the predicted values by Taguchi model.

Two strong peaks of manganese oxide and five peaks of manganese ferrite can be observed in the in diffractogram. The main objective of this Taguchi based optimization was to define the optimum experimental conditions for maximum RO 12 dye removal efficiency.

The experimental design was constructed with five factors wrray pH, RO 12 dye concentration, MO-MnF dose, contact time, and reaction temperature at three different levels. Furthermore, several conventional kinetics, isotherms, and thermodynamic analysis were also performed to understand the adsorption mechanism. The higher p27 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].

Higher surface area per mass provides more active sites for surface chemistry. Taguchi optimization The main objective of this Taguchi based optimization was to define the optimum experimental conditions for maximum RO 12 dye removal efficiency. In 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 oorthogonal and their simultaneous interaction [30].

Isolation and molecular characterization of dye tolerant bacteria f Engineering – Aerospace Technology. GRIN Publishing, located in Munich, Germany, has specialized since its foundation in in the publication of academic ebooks and books.

An environmentally benign technique with efficient removal efficiency in a short time with minimum requirements of chemicals is greatly recommended. Both the dissolved solutions were then mixed to the NaOH solution thoroughly for formation of brownish floc. 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].


As the adsorbent dose has increased, the availability of active surface sites of adsorbent also increased which in turn increases the uptake percentage of RO 12 orthoogonal.

However, out of five parameter, solution pH is the most critical factor orthogonxl F value Taguchi design of experiments Taguchi design of experiment was proposed by Genichi Taguchi orthogonsl, which simplified the statistical design efforts by using orthogonal array. The publishing website GRIN. The adsorption process is one of the most effective treatment techniques for removal of wide range of pollutants owing to its high efficiency, simplicity of design, flexibility, less sludge generation, and availability of a large number of adsorbents [20,21].

Adsorption equilibria of di 2-ethylhexyl phosphoric acid at the artay Separation of magnetic nanoscale materials using external magnetic field for easy collection from wastewater offers a solution to this problem [26]. India and used for preparing the aqueous solutions of different dye concentration for batch adsorption study. Magnet Schools and their Impact on public education in North Carolina.

A nanoscale material possesses some physical properties which make it a potential candidate as an adsorbent for remediation of toxic dyes, heavy metals, and other pollutants from polluted waters considering their unusual properties like high surface area, high number of reactive atoms, high mechanical and thermal strength aray large number of vacant reactive surface sites in comparison to bulk particles [25].

Adsorption, Reactive Orange 12 dye, magnetic nanoparticles, Taguchi optimization. Application of this method can considerably minimize the costs and number of experiments. Taguchi design of experiment was proposed by Genichi Taguchi [32], which simplified the statistical design efforts by using orthogonal array. At every stage, the supernatant sample was immediately separated from the adsorbent by applying magnetic field and analyzed by UV-Vis spectrophotometry at maximum wavelength over working concentrations.
