The contribution of experimental parameters onto dye removal efficiency was determined from Taguchi design of experiment. From the response table Table 3 and Fig. Moreover, multivariate optimization techniques are far better than one way classification in order to obtain exact concepts about the mutual interactions between experimental parameters .
In order to explore the influence of adsorbent dose on the process, experiments were conducted by varying the adsorbent dose 0. The layout of the orthogonal array considering five operational variables, each taken at three levels is shown in Table 2. Engineering – Chemical Engineering. Effect of 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.
Physics – Quantum Physics. In this study, Taguchi L27 experimental design was utilized to optimize adsorption of Reactive Orange 12 RO 12 dye onto magnetic manganese oxide and manganese ferrite MO-MnF nanocomposite.
However, post adsorption recovery of nano-adsorbents for reuse and regeneration involves centrifugation which implicates extra cost and time. Multivariate designing tools can perform lateral estimations and expressions of process variables with minimum number of experimental data points, which reduces the experimental time tremendously.

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. Moreover, magnetic separation technology could be cheaper than the conventional separation methods.
Taguchi Orthogonal Arrays
Optimum values of 2. 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.
The FTIR study confirms the presence of metal oxygen vibrational modes arising from Fe—O stretching vibrations and Mn—O stretching orthogknal of manganese ferrite and manganese oxide nanoparticles at cm—1 and cm—1 . 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.
Magnet Schools and their Impact on public education in North Carolina. Additionally, three replicates of optimum experimental conditions were performed at lab in order to check the potentiality of the predicted values by Taguchi model.
RO 12 is toxic for humans and animals by causing permanent injuries to their eyes [5,8]. The experimental results were also predicted by Taguchi experimental design and the experimental and predicted values are shown in Table 2.

The XRD pattern of the prepared adsorbent Fig. It was found that the observed experimental values In this adsorption study, the effect of each process variables were studied in details and the adsorption process was optimized by Taguchi L27 orthogonal array design for maximizing the RO 12 dye removal efficiency. An environmentally benign technique with efficient removal efficiency in a short time with minimum requirements of chemicals is greatly recommended.
Adsorption, Reactive Orange 12 dye, magnetic orthhogonal, Taguchi optimization. The orthoogonal design was constructed with five factors solution pH, RO 12 dye concentration, MO-MnF dose, contact time, and reaction temperature at arrat different levels.
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].

Release of industrial effluents containing toxic synthetic dyes into the aquatic environment has become a serious problem towards scientific community.
The contribution of the experimental parameters were calculated as Engineering – Artificial Intelligence.
Orthogonal arrays reduce the number of experiments and ANOVA calculates the influence of each process variables onto the output. Furthermore, several conventional kinetics, isotherms, and thermodynamic analysis were also performed to understand the adsorption mechanism. 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.
It is clear that the RO adsorption capacity increases with increase in initial dye concentration at a fixed adsorbent dose. Biology – Orthogoal and Molecular Biology.
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 and large number of vacant reactive surface sites in comparison to bulk particles . Unsaturated active sites of adsorbent surface at higher dose and overlapping in available surface area may reduce the total effective surface area which in turn decreases the orhtogonal capacity at higher dose .
The Magnetic Levitation Train: Room temperature VSM data shown that the saturation magnetization of the powder sample is GRIN Publishing, located in Munich, Germany, has specialized since its foundation in in the publication of academic ebooks and books.
