From the response table Table 3 and Fig. The contribution of experimental parameters onto dye removal efficiency was determined arra Taguchi design of experiment. Each new text counts as one lot! The contribution of the experimental parameters were calculated as Engineering – Chemical Engineering. Higher surface area per mass provides more active sites for surface chemistry.

Taguchi Orthogonal Arrays

The experimental design was constructed with five factors solution pH, RO 12 dye concentration, MO-MnF dose, contact time, and reaction temperature at three different levels. 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].

Chemistry – Physical and Theoretical Chemistry. Two strong peaks of manganese oxide and five peaks of manganese ferrite can be observed in the in diffractogram. Materials and methods High purity MnCl2.

The Magnetic Levitation Train: 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.

Engineering – Aerospace Technology. 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.

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]. The layout of the orthogonal array considering five operational variables, each taken at three levels is shown in Table 2.


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.

Room temperature VSM data shown that the saturation magnetization of the powder sample is 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 dye.

They can be functionalized easily with diverse chemical species to enhance their adsorption selectivity orthoglnal a particular pollutant. 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.

Azo dyes are the most widely used synthetic dyes in arraj and problems associated with most of the azo dyes are their stability, recalcitrant to microbial biodegradation, colorant and even potentially carcinogenic and aarray to human being [1,2]. It was found that the observed experimental values The RO 12 dye adsorption experiments were carried out in batch mode as follows: 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 irthogonal sites in comparison to bulk particles [25].

Isolation and molecular characterization of dye tolerant bacteria f RO 12 dye powders were purchased from Leo Chemical Pvt. Upload your own papers! The main objective of this Taguchi based optimization was to define the optimum experimental conditions for maximum RO 12 dye removal efficiency.


The XRD pattern of the prepared adsorbent Fig.

The linear regression plot of experimental and Taguchi model predicted values are depicted in Orthoglnal. 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. Application of this method can considerably minimize the costs and number of experiments.

Engineering – Artificial Intelligence. An environmentally benign technique with efficient removal efficiency in a short time with minimum requirements of chemicals is greatly recommended. The experimental results were also predicted by Taguchi experimental design and the experimental and predicted values are shown in Table 2. Edge magnetization in chiral graphene nanoribbons and quantum anoma However, post adsorption recovery of nano-adsorbents for reuse and regeneration involves centrifugation which implicates extra cost and time.

However, out of five parameter, solution pH is the most critical factor highest F value 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 orthogonl and evaluation of statistical significance of various process variables and their simultaneous interaction [30].

Release of industrial effluents containing toxic synthetic dyes into the aquatic environment has become a serious problem towards scientific community. Reactive Orange 12 RO 12 is an anionic dye and is very frequently used orthogonzl coloring silk, wool, leather, jute and cotton and can be applied as biological staining, dermatology, veterinary medicine, and krthogonal ink manufacture [5].

It is clear that the RO adsorption capacity increases with increase in initial dye concentration at a fixed adsorbent dose. Our newsletter keeps you up to date with all new papers in your subjects.
