“…RSM was used to optimize and determine the optimum operating conditions for the uptake efficiency of Cu(II) and NY dye onto CS‐MMT hydrogel by Box–Behnken design model. In this model, numeric factors of biosorbent dosage (g), initial concentration (ppm), pH, and temperature (K) were investigated …”

A comprehensive feasibility study on adsorption of Cu(II) and a water‐soluble nitrazine yellow (NY) dye by chitosan‐montmorillonite (CS‐MMT) hydrogel as the biosorbent was investigated as a function of biosorbent dosage, initial concentration, pH, temperature, and the presence of salts. Box–Behnken methodology was applied to optimize the adsorption experiments. Maximum adsorption values were determined as 132.74 mg/g and 144.41 mg/g at pH = 5.0, for Cu(II) and NY dye, respectively. Equilibrium isotherms of Langmuir and Freundlich were analyzed by the non‐linear regression model. The equilibrium data were well described by Freundlich model and the adsorption process well fitted pseudo‐second order kinetics. The enthalpy change of adsorption (ΔH°) were calculated as −3.78 kJ/mol and −5.75 kJ/mol for Cu(II) and NY dye, respectively, indicating that the adsorption processes were exothermic. © 2016 Wiley Periodicals, Inc.

In this paper, metal salt doped with PANI (polyaniline composite) used as an adsorbent for the removal of azo dyes from aqueous solution assisted by solar light. The effectiveness of this process has been investigated by varying parameters such as contact time, initial concentration of dye solution, adsorbent dosage, temperature, electrical conductivity and pH. This experiment was carried out by irradiating the aqueous solution of dye containing adsorbent in solar light. Kinetic data well fitted for pseudo-second order model. Dyes loaded PANI composite was characterized by SEM technique. The adsorbent was found to be effective and economically attractive.

“…15 The RSM is comprised of the central composite design (CCD), Doehlert matrix (DM), and Box-Behnken design (BBD). 16 BBD is one class of experimental designs for the response surface methodology. They are rotatable or nearly rotatable second-order designs based on three-level incomplete factorial designs.…”

“…It can not only make an accurate statistical analysis of experimental data but also provides image analysis with continuity characteristics, as well as intuitively understands the correspondence relationship between the factors and the response; it has been widely used in several fields such as biochemistry, agriculture, chemical engineering, material, etc. [15][16][17][18][19] Before designing the experiment, the levels of the factors must be coded; they were investigated at a low level (21), intermediate level (0), and high level (1). The ranges and levels of the chemicals used in the experiment are presented in Table III.…”

The effect of water-soluble polymers (polyvinyl alcohol (PVA), polyacrylamide (PAM)) and chemical additives (silicone defoamer (SD), polycarboxylate superplasticizer (PC)), on the development of the strength of mortar was investigated using the BoxBehnken design (BBD). Quadratic equations were obtained for the correlation between dosages of chemicals and the strength of the mortar, and the order of the effectiveness of the chemicals was validated in Pareto charts with contour plots to illustrate the chemicals and their interactions on the strength enhancement of mortar. The results showed that the interaction effects of SD and PAM enhanced the strength of cement mortar for all curing times, and the rates of contribution were 16.5%, 20.1%, and 19.4%, respectively. On the basis of the performance analysis of the four additives, optimized formulations were highlighted via overlapped contour plots. Heat of hydration and scanning electron microscope (SEM) images were introduced to confirm the interaction between SD and PAM. The improvement of compressive strength attributes to the synergistic interactions between SD and PAM, including the physical interaction resulted from the doping of SD, which promoting the damage of air bubble, decreasing the porosity and increasing the compressive strength, and the chemical interaction resulted from the doping of PAM, which producing ionic compounds and forming dense structure.
