“…An ultrasonic-assisted chemical co-precipitation technique was applied for the preparation of Fe 3 O 4 NPs for the composites as per the method described by Adlnasab et al 19 Solutions of FeCl 2 and FeCl 3 were prepared separately and mixed in a molar ratio of 2 : 1. After continuous magnetic stirring (1 h, 80 1C), ammonia was drop-wise added and the solution was maintained at 90 1C.…”

“…When some significant factors intervene in the optimization, the response surface methodology (RSM) is used. Among all RSM designs, Box–Behnken design requires little experience to optimize a four‐factor process; it is used to avoid experiments carried out under extreme conditions (Adlnasab, Shekari, & Maghsodi, 2019; Opris et al, 2017).…”

The aim of this work was to optimize the photocatalytic degradation of rhodamine B (RhB) using a four-factor Box-Behnken experimental design, and the study was carried out under artificial irradiation (24-W UV lamp) using ZnO in suspension. The Box-Behnken model has been validated with an error less than 5%. A total (100%) RhB removal and COD abatement rates were reached under optimal conditions of treatment time, ZnO dose, and stirring speed at different concentrations of dye. The study of the effect of irradiation type (solar and UV lamp) on the degradation of RhB showed that solar irradiation gave a better rate of degradation with complete discoloration after 2 hr. The study of RhB degradation mechanism indicates that O •− 2 were the main active species for the degradation of this pollutant. The comparison between the degradation of RhB alone and RhB prepared with varnish (as it is usually used in industry) revealed that degradation of RhB alone is faster comparing than that of RhB/varnish mixture. The results showed that the biodegradability was improved after a contact time of 60 min with a BOD 5 /COD ratio increasing from 0.23 to 0.90. © 2020 Water Environment Federation • Practitioner points • Optimization of the photocatalytic degradation of rhodamine B using a four-factor Box-Behnken experimental design. • Investigation of dye mineralization. • The degradation mechanism of rhodamine. • Biodegradability assessment based on the BOD 5 /COD ratio.

“…Moreover, a strong enhancement of the response can be observed when decreasing pH at 3A, which increase slightly at 5A. The presumed reason is that the increase of current intensity during electrooxidation enhances active chlorine generation that destroys more rapidly the conjugated chromophore system of MO, which eventually led to a greater color removal rate 23 . However, the removal rate did not increase as expected with further increase in the current density.…”

“…It's an independent, rotatable second-order design and requires fewer runs than the other design methods. It has been applied for optimization of several processes 23,24 . In the present work, a Box-Behnken experimental design has been chosen to optimize several experimental parameters (current intensity, initial pH and electrolysis time) that have significant effects on color removal efficiency of azo dye Methyl Orange (MO) by EO.…”

Degradation of textile azo dye solutions containing Methyl Orange by anodic oxidation using an electrochemical reactor was studied. The combined effect of independent parameters (current intensity, initial pH and electrolysis time) on color removal efficiency was investigated and optimized using response surface methodology. A Box-Behnken design was successfully employed for experimental design. The obtained quadratic model was statistically tested using analysis of variance (ANOVA). Results showed that the optimal operating conditions to achieve 98.51% efficiency for color removal were current intensity = 4.6 A, initial pH= 4 and electrolysis time = 65 min, at a dye concentration and temperature of 50 mg/L and 25 Â°C, respectively.
