In this work, the adsorption process of methyl orange (MO) removal by a magnetic chitosan with an Al 2 O 3 /Fe 3 O 4 core was optimized using the experimental design method in order to maximize the removal efficiency. Response surface methodology (RSM) based on central composite design (CCD) was performed to find the relationship between the effective adsorption parameters on the MO removal efficiency as the response. The statistical parameters of the derived model were acquired: R 2 = 0.9799 and F value = 47.07. Finally, non-linear optimization was carried out and values of 6.5, 0.70 g l -1 , 30 ppm, and 60 min were obtained as the optimum values for pH, adsorbent dosage, initial concentration, and contact time, respectively, while the predicted MO removal efficiency was found to be 96.8 ± 2.2% (with a 95% confidence level). This was in agreement with the experimental response of 96.5 ± 1.4%.Keywords: adsorption; optimization; chitosan; magnetic; response surface methodology ПРИМЕНА НА МЕТОДОЛОГИЈАТА НА ПОВРШИНА НА ОДГОВОР ПРИ ОПТИМИЗАЦИЈА НА АТСОРПТИВНО ОТСТРАНУВАЊЕ НА МЕТИЛ ОРАНЖ СО НАНОКОМПОЗИТ ОД МАГНЕТИЗИРАН ХИТОСАНВо ова истражување, со примена на методот на експериментален дизајн, беше оптимизиран атсорпцискиот процес на отстранување на метил оранж (МО) со магнетизиран хитозан со јадро од Al 2 O 3 /Fe 3 O 4 за да се максимизира ефикасноста на отстранувањето. Беше применета методологијата на површината на одговор (RSM) заснована на централен копмпозитен дизајн (CCD) за да се најде зависноста меѓу ефективните атсорпциски параметри за ефикасноста на отстранувањето на МО како одговор. Беа добиени статистички параметри изведени од моделот R 2 = 0,9799 и вредноста F = 47,07. На крајот, беше извршена нелинеарна оптимизадција и беа добиени следниве соодветни оптимални вредности за рН, доза на атсорбенсот, почетна концентрација и време на контакт од 6,5, 0,70 g l -1 , 30 ppm и 60 min, соодветно, додека предвидената ефикасност на отстранување изнесуваше 96,8 ± 2,2% (со 95% ниво на веродостојност) што беше во согласност со експериментално добиената вредност од 96,5 ± 1,4%.Клучни зборови: атсорпција; оптимизација; хитозан; магнетски својства; методологија на површина на одговор

“…Zeolite is characterized by many sharp peaks by XRD and they are shown in Figure 3. These peaks are clearly seen in the composite structure when compared with the literature [24]. The peaks around 11.36 ∘ , 22.47 ∘ , 30.16 ∘ , and 56.25 ∘ reveal its cubic lattice structure assigned to the planes.…”

“…Furthermore, this composite is generally considered to The intention of the present research is the synthesis and use of poly(AN-co-VP)/zeolite) composite to investigate the impact of three parameters: initial dye concentration, adsorbent mass, and contact time on the removal of the dye BG, using central composite design (CCD) which is a standard response surface methodology (RSM). RSM is the collection of statistical and mathematical tools and it was selected to explain the simultaneous effects of the parameters on the adsorption process [24][25][26].…”

In this study, a poly(acrylonitrile-co-N-vinyl pyrrolidone)/zeolite (poly(AN-co-VP)/zeolite) composite was synthesized by in situ free radical polymerization (FRP). The structural properties of the composite were analyzed by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The characterization results indicated that the composite had a homogeneous and 3-dimensional (3D) structure. The decomposition temperature and glass transition temperature (Tg) were found as 410°C and 152°C, respectively. A poly(AN-co-VP)/zeolite composite was used to investigate the adsorption of brilliant green (BG) which is a water-soluble cationic dye. The kinetics, isotherms, and thermodynamics of adsorption were examined, and results showed that equilibrium data fitted the Langmuir isotherm model, and the adsorption kinetics of BG followed pseudo-second-order model. According to the thermodynamic properties, the adsorption process was endothermic and spontaneous. Response surface methodology (RSM), which was improved by the application of the quadratic model associated with the central composite design, was employed for the optimization of the study conditions such as adsorbent mass, time, and initial dye concentration. The RSM indicated that maximum BG removal (99.91%) was achieved at the adsorbent mass of 0.20 g/50 mL, an initial BG concentration of 40.20 mg/L, and a contact time of 121.60 minutes.
