“…Accordingly, Freundlich isotherm gives more accurate results than the Langmuir isotherm for a wide variety of heterogeneous adsorption systems [33]. In agreement, the Freundlich model showed a strong linear relationship for As(III)/(V) adsorption on mixed magnetite-maghemite NPs [12], As(III) adsorption onto magnetite, cobalt ferrite, and manganese ferrite [15], and As(III) adsorption on nickel ferrite [17]. Conversely, better linear Langmuir model adjustment was observed for equilibrium adsorption of As(V) on magnetite, cobalt ferrite, and manganese ferrite [15].…”

“…Hence, the mechanism of As(III) [55] and As(V) [56] sorption on hematite was suggested to be chemically rate controlling, as the rate constant inversely decreased depending on temperature [26]. Adsorption rate from As(III) adsorption kinetics on nickel ferrite was also found dependent on temperature, but it increased proportionally with temperature [17]. However, in adsorption kinetics of cobalt ions onto nano-magnesso ferrite conducted at 298 K, adsorption rates were independent of initial solute concentrations [53].…”

“…Accordingly, adsorption is one of the most accepted methods for arsenic removal from water and it has been currently considered as an efficient and economical method for water treatment [8]. Last are statements supported by successful arsenic removal from water using iron oxide NPs such as magnetite [9][10][11], mixed magnetite/maghemite [12], hematite [13,14], manganese/cobalt ferrite [15,16], nickel ferrite [17], and magnetic composites [6,18]. Therein, efforts have been constantly done toward the functionalization of magnetic materials in order to obtain nanocomposites with an enhanced adsorption capacity of aqueous arsenic species [19][20][21][22][23][24].…”

In the present work, we analyzed the linear and nonlinear model suitabilities for adsorption data from aqueous As(III) removal by manganese ferrite nanoparticles (NPs). Hence, As(III) adsorption onto ferrite NPs was formerly analyzed by the intraparticle diffusion model (IPD). Then, adsorption kinetics was described by the pseudo-first-order (PFO), pseudosecond-order (PSO), and Elovich models, while equilibrium adsorption was fitted to the Freundlich and Langmuir isotherms. Linear and nonlinear kinetic and isotherm models were solved and compared. The nonlinear data fitting was applied through the lsqcurvefit user-defined function (Matlab ver. 7.10.0). The initial adsorption rate was influenced by intraparticle diffusion and surface or film diffusion from the arsenic bulk solution to ferrite NPs, according to the IPD model. Adsorption kinetics of As(III) on manganese ferrite NPs was better described by the PSO model, followed by the Elovich model and then the PFO model. Equilibrium adsorption data were only worthily described by the Freundlich isotherm model. While the PSO, Elovich and Freundlich linear models showed even better fit than the nonlinear models, determinant bias was depicted for the PFO and Langmuir linear models. Thus, to use nonlinear adsorption models is highly advisable, having the Matlab lsqcurvefit function been proven very useful to face such task.

The aim of the present work was to investigate thiol‐functionalized bentonite (TFB) as a novel adsorbent for the adsorption of As(III) from aqueous environments and to determine optimal adsorption conditions. The response surface methodology (RSM) was applied to analyze the most significant variables for adsorption including initial pH, temperature (°C, T), initial As(III) concentration (mgL−1, Co), adsorbent dosage (g, m) and contact time (min., t). The optimum adsorption conditions according to the RSM were found to be 5.98, 42.87 °C, 31.02 mgL−1, 0.33 g and 127.48 min for initial pH, T, Co, m and t, respectively. Under these conditions obtained by the model, the maximum percentage of As(III) adsorption and adsorption capacity were found to be 91.01% and 8.56 mgg−1, respectively. The kinetic studies showed that As(III) adsorption followed a pseudo‐second‐order kinetic model and the rate was controlled by both intraparticle and film diffusion. Experimental data were compared with linear isotherm models and it was found that the adsorption data has better fit to the Langmuir isotherm model. Furthermore, the thermodynamic studies showed that the adsorption of As(III) was endothermic, possible and natural. Based on all these conclusions, it can be said that TFB has high potential for As(III) removal from aqueous environments.
