“…To investigate the simultaneous effect of parameters on the response and optimization of parameters, the response surface methodology (RSM) is a useful statistical technique by reducing the number of experiments (Aliabadi, Irani, Ismaeili, & Najafzadeh, ; Karri, Tanzifi, et al, ; Tripathy, Ramesh, Debnath, & Kumar, ). Among RSM approaches, the central composite design (CCD) (Zare‐Dorabei, Ferdowsi, Barzin, & Tadjarodi, ; Zolgharnein, Shahmoradi, & Ghasemi, ) and Box–Behnken design (BBD) (Bhowmik, Deb, Debnath, & Saha, ; Bhowmik, Debnath, & Saha, ; Deb, Kanmani, Debnath, Bhowmik, & Saha, ; Ebrahimzadeh, Behbahani, Yamini, Adlnasab, & Asgharinezhad, ) have been extensively used for optimization of adsorption process. Among these methods, CCD has better prediction compared with BBD method (Zolgharnein et al, ).…”

The removal of heavy metal ions and organic materials from wastewater due to their toxicity is necessary. In the present study, the titanium dioxide/zinc oxide (TiO2/ZnO) nanocomposite has been coated on the sewage sludge carbon (SSC) surface and its application was investigated for the adsorption of Ni(II), Cu(II), and chemical oxygen demands (COD) reduction from aqueous solutions and industrial wastewaters in Eshtehard, Iran. The effect of adsorption parameters in a single system such as TiO2/ZnO ratio, TiO2/ZnO concentration, pH, adsorbent dosage, contact time, ionic strength, temperature, and initial concentrations of Ni(II), Cu(II), and COD was investigated on the adsorption capacity of synthesized SSC/TiO2/ZnO adsorbent. The pseudo‐second order and Redlich–Peterson isotherm models were best described the kinetic and equilibrium data of Ni(II), Cu(II), and COD sorption. The maximum monolayer sorption capacities of Ni(II), Cu(II), and COD were found to be 62.3, 75.1, and 1,120.3 mg/g, respectively. The central composite design was used to investigate the interaction effects of pH and initial concentrations of Ni(II), Cu(II), and COD on the simultaneous removal of Ni(II), Cu(II), and COD from aqueous solutions in a ternary system. The potential of synthesized SSC/TiO2/ZnO adsorbent was investigated for Ni(II), Cu(II), and COD adsorption from industrial wastewaters of Iran. Practitioner points The novel sewage sludge carbon/TiO2/ZnO adsorbent was synthesized. Adsorption of Ni(II), Cu(II), and chemical oxygen demands (COD) from industrial wastewaters was investigated. Maximum Ni(II), Cu(II), and COD sorption capacities were 62.3, 75.1, and 1,120.3 mg/g. Simultaneous removal of Ni(II), Cu(II), and COD was investigated in a ternary system.

Industrial wastewaters laden with toxic dyes are required to be treated prior to their disposal in view of their adverse effect on human health and aquatic ecosystem. Thus in this research, CaFe2O4 nanoparticles were prepared and used as adsorbent for elimination of reactive orange 12 dye (RO12) from aqueous medium. The CaFe2O4 nanoparticles exhibit specific surface area of ∼230 m2/g and average pore diameter of ∼2.5 nm. Maximum RO12 removal of 77% was observed at solution pH 2.0 with uptake capacity of 276.92 mg/g. The electrostatic interaction between CaFe2O4 nanoparticles and RO12 was the main driving force behind this adsorption. The kinetic modeling reveal that this adsorption process obeyed the pseudo-second-order kinetic model accurately (R2: 0.988–0.994) indicating the chemisorption behavior. The adsorption experimental data firmly followed the Langmuir isotherm model (R2: 0.997), confirming the monolayer adsorption. Thermodynamic study suggests that the adsorption process is spontaneous (ΔG0 = −8.76 to −3.19 kJ/mol) and exothermic in nature (ΔH0 = –71.86 kJ). A neural network model (optimum topology of 4–7–1) was developed for precise forecasting of RO12 removal (%). The developed model with very high correlation coefficient (0.986) and very low mean squared error (0.00185) was successful for accurate prediction of experimental data.

“…[9][10][11][12][13][14][15] Among them, adsorption technology is an attractive option due to its simple operation, low investment, and potential recovery and reuse of heavy metal ions and oxyanions. [16][17][18] Materials such as zeolites, 19 clays, 20 and layered double hydroxide 21 have been extensively studied for metal ion remediation over these years but these sorbents show low performance for co-removal of heavy metal ions and oxyanions. Therefore, the preparation of sorbents for the co-removal of both heavy metal ions and oxyanions is very useful.…”

Here is synthesized low-cost and green core-shell ZSM-5 zeolite@ layered double hydroxides (ZSM-5@LDH) via a simple in situ coprecipitation method. The structure of the sorbent was investigated using X-ray diffraction, scanning electron microscopy, Fourier transforms infrared, Brunauer-Emmett-Teller, Barret-Joyner-Halenderm, and transmission electron microscope. The ZSM-5@LDH was used for the removal of heavy metal ions include Pb(II), Zn(II), Cd(II), and Cu(II) and oxyanions include As(V), Cr(VI), Se(VI) from aqueous solutions. Synthesized sorbent showed selectivity for removing Pb(II) and As(V) ions. The kinetics models (pseudo-first-order and the pseudo-secondorder models) and adsorption isotherms models (Langmuir and Freundlich models) of sorbent were studied to evaluate the performance of their practical application. The ZSM-5@LDH for removal of Pb(II) and As(V) exhibits a high adsorption capacity (546.25 and 411.41 mg g À1 , respectively) and very high distribution coefficient (K d ) values (4.07Â 10 4 and 8.0 Â 10 6 ml g À1 , respectively), which place it at the top of materials known for the removal of Pb(II) and As(V). As a result, this study indicates that the ZSM-5@LDH may be an ideal material for the selective removal of Pb(II) and As(V).
