“…In past scenarios, the dye effluent removal was limited to traditionally implemented mechanical stirring for specific contact time, which has a limitation of higher contact time and lesser removal efficiency with relatively higher power investment in comparison to ultrasonication. 45 Deb et al 46 utilized ultrasound wave treatment and reported better removal efficiency of 99.12% for methyl orange within 13 min of optimum contact time. 46 Hence, ultrasound can be a potential approach for dye treatment utilizing lesser power consumption.…”

Porous microwave irradiated activated carbon has been developed and its application for time efficient ultrasonic treatment of Congo‐red (CR) dye. The maximum removal efficiency of 97.73% was obtained using developed adsorbent with ultrasound treatment. The optimum parameters for maximum dye removal were obtained that is, contact time of 2 hr, adsorbent dose of 0.2 g, neutral pH, room temperature, and initial CR‐effluent concentration of 10 mg/l. Adsorption isotherms models, kinetics of the process, and thermodynamic analysis have been evaluated to investigate the adsorption performance. The pseudo second order rate kinetics (R2 = 0.99) and Langmuir equilibrium isotherm (R2 = 0.99) were well fitted to the experimental data. It has been found that microwave synthesized method was better technique in terms of energy savings, and ultrasonic treatment approach was efficient technique in terms of operational time. The combination of microwave‐ultrasonic reported to have an adsorptive capacity of 75.75 mg/g with least energy‐cost consuming approach.

“…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.

“…This is because of the complicated adsorption force derived from covalent bonding, electrostatic interactions, or even physical interactions that lead to good absorption efficiency in the short time and regeneration without the need for large amounts of chemicals. [25][26][27] With these characteristics, the polymer hydrogels are widely used in drug delivery and removal dye, organic, heavy metal pollutants from aqueous solution. [28][29][30][31][32] To date, however, only a few polymer hydrogels for ammonium nitrogen removal have been reported, and most of them are prepared from poly(acrylic acid) (PAA) and their organic/inorganic composites.…”

In this work, we discuss the ammonium nitrogen adsorption and reusability from aqueous solution by using poly(sodium acrylate) (PANa) hydrogels (Polymers 1–6) under different amount of crosslinker and initiator. The PANa hydrogels were synthesized from the neutralized acrylic acid (AA) monomer via free radical thermal polymerization by using ammonium persulfate (APS) as an initiator and N,N′‐methylene‐bisacrylamide (MBA) as a crosslinker. These polymers exhibited glass transition temperatures (Tg) of 68–88°C and Td values (5% weight loss temperature) in the range of 190–221°C under nitrogen atmosphere. The PANa hydrogels had swollen ratios ranging from 387 to 4,063%, related to the crosslinking density. The final equilibrium adsorption capacity of the polymers was in the range of 20–39 ppm with an initial ammonium nitrogen concentration of 100 ppm. Among them, Polymer 3 without MBA crosslinker displayed the highest swollen characteristic along with the most efficient adsorption capacity. In comparison, the as‐prepared high crosslinking density hydrogels showed relative lower adsorption capability but higher reusability. The polymer composition in this work determines the ability to absorb and desorb ammonium nitrogen compound.
