“…The ZnFe2O4/Ag-TiO2 nanocomposite displays antibacterial activity against both S. aureus and E. coli, also the ZOI for ZnFe2O4/Ag-TiO2 is larger than that of ZnFe2O4 and Ag-TiO2 ( MNPs show strong antibacterial efficiency [30]. This paper exhibits that after composing of nanocomposite, the antibacterial activity is significantly enhanced.…”

In this study, ZnFe2O4 magnetic nanoparticles and ZnFe2O4/Ag-TiO2 nanocomposite were synthesized solvothermally. The prepared materials were characterized using X-ray diffraction, Scanning electron microscopy, Fourier transform infrared spectroscopy and Vibrating sample magnetometer. In addition, the antibacterial performance of materials was evaluated against Gram-positive bacteria (Staphyloccocus aureus) and Gram-negative bacteria (Escherichia coli). ZnFe2O4/Ag-TiO2 nanocomposite was shown more powerful antibacterial efficiency against Staphyloccocus aureus than Escherichia coli. Also, the inhibition diameter of 15±0.2 mm for ZnFe2O4/Ag-TiO2 nanocomposite was measured since the antibacterial activity increased with nanocomposite formation.

“…In traditional sterilization approaches, chlorine gas, chlorine dioxide gas, and ozone gas are the usual effective disinfectants for eliminating the microorganisms. But these approaches have restrictions due to the unwanted property of being toxic gases, which therefore have potential risks to operation workers and other environmental hazards as well [275,276]. Additionally, the results of magnetization and cycling performance revealed that the AgI/CuFe2O4 (18.75% of AgI) composite was separated from the mixture due to its unique magnetic property, stability, and reusability.…”

Adsorption to date is the most effective and utilized technology globally to remove several pollutants in wastewater. In this approach, many adsorbents have been synthesized, tested and used for the elimination and separation of the contaminants such as radionuclides, heavy metals, dyes and pharmaceutical compounds both at lab and industrial scale. However, there are many challenges to adsorption processes such as reducing the high cost, through means of separation of suspending adsorbents to be used again, as well as the ease to synthesize. Two methods that have shown promising results and gained significant interest is that of magnetic nanomaterials and biosorbents due to their effective, safe, eco-friendly, low cost and low-energy intensive material properties. Magnetic nanomaterials act as efficient adsorbents due to their ease of removal of contaminants from wastewater using an applied magnetic field but also their advantageous surface charge and redox activity characteristics. On the other hand, biosorbents have a synergistic effect with their efficient adsorption capacity to remove contaminants, high abundance and participation in waste minimization, helping alleviate ecological and environmental problems. This review highlights, discusses and reports on the state-of-the-art of these two promising routes to adsorption and provides indications as to what are the optimum materials for utilization and insight into their efficiency, reusability and practicality for the removal of pollutants from wastewater streams. Some of the main material focuses are zero-valent iron, iron oxides, spinel ferrites, natural and waste-based biosorbents.

“…In the preparation of NiFe2O4/TA, 0.5 g of NiFe2O4 nanoparticles were dispersed in 20 mL of water under ultrasonic stirring for 1 h. Subsequently, 0.25 g tannic acid was added to NiFe2O4 dispersion and stirred ultrasonically for 2 h. The obtained NiFe2O4/TA was separated with a magnet, and washed. Consequently, the nanocomposites were dried at 70 °C [16].…”

ZnO, NiFe2O4, NiFe2O4/TA and NiFe2O4/TA/ZnO photocatalyts were successfully synthesized and characterized, and they demonstrated significant photocatalytic efficiency under visible-light. The photodegradation rates of congo red (CR) are 35.7%, 19.4%, 25.5% and 91.1% over the ZnO, NiFe2O4, NiFe2O4/TA and NiFe2O4/TA/ZnO for 180 min, respectively. The results display that the NiFe2O4/TA/ZnO has the most excellent photocatalytic efficiency for CR among to the other photocatalysts. Furthermore, NiFe2O4/TA/ZnO may be separated easily from solution by magnet because of the magnetic property of NiFe2O4. The considerable increment in efficiency of NiFe2O4/TA/ZnO can be attributed to synergistic effects between NiFe2O4, the tannic acid (TA) and ZnO, which extend lifetime and hinder the recombination of photogenerated charge carriers. This work presents new perspectives on the use of tannic acid based magnetic photocatalysts in wastewater treatment.
