“…In addition, they investigated the potential of using α-Fe 2 O 3 NPs as heterogenous catalyst for tetracycline degradation. The result showed that α-Fe 2 O 3 NPs demonstrated excellent performance as a heterogenous catalyst for degradation of tetracycline aqueous solution by the synergistic effect of the UV/Fenton system [97]. The result showed full removal of the three DNAPLs after one day from the (PEI-nZVI) injection.…”

“…They found that MMSNPs adsorption capacity can reach 133 g U(VI) per g MMSNPs; these results indicate that MMSNPs are a promising solution for treating U(VI) contaminated groundwater at extreme pH [95]. In a recent study, Ari et al [97] successfully synthesized α-Fe 2 O 3 NPs via a biosynthesis method using leaf extracts of Azadirachta indica (neem) and a non-toxic precursor salt (FeCl 3 •6H 2 O). In addition, they investigated the potential of using α-Fe 2 O 3 NPs as heterogenous catalyst for tetracycline degradation.…”

Nanotechnology has been widely used in many fields including in soil and groundwater remediation. Nanoremediation has emerged as an effective, rapid, and efficient technology for soil and groundwater contaminated with petroleum pollutants and heavy metals. This review provides an overview of the application of nanomaterials for environmental cleanup, such as soil and groundwater remediation. Four types of nanomaterials, namely nanoscale zero-valent iron (nZVI), carbon nanotubes (CNTs), and metallic and magnetic nanoparticles (MNPs), are presented and discussed. In addition, the potential environmental risks of the nanomaterial application in soil remediation are highlighted. Moreover, this review provides insight into the combination of nanoremediation with other remediation technologies. The study demonstrates that nZVI had been widely studied for high-efficiency environmental remediation due to its high reactivity and excellent contaminant immobilization capability. CNTs have received more attention for remediation of organic and inorganic contaminants because of their unique adsorption characteristics. Environmental remediations using metal and MNPs are also favorable due to their facile magnetic separation and unique metal-ion adsorption. The modified nZVI showed less toxicity towards soil bacteria than bare nZVI; thus, modifying or coating nZVI could reduce its ecotoxicity. The combination of nanoremediation with other remediation technology is shown to be a valuable soil remediation technique as the synergetic effects may increase the sustainability of the applied process towards green technology for soil remediation.

“…Fenton as an advanced oxidation method is characterized by the generation of hydroxyl radicals ( · OH), which is of excellent oxidation activity to degrade organics into CO 2 , H 2 O, and inorganic salts, theoretically. UV, electricity and some other extra energies may be introduced in to assist Fenton reaction 33–35 . Co 3 O 4 with mature preparation process is a traditional UV‐Fenton catalyst, and the advantage of this material is ease preparation and mass production 36 .…”

Chestnut shell‐like hollow spheres of C/Co3O4 nanoparticles was prepared through hydrothermal method, and occupied as adsorbent for the treatment of toxic dyes in wastewater. The obtained material was analyzed by XRD, SEM, TEM, XPS, and BET, the resultant R‐Co3O4/C hybrid hollow spheres were of hollow structure and performed excellent in the adsorption of Congo red (CR). The adsorption capacities of CR and was determined to be 446.43 mg g−1. CR was calculated to be chemisorpted on R‐Co3O4/C hybrid hollow sphere, and R‐Co3O4/C hybrid hollow sphere after been used can be fast regenerated through UV‐Fenton process at pH 3 and showed good cyclic stability.

“…For example, O. Alani et al have reported the treatment of this compound with a heterogeneous photo-Fenton process based on bio-templated Fe 3 O 4 /CuO/C [6]. On the other hand, H. Ari et al [7] have combined a UV-assisted Fenton process with nanostructured biomimetic α-Fe 2 O 3 , thus showing efficient UV-Fenton degradation for TC. This catalyst can also be reused in up to five consecutive cycles without a significant loss in activity.…”

Different composites based on ZnO/Ag3PO4 and ZnO–malachite (Cu2(OH)2CO3) were synthesized in order to determine their effectiveness in the treatment of municipal and industrial wastewaters (mainly polluted by enteropathogenic bacteria, dyes, and heavy metals). The addition of Ag3PO4 and malachite did not significantly modify the physicochemical properties of ZnO; however, the optical properties of this oxide were modified as a result of its coupling with the modifiers. The modification of ZnO led to an improvement in its effectiveness in the treatment of municipal and industrial wastewater. In general, the amount of malachite or silver phosphate and the effluent to be treated were the determining factors in the effectiveness of the wastewater treatment. The highest degree of elimination of bacteria from municipal wastewater and discoloration of textile staining wastewater were achieved by using ZnO/Ag3PO4 (5%), but an increase in the phosphate content had a detrimental effect on the treatment. Likewise, the highest Fe and Cu photoreduction from coal mining wastewater was observed by using ZnO–malachite (2.5%) and ZnO/Ag3PO4 (10%), respectively. Some of the results of this work were presented at the fourth Congreso Colombiano de Procesos Avanzados de Oxidación (4CCPAOx).
