“…Compared with ultrapure water, the removal experiments of CIP in actual water (tap water and lake water) were carried out to investigate the performance of MBC. The characteristics of actual water were shown in Table S1 [51]. Totals of 75.8% and 72.4% of CIP were removed in tap water and lake water (Figure S2g).…”

An economical corncob biochar-based magnetic iron–copper bimetallic nanomaterial (marked as MBC) was successfully synthesized and optimized through a co-precipitation and pyrolysis method. It was successfully used to activate H2O2 to remove ciprofloxacin (CIP) from aqueous solutions. This material had high catalytic activity and structural stability. Additionally, it had good magnetic properties, which can be easily separated from solutions. In MBC/H2O2, the removal efficiency of CIP was 93.6% within 360 min at optimal reaction conditions. The conversion of total organic carbon (TOC) reached 51.0% under the same situation. The desorption experiments concluded that adsorption and catalytic oxidation accounted for 34% and 66% on the removal efficiency of CIP, respectively. The influences of several reaction parameters were systematically evaluated on the catalytic activity of MBC. OH was proved to play a significant role in the removal of CIP through electron paramagnetic resonance (EPR) analysis and a free radical quenching experiment. Additionally, such outstanding removal efficiency can be attributed to the excellent electronic conductivity of MBC, as well as the redox cycle reaction between iron and copper ions, which achieved the continuous generation of hydroxyl radicals. Integrating HPLC-MS, ion chromatography and density functional theory (DFT) calculation results, and possible degradation of the pathways of the removal of CIP were also thoroughly discussed. These results provided a theoretical basis and technical support for the removal of CIP in water.

“…The DFT calculation was used to justify the results obtained from micro-electrolysis of 3D-GN@Cu 0 and also explained the observed synergistic effect between graphene and nZVCs for the removal of metronidazole. Zhang et al (2020b) performed sulfamethazine (SMZ) 38 degradations using a synergistic approach involving nZVC and sonolysis promoted activation of persulfate to give SO4 •-. The optimal conditions for the complete SMZ removal includes a PS dose of 0.5 mM, nZVC conc.…”

“…The nano-zero-valent of some metals could be used in removing pollutants from soil and water such as thallium (Tl) removal by nano-zero-valent Mn (Li et al 2020), lead (Pb) by nano-zero-valent Sn (Mahmoud and Abdelwahab 2021), antibiotics by nano-zero-valent tungsten (Ye et al 2020), antibiotic sulfamethazine by nanosized zerovalent copper (Zhang et al 2020) and uranium (U-VI) by nano zero-valent iron (Zhang et al 2021). The nano-zero-valent iron (nZVI) or iron nanoparticles is a promising remediator material could be used in environmental remediation.…”

T HE human activities include the agricultural, industrial and other activities. The agricultural sector is considered the main source for our life's supplies. However, the agricultural activities or practices might result many pollutants such as applied mineral fertilizers, pesticides, effluents from domestic and industrial sewages and vehicular emissions. Therefore, a remediation to remove or decrease the pollutants in soil and water is needed for the environment protection. This remediation has several classic strategies several years ago, but a promising and new approaches have been established particularly nano-remediation. This nano-remediation depends on the applied nanomaterials in removing pollutants from soils and water through nano-bioremediation and nano-phytoremediation. The most important nanomaterials that have potential in removing pollutants from contaminated soils and water are nano-silica, nano-zero-valent of iron, nano-sized iron sulfide particles, nano-ZnO and others. However, many challenges or open questions are still needing a justification because using nanomaterials in higher concentrations are toxic to plants and agro-environment. Are these nanomaterials stable under environmental conditions or will be converted into toxic ones or still need to be identified for sustainable nano-remediation? Is there any possibility to enter the nanomaterials or other toxic compounds the food chain through these plants? Therefore, a lot of further research is needed concerning the nano-remediation in removal the agro-pollutants.
