“…Therefore, the optimal pH conditions for contaminants removal by using ZVI in the absence of H 2 O 2 depend on the intrinsic characteristics of the contaminant and on the mechanism of its removal [23]. Comprehensive details of mechanism, kinetic parameters, benefits and application of ZVI in the presence and absence of H 2 O 2 for water and wastewater treatment are already available (see [10,18,20,45,58,59,60,61,62,63,64,65,66], and references therein).…”

Effect of pH on Zero Valent Iron Performance in Heterogeneous Fenton and Fenton-Like Processes: A Review

Heterogeneous Fenton processes with solid catalysts have gained much attention for water and wastewater treatment in recent years. In the field of solid catalysts, zero valent iron (ZVI) is among the most applicable due to its stability, activity, pollutant degradation properties and environmental friendliness. The main limitation in the use of ZVI in heterogeneous Fenton systems is due to its deactivation in neutral and alkaline conditions, and Fenton-like processes have been developed to overcome this difficulty. In this review, the effect of solution pH on the ZVI-Fenton performance is discussed. In addition, the pH trend of ZVI efficiency towards contaminants removal is also considered in oxic solutions (i.e., in the presence of dissolved O2 but without H2O2), as well as in magnetic-field assisted Fenton, sono-Fenton, photo-Fenton and microwave-Fenton processes at different pH values. The comparison of the effect of pH on ZVI performance, taking into account both heterogeneous Fenton and different Fenton-like processes, can guide future studies for developing ZVI applications in water and wastewater treatment.

“…CrFP exhibited clear fiber shape and its surface was smooth, but after amination reaction, the surface of the ACrFP sorbent was tough and superficial irregular. The corresponding EDS spectrum of ACrFP was displayed in Figure 2c, it was confirmed that nitrogen element content was 16.70% (atom%) and increased 6.40% in comparison to CrFP (10.3%) [10], suggesting that amino groups of TEPA have grafted on CrFP [13].…”

“…Differently conventional technologies have been carried out to treat reactive dyes from effluents including flocculation, sedimentation, coagulation, precipitation, advanced oxidation, membrane filtration, electrochemical decolourization, etc . Recently, some new technologies such as plasma irradiation , zero‐valent iron coupling technology , photocatalytic membrane reactor , and electrochemical advanced oxidation process (EAOP) are also utilized for removal of dyes. Adsorption is one of the most effective methods for removal of dyes, oily wastes, heavy metals, and organic pollutants from water .…”

Amine resin (ACrFP) based on chromium (III)‐fibrous protein (CrFP) was synthesized by solvothermal reaction using tetraethylenepentamine, and its utilization in removing two kinds of anionic dyes (reactive brilliant red X‐3B and K‐2BP) was investigated. This adsorbent with protonated amine groups was characterized by SEM‐EDS, zeta potential, FTIR, Raman, and XPS. EDS analysis illustrated that the nitrogen content of ACrFP increased 6.40% compared with CrFP, suggesting grafting of amine groups into the framework of CrFP. Raman analysis of anionic dyes in solution and the ACrFP resin which has adsorbed dyes suggested that X‐3B and K‐2BP in solution have been loaded on solid, and XPS measurement of ACrFP, X‐3B‐ACrFP, and K‐2BP‐ACrFPfurther affirmed the results of Raman. Both sorption isotherms of X‐3B and K‐2BP were favored in lower temperature. About 0.1 mol/L of HCl could desorb reactive red dyes from ACrFP and the regenerated adsorbent could reuse several cycles. © 2018 American Institute of Chemical Engineers Environ Prog, 38: S196–S204, 2019

“…Zero-valent iron is another form of iron used in water treatment. Although zero-valent iron use as a phosphate adsorbent has been investigated Almeelbi and Bezbaruah 2012;Wu et al 2013a;Wen et al 2014), and it has been used to remove other water pollutants (Fu et al 2014;Bigg and Judd 2000;Xu et al 2017;Lu et al 2016;Drenkova-Tuhtan et al 2013;Hamdy et al 2018), its research and application is not as common as divalent and trivalent iron. For this study, the plates were rusted (iron oxide) by the presence of water, air moisture, and natural organic matter placed between the plates to enhance the effectiveness of phosphorus adsorption by forming iron oxides on the plate surface (Weng et al 2011).…”

The presence of phosphorus (P) in excessive quantities can lead to undesired conditions, such as cyanobacterial/algal bloom. The overenriched hypertrophic conditions or the excess amounts of nutrients (nitrogen and P, P being the primary nutrient of concern) are the major cause of harmful cyanobacterial blooms, which can be toxic and can also lead to oxygen depletion and anoxic respiration (hypoxia) in the hypolimnion. The presence of iron compounds has been shown to bind phosphorus and diminish harmful algal blooms. Therefore, an iron-platespacked reactor has been designed to reduce P in surface water. This costeffective and easy-to-install system has shown promising results in phosphorus reduction.
