Radionuclides Removal from Aqueous Solutions: A Mini Review on Using Different Sorbents
In this study, mini review is presented on the use of different sorbents for radionuclides removal of from water. Four sorbents categories were considered: carbon-based, nanomaterials, bio-sorbents, and miscellaneous sorbents. Carbon-based sorbents showed excellent removal performance towards radionuclides, owing to the high specific surface area and abundant oxygen-containing functional groups. While Fe0 and Fe0-based composites was found to exhibit rapid sorption rate, high removal capacity, and strong redox performance for radionuclides, indicating that such nanomaterials can be very promising for in-situ removal of radionuclides, once their drawbacks (aggregation and poor mobility) are overcome. The use of bio-sorbents showed high potential of such materials to remediate radioactive contaminated water under specific environmental conditions. The critical review in this study shall represent a great contribution to the potential researchers and decision makers choosing the highly efficient, feasible, and environmentally friendly sorbents for the removal of radionuclides from aqueous solutions.

Comparative Study of Bare and Emulsified Nanoscale Zero-valent Iron for Nitrate and Phosphorus Removal
This work aims to demonstrate the effect of polyethylene sorbitan monolaurate (PSM) on the properties and reactivity of nanoscale zero-valent iron (nZVI). PSM was used in this work to prepare an emulsified nZVI to overcome the particle aggregation phenomenon of nZVI and show the prepared particles with good properties. For that purpose, TEM, XRD and reactivity test of nitrate and phosphorus were performed to show the changes in the performance of nZVI after being emulsified with PSM. The results showed that the emulsified (PSM) greatly improved the removal efficiency of nitrate. Moreover, PSM enhanced the particle dispersion of nZVI and showed the particles with good properties.The results showed that the emulsified nZVI with PSM was also suitable for reduction of nitrate even at a wide range of pH. This study proposed that the emulsified nZVI could have a significant contribution in the aspects of water treatment only for the reducible contaminates.

Effect of Nano Zero Valent Iron Delivery Method into Porous Media on Phosphorus Removal from Groundwater
The main aim of this study is to investigate the effect of the delivery method of nano zero valent iron (NZVI) into porous media on the removal of phosphorus from groundwater. Different column experiments were conducted considering injection and permeable reactive barrier (PRB) approaches using sand-packed column with 65 cm length and 10 cm inner diameter. Results revealed that Injecting 10 g of NZVI into C4 resulted in the highest sorption capacity and average removal efficiency of 25 mg/L phosphorus concentration over 14 days with 197.76 mg-P/g-NZVI and 84.8% respectively. The dissolved oxygen levels in the effluent samples of the NZVI column were declined due to the oxidation process of NZVI, which was accompanied by a lower ORP values. The change of the delivery methodology of NZVI into porous media affected its capacity to remove phosphorus, revealing that injection could be better than PRB in terms of the reactive performance.

Upgrading of Aerobic Sequencing Batch Reactor System with Adding Nanoscale Zero Valent Iron for Wastewater Treatment
The aim of this study was to investigate the effect of nano-scale zero-valent iron (nZVI) on the performance of aerobic sequencing batch reactors (SBRs) in terms of COD, phosphate removal and microbial species growth. Two lab scale SBRs were operated simultaneously for sixty days with and without adding nZVI. The reactors were fed with synthetic wastewater and acclimated with seed sludge which was taken from a full-scale municipal wastewater treatment plant in Istanbul. As a result, next generation sequencing technology analysis confirmed that the addition of nZVI in R2 promoted some bacterial types such as Xanthomonadales and inhibited others such as Clostridiales, confirming that the effect of nZVI on the bacterial growth was genera dependent. In addition, the phosphate and COD were completely removed at the end of the study and slightly enhanced with 15 % after the addition of nZVI in R2.

Enhancement of Nanoscale Zero-Valent Iron Stability in Aqueous Solution Via Metal Hydroxide Coating
Concerns have been increased regarding the behavior of nanoscale zero-valent iron (nZVI) in subsurface environmental remediation applications. In this study, the iron particles were coated by magnesium hydroxide (Mg(OH)_2) shell in order to improve their suspension stability in aqueous solutions. Sedimentation tests were conducted for different ratios of the coating material to evaluate the enhancement of particles stability and to determine the optimum coating ratio. Results of sedimentation tests showed that, the coated iron particles Mg(OH)_2-CnZVI exhibited better stability performance than that of bare nZVI (BnZVI). Additionally, optical absorbance results depicted that Mg/Fe coating ratios of 0.8 and 1 showed less aggregation potential than that of the other coating ratios and BnZVI as well. Moreover, beside the enhanced stability, the addition of the nonmagnetic coating layer protected the nZVI core from the rapid corrosion. Further studies should be conducted to investigate the sustainability of the coated nZVI reactivity.
