“…171 Additionally, there is ongoing investigation into utilizing other waste materials from various industries for the synthesis and modication of zeolites, with the aim of increasing their adsorption capacity. 170,[172][173][174] Natural zeolites are highly promising materials for removing heavy metals from various sources that contaminate water. The unique properties of natural zeolites, such as ease of ion exchange, adsorption, dehydration, and rehydration, as well as their eco-friendliness, low cost, regenerability, accessibility, and availability, make them an excellent choice as adsorbents for removing heavy metal ions from wastewater.…”

“…Natural soil resource is almost zero-cost with huge stock, in which the abundant Si and Al components could be used to constitute zeolite frameworks. Meanwhile, the Fe composition from soil could modify zeolite performance, improving adsorption and redox chemistry capacity to detoxify the muti-valent heavy metal ions. , Considering the wide distribution of natural soil resources, using soils as raw materials for zeolite synthesis is the best choice with no geographical limitation. Besides, if the soils near polluted areas or even contaminated soil could be in-situ-transformed into zeolite materials directly for soil remediation, it would significantly improve the remediation flexibility and reduce transportation fees and after-costs.…”

Herein, we developed a universal "soil for soil remediation" strategy to utilize soil resources for cation-/aniontype heavy-metal-contaminated soil remediation. The representative natural soils fetched from 12 different areas in China have been universally converted into Fe 2 O 3 -CAN (hydroxycancrinite) zeolite composite materials. Furthermore, we discover that due to the presence of exchangeable Na + and OH − in CAN channels together with the intrinsic surface adsorption function of Fe 2 O 3 -CAN, Fe 2 O 3 -CAN holds distinctive cation/anion dual ion-exchange functions and strong adsorption capacity, which could synergistically remediate cation-/anion-type HM-contaminated soil. When 25 g/kg Fe 2 O 3 -CAN is added into Cd/As polluted soil (100−200 ppm), Cd 2+ and AsO 2 − in soil could be immobilized simultaneously and the Cd/As bioaccumulation in the harvested vegetables is dramatically suppressed with reduction ratios of 48.1−67.0%, effectively reducing the HM enrichment in the phytosphere. Overall, this work confirms the high universality of Fe 2 O 3 -CAN synthesis using different types of natural soils and demonstrates that the as-synthesized Fe 2 O 3 -CAN composite material can be further effectively used for soil remediation. The "soil for soil remediation" strategy developed here could improve the flexibility and economy of soil remediation, which can be extended to a broad range of locations worldwide.

“…At present, the remediation methods of oil‐polluted soil include physical, chemical, biological and combined remediation 8 . Limited by the high energy consumption of physical remediation and the slow process of bioremediation, chemical remediation is favored by researchers and has been widely used for in‐situ remediation of groundwater and soil.…”

In recent years, the oil pollution problem on the Loess Plateau in western China is becoming increasingly serious, therefore, the use of hydroxyl radical (·OH) advanced oxidation process has increased due to its ability to efficiently degrade total petroleum hydrocarbon (TPH) in soil. However, the ability to produce ·OH of different oxidants varies widely, and the removal effect of specific pollutants has fluctuations and differences. The objective of this study is to screen the best oxidant according to the physico‐chemical properties and pollution situation of polluted soil, and to reveal the degradation mechanism of pollutants. In this study, we employed sodium ferrate (Na2FeO4) to produce ·OH for the degradation of TPHs in aged oil‐polluted soil located in the western part of the Loess Plateau in China. The results showed that the removal rates of TPH in the soil samples by hydrogen peroxide (H2O2), sodium persulfate (Na2SO4) and Na2FeO4 could reach 45.5%, 62.4%, and 65.6% respectively. The ·OH produced during the process played a major role in TPH oxidation with a contribution of more than 80%; H2O2 was intermediate substance that generated ·OH, biochar could induce the production of ·OH, the addition of biochar could activate H2O2 to promote the generation of ·OH and the removal rate is significantly increased by 19.2%. In situ remediation of polluted soil on the Loess Plateau using Na2FeO4, with a TPH degradation rate of 87.5%. The results of this study will provide a new method for the efficient degradation of TPH in loessial soil.
