“…The addition of clay minerals can affect the microenvironment in the soil and can change the occurrence state of heavy metals [34]. Clay minerals can self-dissolve to produce anions, which will combine with heavy metal cations in the soil for surface adsorption and coordination with ions [35,36], thereby greatly reducing the effectiveness of heavy metals in the soil, changing the bioavailability and mobility of heavy metals, and alleviating heavy metal stress [37]. The results indicated that the application of illite can reduce the content of HCL-extractable heavy metals.…”

Phytoremediation is considered an effective strategy for remediation of heavy-metal-contaminated soil in mining areas. However, single-species plants cannot reach the highest potential for uptake of heavy metals due to inhibition of their growth by high concentrations of heavy metals in the soil. Therefore, this study has explored the effects of illite application and two plant species’ co-cropping on soil quality, plant growth, and heavy metal transformation in a soil–plant system. The results reveal that the addition of 1% (mass fraction) of illite significantly enhances soil pH. The co-cropping of Ilex cornuta and Epipremnum aureum is beneficial for improving the organic matter content of the soil. The contents of EDTA-extractable Pb, Zn, and Cu were significantly reduced by 29.8–32.5%, 1.85–5.72%, and 30.0–32.9%, respectively, compared to the control. The co-cropping of Ilex cornuta and Epipremnum aureum promoted enrichment effects of Epipremnum aureum on Pb and Ilex cornuta on Cd (p < 0.05). The co-cropping pattern lowered the biomass of Ilex cornuta and Epipremnum aureum; however, co-cropping of Ilex cornuta and Epipremnum aureum promoted the elimination of Pb, Zn, Cu, and Cd from the soil at 13.0–75.8%, 11.1–38.2%, 8.39–88.4%, and 27.8–72.5%, respectively. It is concluded that illite application combined with co-cropping of Ilex cornuta and Epipremnum aureum is highly effective for the elimination of Pb, Zn, Cu, and Cd from contaminated soil. This study provides a theoretical basis and pathway for the restoration of heavy-metal-contaminated soil in mining with the application of bentonite combined with phytoremediation.

“…Thus, the addition of ZrO 2 to the DD3 clay plays an opposite role in the absorbance compared to the photocatalytic degradation. The absorbance decrease with the addition of ZrO 2 in the clay can be explained by the formation of ZrSiO 4 component characterized by a great optical reflection of the grains [32].…”

“…As a result, the conduction band of MgO is higher than the conduction band for ZrO 2 , and, therefore, there may be a rapid transfer of electrons formed in the conduction band (C B) at MgO to the CB for ZrO 2 (this prevents recombination) [39][40][41]. The CB edge potentials of MgO (− 3.20 eV) and ZrO 2 (− 0.88 eV) are negative compared to the standard redox potential EΘ O 2 ∕ • O (− 0.33 eV vs. NHE) [32,41]. Therefore, the electrons for MgO and ZrO 2 can reduce O 2 to • O (Eqs.…”

To purify water at low cost for our daily life, the effect of ceramic-based (mullite–cristobalite) and (mullite–zircon) powders doped with different amounts of magnesium oxide (MgO) (10 and 20 wt%) was studied. These compounds are made of a local raw material DD3 with addition of zirconia (ZrO2) to create an open porosity. The powders were prepared by the traditional mixing method with the help of an automated crushing. The effect of MgO doping on structural, morphological and photocatalytic properties of the material was studied by various analytical techniques such as X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, infrared, and UV–visible spectrometry. The results of XRD proved that there was a deformation in the crystal structure of the two types of ceramics after addition, which resulted in a shift of the spectra to the right, while SEM proved the presence of pores with a larger size as the proportion of MgO increases. The chemical composition of the basic components of the ceramic compounds as well as the additive was confirmed with EDS and IR spectra. The final results show that ceramics with added zirconia (DD3Z) and doped with 10% of MgO have a better photocatalytic efficiency than ceramics without zirconia. This important effect could be related to the higher rate of porosity, which provides a more active surface. The 10% MgO content showed a high photoactivity of 77.33% in only 15 min. The maximum hydrolysis rate obtained with Orange II was 92.95% after a period of 45 min with DD3Z/MgO powders.

The utilization of natural clay minerals for the adsorption of endocrine‐disrupting chemicals (EDCs) presents a cost‐effective and environmentally friendly approach. However, the hydrophilic nature of clay minerals' surface limits their efficacy in removing these hydrophobic pollutants. To overcome these limitations, this study employed two cationic surfactants, cetylpyridinium chloride (CPC) and cetyltrimethylammonium chloride (CTAC), to modify kaolin minerals to enhance their capacity to adsorb a specific type of EDCs, bisphenol A (BPA), and its analogs. The experimental results validated that the surfactant‐modified kaolin exhibited remarkable efficiency in removing BPA from water. The equilibrium adsorption capacities of CPC‐K and CTAC‐K for BPA were determined to be 11.4 mg/g (pH = 2.0–8.0) and 13.4 mg/g (pH = 2.0–6.5), respectively. Kinetic analysis revealed that the BPA adsorption followed a pseudo‐second‐order kinetic process, while isotherm analysis suggested that the BPA adsorption was better described by the Freundlich model (R2 = 0.993–0.998). The surfactant‐modified kaolin demonstrated a retention of over 70% of its initial adsorption capacity after five cycles of desorption and regeneration, further confirming its potential for recycling. Additionally, these modified adsorbents exhibited excellent compatibility in removing bisphenol analogs. These findings provide valuable insights into the practical application of surfactant‐modified clay minerals for the elimination of hydrophobic organic pollutants from water.
