Summary: The coprecipitation of molybdate with ferric iron is commonly used for treating Mobearing acid mine drainage and mineral-processing effluents. This study investigated the effects of pH, neutralization reagents, and co-ions on Mo(VI) removal. It was found that using CaO as base at circum-neutral pH enhanced Mo(VI) removal, with Mo(VI) mainly existing as calcium molybdate in the coprecipitates.

Summary: The electrochemical tests revealed that the addition of ferric iron significantly promoted gold dissolution in acidic thiocyanate system. Thiocyanate facilitated the leaching of gold and associated minerals. Different sulfide minerals exhibited varied galvanic corrosion behaviors towards gold, with some reducing gold dissolution and others inhibiting it. Additionally, the presence of thiocyanate altered the galvanic corrosion behavior of certain minerals, inhibiting gold dissolution in the process.

Summary: The mobility of nano zero-valent iron (nZVI) has a significant impact on its practical application in remediation of contaminated groundwater. This study introduces a novel research system to investigate the two-dimensional transport and retention behavior of colloids and solutes. The results show that the mobility of nZVI is enhanced after phosphate adsorption, posing a potential environmental risk. The migration of phosphate-loaded nZVI (PnZVI) is faster than methyl orange (MO) in the longitudinal direction and exhibits stronger longitudinal dispersion.

Summary: Chemical or biological synthesized iron hydroxides, such as schwertmannite and akaganeite, show high potential for removing chromium ions in polluted wastewater. The adsorption capacity of these materials for Cr(VI) is strong, with maximum adsorption achieved at pH 7.0. Phosphate ions have a greater impact on Cr(VI) adsorption than sulfate and carbonate ions. Moreover, schwertmannite and bioakaganeite exhibit good regeneration ability at temperatures of 288-318 K. Therefore, schwertmannite and bioakaganeite have promising applications in the treatment of acidic/neutral chromate-containing wastewater.

Summary: The breakthrough time of MFI zeolite could be significantly improved by reducing the crystal thickness to a single-unit-cell dimension, resulting in easy access of p-xylene to micropores. Open mesopores did not slow down the mass transfer of p-xylene into zeolite adsorbents, while constricted mesopores did. Mesopore opening is crucial for the desorption behavior of p-xylene, with facilitated diffusion through mesoporous channels allowing for desorption at lower temperatures.

Summary: The study found that the removal of hexavalent chromium by iron oxide is influenced by pH, time, temperature, and adsorbate concentration. The adsorption amount of chromium significantly increases as pH decreases, and the adsorption rate stabilizes after 120 minutes of equilibrium time. Higher temperature enhances the removal of hexavalent chromium, confirming the endothermic nature of the adsorption process.

Summary: The study found that the specific surface area and cation exchange capacity of 1:1 layered clay minerals play a key role in the removal of safranin O, while solution pH and ionic strength have less influence. Experimental results suggested that bilayer SO formation occurs on halloysite nano clay surfaces at high loading levels, while monolayer SO formation occurs on kaolinite surfaces.

Summary: The interactions between cationic dyes and negatively charged mineral surfaces, specifically palygorskite and sepiolite, were investigated in this study. It was found that the dimer molecules formed on the surface of the minerals contributed to the higher TB uptake in addition to cation exchange. Palygorskite was shown to be a better carrier for cationic dyes due to its limited SSA and large CEC values, while sepiolite had a loosely dimeric formation due to its large SSA and limited CEC values.

Summary: This study investigated the sorption characteristics of clay minerals for acridine orange (AO). It was found that clay minerals have higher affinities for AO than inorganic cation Zn2+. Cation exchange was identified as the dominating mechanism for AO sorption. Molecular dynamics simulation results showed that AO formed monolayers and bilayers on the mineral surfaces of non-swelling clay minerals and in the interlayer of swelling clay minerals. Therefore, clay minerals are good candidates for efficient removal of cationic dyes from solution.

Summary: This study tested the removal of anionic dyes MO and ARS from water using negatively charged clinoptilolite and investigated the mechanisms behind it. The results showed that clinoptilolite had a strong affinity for anionic dyes, and the removal might be achieved through electrostatic attraction or hydrogen bonding. Molecular dynamic simulations and FTIR analyses supported the speculation. This study provides a new perspective for the innovative use of negatively charged Earth materials as sorbents for the removal of certain anionic dyes.

Summary: The study found that natural needle-like goethite is a good precursor for obtaining hematite with a large specific surface area and exposed (110) facets. Compared to goethite, the derived hematite showed a sixfold increase in chromium removal capacity under the same experimental conditions. Structural model fitting and molecular dynamic simulations confirmed the superior adsorption performance of hematite for chromium. Based on these findings, efficient and economic permeable reactive barrier (PRB) materials were optimized, with a potential application in PRB medium material field highlighted by a column lifespan of 610 PVs at an initial concentration of 20 mg/L Cr (VI).

Summary: The extensive use of synthetic materials in modern society poses a significant challenge to environmental and water quality. This has led to numerous studies focused on the use of novel materials as sorbents or catalysts for the removal of emerging contaminants from water. Halloysite, a 1:1 layered clay mineral, has shown potential for removing both cationic and anionic contaminants due to its moderate cation exchange capacity and positive charges on the aluminum hydroxyl sheets. The findings of this study suggest that halloysite can serve as a sorbent for the simultaneous removal of organic contaminants with different charges, presenting a new perspective that requires further evaluation and expansion.
