Summary: Improper disposal of metal-containing wastes harms the environment and human health. This study investigates the sorption and desorption of Cr6+, Cu2+, and Mn2+ by modifying polyacrylamide/methylcellulose hydrogels with bentonite or hydrotalcite. The nanocomposite produced by calcining hydrotalcite at 550 degrees C exhibits the best retention properties.

Summary: This study investigated the effectiveness and mechanism of using hydrous zirconium oxide (HZrO2) combined with calcite, bentonite, and zeolite for controlling internal phosphorus liberation from sediment. The results showed that calcite, calcium-modified bentonite (CaBT), and calcium-modified zeolite (CaZ) all enhanced the adsorption of phosphate (PO43-) onto HZrO2. The combined amendment materials effectively prevented sedimentary P release by immobilizing mobile P in the sediment and uptake of dissolved reactive P (DRP) from interstitial water. The capping materials also intercepted sediment P release by forming a P static layer and had low re-releasing risk under specific conditions.

Summary: This study investigates the sorption behavior of bisulfide (HS-) onto bentonite, and finds that HS- sorption occurs faster and has a higher equilibrium sorption capacity at higher temperatures. The study also suggests that the irreversible sorption of HS- onto bentonite may be due to the chemical reactions between HS- and the iron present in bentonite, forming iron monosulfide (FeS). These findings provide critical information to better understand the sorption mechanism of HS- on bentonite and reduce HS- transport in deep geological repositories.

Summary: In this study, the growth behavior of redox sensitive Fe0 nanoparticles (nZVI) was found to vary on different clay surfaces. The non-swelling kaolinite (K-nZVI) showed dominant surface growth characteristics, forming larger nZVI particles (>24.8 +/- 7.4 nm) with positive zeta potential. On the other hand, the swelling bentonite (B-nZVI) exhibited negative zeta potential, mainly due to the surface charge of bentonite clay. This surface-dependent variation resulted in higher and faster removal of oxy-anions with K-nZVI, while B-nZVI showed higher sorption of cations. XPS and pXRD analysis confirmed the major removal mechanisms of reductive sorption, co-precipitation/complexation, electrostatic attraction, and complexation. The findings highlight the potential applications of K-nZVI and B-nZVI in removing specific contaminants from different types of water sources.

Summary: Biogenic manganese oxides, found in the uranium mill tailings at the Ningyotoge U mine in Japan, are crucial in sequestering radioactive radium. This study investigated the nanoscale processes of Mn oxide formation by the basidiomycete fungus Coprinopsis urticicola in the lab using electron microscopy and X-ray analysis. The results showed that Cu2+ and DPI inhibit both fungal growth and Mn oxidation, while Zn2+ has no significant effect. Mn2+ infiltrated the fungal hyphae and formed nanoscale aggregates, which eventually precipitated as fibrous nanocrystals. These findings shed light on the mechanisms of Mn oxidation by filamentous fungi in uranium mill tailings.

The experiments revealed that the sorption isotherm of TPU has almost no temperature dependency. The diffusion coefficients obtained from the experiments show dependency on temperature and relative humidity range.

Summary: Medical waste includes infectious, hazardous, radioactive, and potentially toxic elements (PTEs) that are produced in the treatment, diagnosis, and immunisation processes of animals and humans. Common technologies for its safe management are incineration and sterilisation. Proper disposal and land application of medical waste ash are crucial to prevent the release of PTEs and ensure environmental safety. This review paper critically examines the dynamics of PTEs, environmental and health implications, and misconceptions regarding medical waste.

Summary: Sorption thermal energy storage (STES) using zeolite 4A/water vapor as the working pairs has great potential for inter-seasonal thermal energy storage in building heating. In this study, a STES experimental bench was constructed, and charging/discharging experiments were conducted to analyze the thermal energy chain during the process. The results showed that a significant amount of thermal energy was lost through the reactor outlet during the charging process, hindering the improvement of thermal energy storage performance of the STES system. Additionally, it was found that higher charging temperature and lower charging air humidity could enhance the thermal energy storage performance.

Summary: Long-term use of phosphorus fertilizers can lead to phosphorus leaching from agricultural soils, causing water pollution and eutrophication. This laboratory study investigated the effect of different concentrations of monopotassium phosphate (MKP) on phosphorus and cation leaching from two agricultural soils. The results showed that increasing MKP concentration decreased pH and calcium concentration in leachates, but increased electrical conductivity, sodium, and potassium concentrations. Appropriate MKP concentrations can help reduce phosphorus loss.

Summary: Soils in areas with intensive agriculture have high potassium levels, which may lead to potassium being transferred to groundwater through leaching. This study evaluated the extractability and leaching of potassium from soils using various extractants, and calculated change points to predict the rate of potassium leaching. The findings recommend using specific extractants like CaCl2, HNO3, and H2O to assess the risk of potassium losses, and suggest using calculated degree of potassium saturation as an environmental indicator for evaluating the possibility of potassium leaching.

Summary: The long-term application of organic and inorganic fertilizers can lead to contamination of greenhouse soils with heavy metals. This study found that greenhouse soils had lower adsorption capacity for heavy metals compared to agricultural soils, making them more susceptible to leaching. The desorption experiments showed that the percentage of heavy metal desorption increased with higher concentrations of added heavy metals. The findings suggest that continuous vegetable production and fertilizer application in these greenhouse soils can result in changes in soil properties and heavy metal mobility, posing risks to human health and groundwater quality.
