Summary: The research found that selenite in simulated slurry can be reduced by SO2 to form amorphous elemental selenium, while selenate remains unaffected. Increasing SO2 concentration in flue gas accelerates the reduction of selenite, and the reduction reaction is exothermic. Additionally, the oxidation effect of S2O82- competes with the reduction effect of SO2.

Summary: Excessive residual sulfur dioxide in black fungus is harmful to human health and needs to be addressed urgently. This study evaluated the effect of non-thermal treatments on the degradation of residual sulfur dioxide in black fungus and its impact on nutritional composition. The synergistic effect of electrolyzed water and ultrasound showed a relatively ideal degradation rate of sulfur dioxide (83.5%) without loss of total sugar and total phenol in black fungus. Minor damage to the microstructure of black fungus was observed, resulting in darker color. These findings provide a reliable technical guarantee for the removal of sulfur dioxide from black fungus using electrolyzed water and ultrasound.

Summary: Research on Zr- and Al-based metal-organic frameworks (MOFs) for SO2 adsorption showed that frameworks with pore sizes in the range of 4-8 angstroms exhibit optimal sorption capabilities at low pressures. MOFs with NH2 functional groups tend to have enhanced affinity for SO2. Stability tests and density functional theory (DFT) simulations provided insights into the adsorption mechanisms and binding energies of different MOFs towards SO2.

Summary: The study focuses on modelling a cold and swirling airflow in a magnesium burner, and the existence of a significant recirculation zone in the burner is confirmed. The correct simulation of the cold flow and the creation of a recirculation zone are crucial in accurately predicting the high flame temperature and the turbulent mixture of solid fuel and products. Experimental measurements validate the simulation results, with the standard k-epsilon model proving to accurately predict velocity profiles in low swirl cases and the RSM model proving to accurately predict the position, size, and shape of the central recirculation zone in high swirl cases.

Summary: This study presents a simple model for simulating combustion processes in a drop tube furnace, which is much simpler than other available models. The model assumes that a coal char particle remains spherical during combustion and is based on two differential equations describing the evolution of particle temperature and oxygen concentration with respect to time. This model also provides access to local quantities to characterize the combustion process, and its validity is demonstrated through comparisons with experimental data.

This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.
