“…A study confined ionic liquid into ordered mesoporous MCM‐41 to overcome the poor mass transfer or limited adsorption capacity of parent physical sorbent. [ 100 ] In the experiments, x = 0.5 g g −1 at 20 °C/70% RH was determined, the sorption rate was fast under a wide range of humidity conditions, and a low temperature‐driven regeneration cycle may be possible. In addition, the leakage test and corrosion experiment demonstrated the long‐term stability and corrosion‐free nature of the composite sorbent.…”

Freshwater scarcity is a global challenge posing threats to the lives and daily activities of humankind such that two‐thirds of the global population currently experience water shortages. Atmospheric water, irrespective of geographical location, is considered as an alternative water source. Sorption‐based atmospheric water harvesting (SAWH) has recently emerged as an efficient strategy for decentralized water production. SAWH thus opens up a self‐sustaining source of freshwater that can potentially support the global population for various applications. In this review, the state‐of‐the‐art of SAWH, considering its operation principle, thermodynamic analysis, energy assessment, materials, components, different designs, productivity improvement, scale‐up, and application for drinking water, is first extensively explored. Thereafter, the practical integration and potential application of SAWH, beyond drinking water, for wide range of utilities in agriculture, fuel/electricity production, thermal management in building services, electronic devices, and textile are comprehensively discussed. The various strategies to reduce human reliance on natural water resources by integrating SAWH into existing technologies, particularly in underdeveloped countries, in order to satisfy the interconnected needs for food, energy, and water are also examined. This study further highlights the urgent need and future research directions to intensify the design and development of hybrid‐SAWH systems for sustainability and diverse applications.

“…Zinc resources are nonrenewable and are becoming increasingly scarce with continuous exploitation and use. − Consequently, low-grade zinc ores and zinc-containing wastes are receiving increased attention, with researchers exploring ways to extract valuable metals from them. , Iron slag, a solid waste produced during the purification and impurity removal stage of the wet zinc smelting process, is of particular interest. Wet zinc smelting, which accounts for over 85% of the world’s zinc production, has become the dominant method for zinc smelting. − Iron slag, with its high iron and zinc content, has significant potential for comprehensive recovery and utilization. , However, as a viscous material, iron slag retains a high moisture content of over 40% even after treatment with a plate and frame filter press. − This high moisture content can cause slag dampness and stickiness, leading to clumping that severely affects the feeding systems of rotary kilns and smelting furnaces. , This can result in furnace feed disruptions, large fluctuations in furnace conditions, a decrease in zinc oxide quality, and increased labor intensity for workers. , Moreover, the high moisture content of iron slag makes subsequent dehydration processes difficult and energy-intensive. , …”

This study investigates the impact of ultrasonic treatment on the drying kinetics of zinc smelting iron slag. Through the Arrhenius equation, it was found that the reaction order of zinc smelting iron slag remains constant at 1/2 before and after ultrasonic treatment, indicating a proportional relationship between the reaction rate and the square root of the reactant concentration. Despite the increased drying rate of the iron slag due to ultrasonic pretreatment, the reaction order remains at 1/2. Additionally, it was observed that the drying kinetics of untreated iron slag aligns with the Wang and Singh model, while the drying kinetics of ultrasonically pretreated iron slag fits the Page model. The Page model facilitates the prediction of drying rate and drying time for ultrasonically pretreated iron slag, enabling the optimization of the drying process, enhancing efficiency, and comparing drying performance under different conditions. Using ultrasonic pretreatment, the subsequent drying process of iron slag can significantly shorten the time and save energy. These findings provide essential theoretical foundations for optimizing the drying process of zinc smelting iron slag.
