“…This can occur when the adsorption process is exothermic, meaning that heat is released during the adsorption process. The release of heat can cause a decrease in the driving force for adsorption, resulting in a decrease in the adsorption rate [23,74]. Some studies were found in which it is reported that the adsorption of F − increases with increasing temperature, which is an indication that the adsorption process is endothermic.…”

Water pollution, particularly from elevated fluoride ion (F−) concentrations, is a significant challenge in many developing countries, particularly those relying on groundwater. The stable form of fluoride, F−, poses health risks, leading to concerns about various diseases and harmful effects. Despite global efforts, high F− concentrations (>1.5 mg L−1) persist in numerous countries, requiring effective and sustainable removal methods. Adsorption, known for its simplicity, cost-effectiveness, and efficiency, stands out as a promising technique for F− removal from drinking water. Successful commercial implementation necessitates the optimization of separation conditions. This systematic literature review focuses on the adsorption process for F− removal, exploring parameters such as temperature, adsorbent particle size, pH, adsorbent mass, and co-existing ions for efficient removal. Observations indicate that, despite the utilization of a diverse range of adsorbents, several limitations persist. These include low adsorption capacity, a sluggish adsorption rate, a restricted pH range, and high associated costs. The mechanistic understanding of adsorption and the ongoing development of novel adsorbents remain focal points for future research. Additionally, there is a need to explore alternative kinetic models grounded in statistical factors and give due consideration to thermodynamic studies.

“…There are numerous application areas which make MOFs especially attractive for further in-depth studies. Those include (but are not limited to) separation of diverse organic substrates [5], including industrially important ones (in particular, cyclohexane/benzene) [6][7][8][9], catalysis (including photocatalysis) [10][11][12][13][14][15], sensor systems [16][17][18][19][20][21][22][23][24][25], removal or important inorganic pollutants [26][27][28][29][30][31], etc. Most of these features are due to the ability of MOF to act as sorbents: those having 3D structure can absorb various substrates into the pores.…”
