Water being the essential commodity of life is constantly polluted by anthropogenic activities which is a serious threat to human health and environment. A number of water treatment technologies (adsorption, oxidation, coagulation, membrane technologies, etc.) are in use for the reclamation of portable water. Adsorption being the most versatile technique is largely used for the reclamation of industrial wastewater but is not much effective in case of seawater being loaded with inorganic ions. For saline water treatment, cost effective method is the use membrane technology. Reverse osmosis membranes are preferably used for water desalination purposes that have numerous benefits over other water treatment technologies. Hexagona1 boron nitride (h-BN), a two-dimensiona1 (2D) substance that has revolutionized the field of 2D substances, has demonstrated remarkable capabilities as an adsorbent and as ideal material in the construction filtration membrane in the reclamation of wastewaters. Exfoliation and chemical vapor deposition methods are extensively used for h-BN synthesis. Along with these two methods, based on molecular dynamics insights, density functiona1 theory (DFT) in the field of (h-BN) nanosheets and several modern investigations into h-BN membrane filtration and pollutant adsorption have been discussed in this chapter. All the described findings point toward the promising potential of h-BNs in water filtration processes. We have also presented a summary of experimental work that looked into the efficiency of h-BN for solute separation. The h-BN not only has a lot of potential for adsorption for a variety of dyes, oils, and metal ions, but it also has a lot of recoverability. Despite various studies on this topic, there are still study gaps, as attempted to be described in the chapter.
