Sorption is the collective term used for both adsorption and absorption. Absorption involves the diffusion of molecules of a substance into a material due to the material’s ability to dissolve the substance, while adsorption involves the attachment of molecules of a substance to a material surface. Sorption has been gaining significant attention in recent years as a promising separation technique because it is simple, efficient, and low-cost. Some new perspectives and applications of sorption are Sorption in Nanotechnology, water treatment, gas separation and Medicine and Biotechnology. Sorption is a promising alternative to traditional separation methods, which have significant economic and environmental drawbacks. Sorption can serve numerous applications across various sectors, including industry, medicine, and energy. This technique is easy to execute, energy-efficient, and economical, and has the potential to develop sustainable solutions through resource recycling, green technology and waste reduction. In this chapter, we discussed the impact of green technology on sorption processes, recent developments and the challenges that needs more research that can proffer solution and make sorption processes more reliable and attractive.
