“…Psidium guajava leaves extract was utilized to synthesize green nickel oxide nanoparticles (PG-NiONPs) [10]. Yahya et al [53] investigated the characterization, preparation and application of organoclay nano-adsorbent for the removal of pollutants from wastewater. They concluded that the Organoclay could be considered a cheap and efficient adsorbent for the removal of most of the chemical pollutants from wastewater that could be of socioeconomic and environmental relevance.…”

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.

“…The most common surfactants used to prepare organoclay are cationic (especially quaternary ammonium salts), zwitterionic and nonionic. When using cationic and zwitterionic surfactants, clays are modified through the exchange of exchangeable cations present in the interlayer space, whereas in the case of nonionics, modification can occur via dipole-ion interactions, thus leading to hybrid materials with dual behavior, hydrophilic-hydrophobic [29][30][31][32][33].…”

Polymer clay nanocomposites, which can exhibit many superior properties compared to virgin polymers, have gained increasing interest and importance in recent years. This study aimed to prepare composites of two organoclays with unusual ratios and different degrees of lyophilicity with low-density polyethylene and compare their textural structures and thermal and mechanical properties with those of virgin polymer. For this purpose, firstly, organoclays, hydrophobic and superhydrophobic organoclays (OC and SOC), were prepared by solution intercalation method using cetyltrimethylammonium bromide with and without addition of a hydrocarbon substance. Then, using both organoclays, polyethylene organoclay composites were prepared and characterized using X-ray powder diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and Fourier transform infrared spectroscopy (FTIR) techniques. Additionally, tensile and hardness tests were performed to determine the mechanical properties of the composites, and differential scanning calorimetry (DSC) thermograms were taken to examine their thermal behavior. XRD patterns and HRTEM images of hydrophobic and superhydrophobic organoclays and the composites show that the characteristic smectite peak of the clay shifts to the left and expands, that is, the interlayer space widens and, in the composites, it deforms immediately at low clay ratios. HRTEM images of the composites prepared especially with low clay ratios indicate that a heterogeneous dispersion of clay platelets occurs, indicating that nanocomposite formation has been achieved. On the contrary, in the composites prepared with high clay ratios, this dispersion behavior partially turns into aggregation. In the composites prepared using up to 20% by weight of superhydrophobic organoclay, extremely stable and continuous improvements in all mechanical properties were observed compared to those of the composites prepared using hydrophobic organoclay. This indicates that by using superhydrophobic organoclay, a ductile nanocomposite of polyethylene containing inorganic components in much higher than usual proportions can be prepared.
