“…The BET surface areas of ES and ZnES were predicted as 0.188 and 7.33 m 2 g -1 , respectively; the increase in the surface area of the modified eggshell (ZnES) could be the result of the modification of the eggshell with ZnCl 2 . It has been reported by several researchers that modification with metal ions tends to change the surface characteristics; it either increases or decreases the surface area, pore volume, and pore diameter [43]. The pore volumes are 0.00298 and 0.0315 cm 3 g -1 with pore sizes of 755.8 and 459.5 Å, respectively.…”

“…3 Results and Discussion The pH pzc was assessed to understand the net surface charge of the adsorbents [43]. The surface of the adsorbent becomes positively charged if the pH of the solution is less than the pH pzc , which results in the adsorption of excess hydroxyl ions; on the other hand, the surface of the adsorbent becomes negatively charged if the pH of the solution is higher than the pH pzc of the adsorbent, leading to the desorption of hydroxyl ions.…”

The availability of colossal amounts of phosphate in water bodies has led to serious environmental challenges all over the world. In this study, a new adsorbent was synthesized using treated kaolinite clay, pulverized eggshells, and ZnCl2. Surface characterizationof these adsorbents showed the availability of functional moieties, morphological variations, pore sizes, particle sizes, etc. Adsorption of phosphate occurs via multiple mechanisms, comprising ligand exchange, complexation, hydrogen bonding, and electrostatic interaction, among others. The effect of pH, showed that maximum adsorption of 93.3 % was achieved at pH 3.0. It was also shown that these cost‐effective adsorbents could be regenerated in six cycles, hence increasing their applicability.

“…Some studies have reported using nanoparticles, such as semiconductors, to remove organic molecules in water. [37][38][39] Moreover, such semiconductors can also be photocatalysts for photodegrading organic contaminants in water. Sadly, some semiconductors are expensive or limited in their activity in the visible light region.…”

The presence of pharmaceutically active compounds (PhACs) in drinking water sources is a serious global challenge. Although several approaches have been made to overcome the challenge, unfortunately, most wastewater treatment processes still lack the capacity to provide water completely free of PhACs. This review reports the use of nanocomposite membranes as a promising material for the efficient removal of PhACs from the water system. The study revealed that fouling and high energy consumption–the major associative limitations of conventional membranes, can be circumvented by incorporating metal oxides and carbonaceous nanoparticles into nanocomposite membranes. Interestingly, photocatalytic nanocomposite membranes exhibited the additional benefit of complete degradation of PhACs. Therefore, it is essential to focus future studies on understanding the details of the photocatalytic nanocomposite membrane process. Furthermore, conducting more studies on a large scale, cost evaluation, and toxicity profiling of nanocomposite membranes is vital.
