Study of elimination of emerging contaminants by adsorption using activated carbon of coconut (amoxicillin - penicillin - theobromine)

Treatment of Groundwater-Rich Organic Compounds Using Activated Carbon with Additional Germanium Dioxide (GeO2): Kinetics and Adsorption Studies of Methylene Blue and Congo Red

“…A similar result was reported in ref by using high resolution transmission electron microscopy, which presents the porous structure plane of the inner GeO 2 crystalline with agglomeration in the form of granules. The spherical and ellipsoid forms of the observed composites exhibit a high specific surface area, as reported in the literature, , which indicate that high numbers of active sites can be correlated to the adsorption ability of the composites. The shapes and surface states examined through TEM exhibit conformity with the findings presented in ref , wherein the shape configuration is covered by an amorphous phase, attributed to the existence of carbon.…”

“…The first three types of pores can be seen clearly in Figure 2 a,b, while closed pores can be observed in Figure 2 a′,b′. With reference to the literature, 45 the composite particles are irregularly composed of different sizes, resulting in the appearance of cavities and channels that are arranged randomly. A similar result was reported in ref ( 46 ) by using high resolution transmission electron microscopy, which presents the porous structure plane of the inner GeO 2 crystalline with agglomeration in the form of granules.…”

Desorption Strategies and Reusability of Biopolymeric Adsorbents and Semisynthetic Derivatives in Hydrogel and Hydrogel Composites Used in Adsorption Processes

“…Therefore, a great deal of research has focused on the synthesis of novel, efficient, and inexpensive adsorbents. These novel adsorbents often rely on strategies such as waste and biomass valorization for obtaining inexpensive materials. − Biobased materials, such as biobased hydrogels and hydrogel composites, have gained attention in recent years for their versatility and their relatively high adsorption efficiencies. Moreover, their chemical structures result in high affinity toward many different water contaminants, making them ideal adsorbents …”
