Acridine orange adsorption by zinc oxide/almond shell activated carbon composite: Operational factors, mechanism and performance optimization using central composite design and surface modeling

Selected pharmaceuticals removal using algae derived porous carbon: experimental, modeling and DFT theoretical insights

“…To obtain optimum operational parameters that affect ketoprofen and aspirin adsorption onto PCLD@NaOH, response surface methodology (RSM) was used to this purpose. 26,[93][94][95][96] In Table 8, we present the experimental levels of ketoprofen and aspirin adsorption on PCLD@NaOH, respectively. In addition, the experimental results were obtained by using the CCD matrix (Table 1S †).…”

Hydrothermal Carbonization of Argan Nut Shell: Functional Mesoporous Carbon with Excellent Performance in the Adsorption of Bisphenol A and Diuron

“…The intra-particle diffusion model proposed by Weber and Morris [51] was adopted to verify the mechanism controlling the BPA and diuron adsorption onto HTC@ANS-200, and can be defined as shown in Eq. (11) in Supplementary information.…”

“…Nonetheless, biomass forerunners have been converted into hydrophilic hydrochar materials and thermochemically more steady at direct states of temperature and pressure. Surface functional groups play a key role in the adsorption of toxic inorganic and organic contaminants from wastewater [10][11][12][13]. Researchers used HTC for the simultaneous carbonization and functionalization of precursors in the presence of certain chemical agents.…”

Microwave assisted green synthesis of Fe2O3/biochar for ultrasonic removal of nonsteroidal anti-inflammatory pharmaceuticals

“…Furthermore, the peak at 1589 cm À1 recognize to vibration of C]C and at 1059 cm À1 is corresponding C-O vibration. 44 Finally, the peak centered at 611 cm À1 is assigned to Fe-O vibrations. The same results were reported in the literature for the synthesis of magnetic Fe/AC nanocomposites.…”

“…Pseudo-rst-order kinetic, pseudo-second-order kinetic and Elovich models have been applied to analyze the experimental data of SA, Nap, and Keto removal onto Fe 2 O 3 /biochar. 44,56 The adsorption capacity for all molecules increased gradually with the increase in contact time. The rate of adsorption SA, Nap, and Keto removal was rapid in the beginning due to availability of vacant sites and active functional groups on the surface of Fe 2 O 3 /biochar (Fig.…”
