“…However, it was observed that the adsorption capacity of PSAC-700 on CIP was not significantly affected by the pH change and the adsorption amount remained quite high at electrostatic phase repulsion. Similar experimental results were found in a previous study (Dou et al 2022 ). It implied that the adsorption mechanism of PSACs on CIP was not only influenced by electrostatic effects but also controlled by mechanisms such as hydrophobic effect, pore filling, and ion exchange (Cheng et al 2021 ).…”

“…The micropores generated high-energy adsorption centers that contributed significantly to the adsorption (Velusamy et al 2021 ). In addition, the physical interactions also included van der Waals forces, electrostatic interactions, and hydrogen bonding as well (Dou et al 2022 ). pH effects on adsorption changes showed that the pH of PSAC-700 adsorption on CR was negatively correlated, and PSAC-700 was controlled by electrostatic interactions with negatively charged CR (Bediako et al 2020 ).…”

“…These functional groups enable intermolecular interactions between the activated carbon and the adsorbent to promote the adsorption to proceed. In addition, the hydroxyl and carboxyl functional groups on the surface of PSAC-700 also form hydrogen bonds with CR and CIP molecules (Dou et al 2022 ). Due to the presence of graphite structure in PSAC-700, it would form strong π-π interactions with the aromatic rings of CR and CIP (Bediako et al 2020 ).…”

Preparation of high-performance activated carbon from agroforestry waste biomass can effectively improve the shortcomings of traditional biomass carbon performance. Using the waste biomass peony seeds shell (PSS) as the precursors in this study, high performance activated carbon was prepared by the KOH two-step activation method and used to remove congo red (CR) and ciprofloxacin (CIP) in water pollution. The obtained PSS-based activated carbons (PSACs) were characterized by SEM, EDS, N 2 adsorption-desorption isotherm, FTIR, and XRD methods. The results showed that the activated carbon at 700 °C (PSAC-700) had an ultra-high specific surface area (2980.96 m 2 /g), excellent micropore volume (1.12 cm 3 /g), and abundant surface functional groups. The results of adsorption performance revealed that PSAC-700 exhibited excellent adsorption capacity for CR (q max = 2003.2 mg/g) and CIP (q max = 782.3 mg/g), which was superior to the carbon-based adsorbents reported reviously in the literature. Langmuir model could well describe the adsorption process of PSACs for CR and CIP, indicating that the pollutant molecules were uniformly adsorbed on the surface monolayer. The regeneration experiment suggested that after three cycles, the adsorption capacities of PSAC-700 for CR and CIP reached 1814 mg/g and 697 mg/g, respectively, with good repeatability. The preparation of PSAC-700 in this study has high adsorption capacity and strong application, which is an ideal material for wastewater purification adsorbent and has broad application prospect.

“…The pore size, functional group composition, surface area, and ash concentration all have a significant impact on how effective this method is. In addition to this, it is dependent on the chemical factors such as the other competing solutes availability, pH, polarity, concentration of the adsorbate, and temperature [16,17]. Additionally, the process of adsorption is dependent on the pore size of surface, adsorbate molecules mobility toward the adsorbent exterior boundary layer, and active surface sites [18].…”

Carbon-based materials. including carbon nanotubes, graphene, and activated carbon, are among the most effective materials for pharmaceutical components removal from water. Despite the severe effect of pharmaceutical micropollutants in the aquatic environments and the effectiveness of carbon-based composites for water treatment, only a few studies has reviewed carbon-based materials for the removal of pharmaceutical components.Carbon-based materials with special properties like tunable surface functions, abundant pore structure, and high specific surface are used in different water treatment mechanisms such as adsorption and advanced oxidation processes. Graphene, activated carbon, and carbon nanotubes have been widely studied for pharmaceutical components removal. Herein, we have introduced carbon-based materials and reviewed recent studies on their properties, application in water treatment, and possible mechanism for removal of pharmaceutical components from aquatic environments.
