“…[13][14][15] In comparison to other strategies, adsorption is regarded as a relatively effective, sustainable, and low-cost technique to remove PhAC contaminants as it does not generate any toxic by-products. 16 A variety of adsorbents, including activated carbon/biochar, [17][18][19] inorganic nanoparticles, 20,21 metal organic frameworks (MOFs)/ covalent organic frameworks (COFs), [22][23][24] polymeric nanofibers/membranes, 25,26 hydrogels 27,28 and polymer particles, 29,30 have been developed for the removal of DS with diverse adsorption mechanisms such as hydrophobic interaction, hydrogen bonding, molecular imprinting sites, electrostatic interaction, etc. 15,31 However, most of the adsorbents are still not able to meet the industrial application requirements in terms of adsorption capacity, clean-up rate and cost.…”

“…As a result, techniques for removing DCF from water that have a high adsorption capacity and efficiency for the removal of numerous PPCPs (Pharmaceuticals and Personal Care Products), including DCF, have been developed (Abo El Naga et al., 2019; Hao et al., 2019; Rasheed et al., 2020; Younes et al., 2019). Several other methods for removing DCF from wastewater include biological treatment, activated carbon, advanced oxidation Processes (AOP), Electrochemical, membrane bioreactor, coagulation‐flocculation with some modification, activated sludge, and filtration (Alfonso‐Muniozguren et al., 2021; Ansarimehr et al., 2023; Liu et al., 2023; Sun et al., 2023). Activated carbon is one of the DCF treatments in wastewater with high effectivity, and the adsorbent can be made from cheaper material (Al‐sareji et al., 2023; Shamsudin et al., 2022).…”

This research aimed to modify activated carbon into oxidated activated carbon because it can effectively remove diclofenac sodium (DCF) and increase the adsorption capability. In this study of the several variations of initial concentration and contact time, those variations affected the optimal result. To determine, the removal efficiency of diclofenac sodium used Golden Shower Activated Carbon based on the contact time variation and the optimum contact time compared to Golden Shower Oxidated Activated Carbon as adsorbent on the batch method and to know the isotherm model and the kinetic model of the adsorbent on the adsorption in diclofenac sodium solution. The pHPZC for GSHAC and GSHOAC were 2.4 and 9.3. The optimum contact time for GSHAC was 225 min with the capacity (qt = 184.71 mg/g). The optimum contact time for GSHOAC was 169 min with the capacity (qt = 188.34 mg/g). The Isotherm model, kinetics model, and the physical characterization of the biosorbent were thoroughly investigated. The isotherm model chosen in the adsorption process for GSHAC and GSHOAC was the Langmuir model (R2 = 0.985 and R2 = 0.973). The pseudo‐second‐order for GSHAC and GSHOAC was confirmed to be a kinetic pseudo‐second‐order model of the adsorption with R2 values of 0.9566 and 0.9986. The model represents that the reaction from the adsorbent to the solution was double the initial concentration. Based on SEM analysis after the adsorption process, it was found that flakes of adsorbent before adsorption had many layers of pores, causing an irregular texture after adsorption showed that GSHAC and GSHOAC were fragmented and had many layers of pores that were closed and tight because it adsorbed DCF.

There is a growing threat of wastewater pollution impacting human access to clean water. The surge in pharmaceuticals and personal care products (PPCPs) in such water has reached alarming levels, posing an unprecedented threat to aquatic ecosystems and human health. Conventional wastewater treatment is not specifically tailored to address the presence of PPCPs. This paper examines the possibility of using nano-chitin and chitosan as effective and sustainable adsorbents for the removal of PPCPs from wastewater. The recent progress in functionalized nano-chitin or chitosan composites is reviewed with attention to enhanced adsorption capacity and selectivity toward different classes of PPCPs. Unique features of nano-chitin and chitosan, such as their large surface areas and biocompatibility making them a good choice for PPCP adsorption, are also discussed. Critical evaluation is given about how these nanomaterials absorb PPCPs by looking at various mechanisms like electrostatic interactions, hydrogen bonding, hydrophobic interaction, among others. Finally, future research directions provided for improving performance and scalability of such bio-based adsorbents are discussed. Graphical Abstract
