“…These results also observed in previous adsorption studies. 29,30 A pseudo-second-order kinetic model with high R 2 values exhibited well fitting to experimental data, in agreement with findings of Balarak et al 27 and Zhang et al 28 Intraparticle diffusion is the rate limiting step, when the plot passes through the origin (C = 0). If the value of C is higher than zero, difference in the rate of mass transfer during initial and final stages occurred.…”

Objectives: Ciprofloxacin (CIP) antibiotic adsorption from aqueous solution unto Lemna minor (LM) was studied. The aim of the experiment was to utilize the LM as a cheap alternative adsorbent compared to more expensive and relatively less effective techniques for the removal of CIP from solution. Methods: The experiment was performed using batch adsorption technique. Thermodynamic parameters such as the changes in enthalpy, entropy and Gibbs free energy was determined, showing adsorption to be an endothermic yet spontaneous process. Pseudo-first-order, pseudo-secondorder and intraparticle diffusion models were considered to evaluate the rate parameters. Results: The experimental data fitted the pseudo-secondorder kinetic model, with qe between 4.31 to 19.62 mg/g at concentrations between 10 to 50 mg/L. also due to the inter-particle diffusion, It can be stated that mechanism of the adsorption process is probably a combination of boundary layer and pore diffusion which contribute to the rate determining step. Conclusion: The results indicate that LM biomass could be employed as a low-cost in wastewater treatment for the removal of antibiotics.

“…The presence of highly delocalized -electrons, thin structure and high mechanical strength make graphene/graphene oxide suitable alternatives for the existing pollutant removal strategies during remediation applications [122]. Graphene and graphene oxide have been exploited for the adsorption of various pharmaceutical pollutants like, tetracycline [105], ciprofloxacin [123,124] norfloxacin [123,125], diclofenac, sulfamethoxazole [124,126,127], sulphonamide [128,129] and amoxicillin [130]. Peng et al 2016 [131] studied the adsorption of different pharmaceutical molecules on graphene and biochar.…”

Background: The limitless presence of pharmaceutical contaminants in discharged wastewater has emerged as a threat to aquatic species and humans. Their presence in drinking water has although raised substantial concerns, very little is known about the fate and ecological impacts of these pollutants. As a result, these pollutants are inevitably introduced to our food chain at trace concentrations. Unfortunately, the conventional wastewater treatment techniques are unable to treat pharmaceuticals completely with practical limitations. The focus has now been shifted towards nanotechnology for the successful remediation of these persistent pollutants. Thus, the current review specifically focuses on providing readers brief yet sharp insights into applications of various nanomaterials for the removal of pharmaceutical contaminants. Methods: An exhaustive collection of bibliographic database was done with articles having high impact and citations in relevant research domains. An in-depth analysis of screened papers was done through standard tools. Studies were categorized according to the use of nanoscale materials as nano-adsorbents (graphene, carbon nanotubes), nanophotocatalysts (metal, metal oxide), nano-filtration, and ozonation for promising alternative technologies for the efficient removal of recalcitrant contaminants. Results: A total of 365 research articles were selected. The contemporary advancements in the field of nanomaterials for drinking and wastewater treatment have been thoroughly analyzed along with their future perspectives. Conclusion: The recommendations provided in this article will be useful to adopt novel strategies for on-site removal of the emerging contaminants in pharmaceutical effluents and related industries.

“…The adsorption of the aromatic molecules to the GO surface occurs via π–π interactions, and so the subsequent adsorption of tetracycline molecules onto the GO nanocomposite was driven by π–π and cationic‐π interactions. Taking this into account, several magnetic graphene based nanocomposites have been investigated for the removal of antibiotics from aqueous solution . Li and co‐workers have prepared a magnetic material by grafting a multidentate chelating agent (nitrilotriacetic acid) to an iron oxide and GO nanocomposite .…”

Inorganic nanoparticles (NPs) have emerged in the last decades as key materials for a number of technologies. In particular, noble metal (Ag, Au) and iron oxide NPs have revealed important applications due to their plasmonic and magnetic properties, respectively. Among these applications, this review provides, on one hand, an overview on the use of colloidal metal NPs in surface enhanced Raman scattering (SERS) chemical analysis and, on the other hand, the application of iron oxides as a new class of nanosorbents for water pollutants. These distinct types of NPs are the main building blocks to produce [a] Raman spectroscopy is a powerful analytical tool for chemical characterization, providing information about molecular structure, surface processes, and interface reactions. [31,32] Raman spectroscopy is based on the inelastic scattering of photons by chemical species and materials (Raman scattering). Among the incident photons that hit the sample only a small portion is inelastically scattered, i.e. comes out at a different frequency from the incident light. The spectral information is based on the detection of these scattered photons that are recorded as energy shifts (Raman shifts) from the wavenumber of the elastic scattered photons (Rayleigh scattering). Each band in the Raman spectrum can be assigned to a vibrational mode (or Paula
