“…Classical methods, such as adsorption, precipitation, solvent extraction, co-precipitation, flocculation and coagulation, can be improved by the use of modern materials with bioactivity, biodegradability, biocompatibility and tunable physicochemical properties and morphology [4]. Activated carbon, clays, layered double hydroxide hybrids, metal or metal oxide nanoparticles (NPs) are just a few which can be nominated as good candidates for environmental applications [5][6][7][8]. Among them, biopolymers have the advantages offered by biodegradability (important from a "green chemistry" approach, although this aspect represents a subject of debate, fine-tuning of this property being necessary [9,10]) and biocompatibility, being used with success in potable and wastewater treatment [11].…”

Anthropogenic activities lead to the issue of new classes of pollutants in the environment that are not currently monitored in environmental studies. This category of pollutants (known as emerging contaminants) includes a very wide range of target substances, such as pharmaceuticals, plant protection products, personal care products, dyes, toxins, microplastics and many other industrially important intermediaries. Together with an increasing demand for clean water (both for agricultural necessities and for the increasing population consumption), the need for the removal of emerging pollutants, simultaneously with the current “green chemistry” approach, opens the door for the industrial application of natural polymers in the area of environmental protection. Recent developments in this area are presented in this paper, as well as the application of these particular natural materials for the removal of other contaminants of interest (such as radioisotopes and nanoparticles). The current knowledge regarding the processes’ kinetics is briefly presented, as well as the future development perspectives in this area.

The rise of emerging contaminants in waters challenges the scientific community and water treatment stakeholders to design remediation techniques that are simple, practical, inexpensive, effective, and environmentally friendly. Emerging contaminants include antibiotics, hormones, illicit drugs, endocrine disruptors, cosmetics, personal care products, pesticides, surfactants, industrial products, microplastics, nanoparticles, and nanomaterials. Removing those contaminants is not easy because classical wastewater treatment systems are not designed to handle emerging contaminants, and contaminants often occur as traces in complex organo-mineral mixtures. Here, we review advanced treatments for the removal of emerging contaminants in wastewater, with focus on adsorption-oriented processes using non-conventional adsorbents such as cyclo-dextrin polymers, metal-organic frameworks, molecularly imprinted polymers, chitosan, and nanocellulose. We describe biological-based technologies for the degradation and removal of emerging contaminants. Then, we present advanced oxida-tion processes as the most promising strategies because of their simplicity and efficiency.

Rifaximin is a widely utilized antibiotic in health care centers and hospitals. However, its elimination from wastewater, which prevents health damages, has not been reported so far. In this work, for the first time, a nanocomposite, NiFe2O4/GO, was employed as an adsorbent to remove Rifaximin from an aqueous solution. After synthesis, the XRD, FT-IR, SEM, and VSM techniques were used to confirm the structure of NiFe2O4/GO. We applied response surface methodology to explore the effects of the NiFe2O4/GO and Rifaximin concentrations, as well as solution pH and contact time, on the process performance. We obtained a high coefficient of determination (R2 = 0.994) and satisfactory predictions from the regression model. We obtained the most favorable adsorption rate (93.39%) at a pH of 4.07, a contact time of 5.5 minutes, an adsorbent concentration of 3147.57 mg/L, and a Rifaximin concentration of 68.50 mg/L. The isotherm studies revealed that the adsorption obeys the Freundlich isotherm with a maximum adsorption capacity of 30.12 mg/g for NiFe2O4/GO at 30°C. Thanks to the calculated thermodynamic parameters, it is declared that the process is spontaneous, and the formation of hydrogen bonds and Van der Waals interactions are the dominant interaction terms between the NiFe2O4/GO and Rifaximin. Moreover, the composite maintained an 85.45% removal rate after 4 cycles of regeneration. A removal rate of 89.45% was obtained for effluent from a local pharmaceutical company, representing good efficiency of the adsorbent. In conclusion, NiFe2O4/GO is shown to be a suitable adsorbent for the elimination of Rifaximin from wastewater.
