“…Heavy metals are another important type of pollutants that have been found in waters. Some researchers have analyzed the simultaneous adsorption/biosorption of these priority pollutants (heavy metals and organic pollutants) [41][42][43]. The influence of heavy metals could enhance the removal of BPA or perhaps they could compete with BPA for the available active sites and decrease the removal of BPA when the removal of BPA and heavy metals is carried simultaneously.…”

Bisphenol A (BPA) is an extensively produced and consumed chemical in the world. Due to its widespread use, contamination by this pollutant has increased in recent years, reaching a critical environmental point. This work investigates the feasibility of bisphenol A adsorption from industrial wastewater solutions, testing the reduction of bisphenol A in synthetic solutions by a commercial activated carbon, AC-40, in batch mode. Besides, mixtures of bisphenol A and different heavy metal cations were also studied. So far, no works have reported a complete study about bisphenol A removal by this activated carbon including the use of this material to remove BPA in the presence of metal cations. First, adsorption experiments were performed in batch changing pH, dose of adsorbent, initial bisphenol A concentration and contact time. Results showed greater retention of bisphenol A by increasing the acidity of the medium. Further, the percentage of bisphenol A adsorbed increased with increasing contact time. The selected conditions for the rest of the experiments were pH 5 and a contact time of 48 h. In addition, an increase in retention of bisphenol A when the dose of adsorbent increased was observed. Then, specific experiments were carried out to define the kinetics and the adsorption isotherm. Equilibrium data were adequately fitted to a Langmuir isotherm and the kinetics data fitted well to the pseudo-second-order model. The maximum adsorption capacity provided by Langmuir model was 94.34 mg/g. Finally, the effect of the presence of other heavy metals in water solution on the adsorption of bisphenol A was analyzed. Binary tests revealed competition between the adsorbates and a significant selectivity toward bisphenol A. Finally, the study of the adsorption performance in three consecutive adsorption–desorption cycles showed efficiencies higher than 90% in all cycles, indicating that the activated carbon has good reusability.

“…The phenomenon of adsorption has led to methods for determining material properties, quantifying flows, capturing pollutants, and separating gases to reintegrate them into production systems. Lagergen's (1898) equation for adsorption has significantly contributed to waste recycling and flow characterization research (Morosanu et al., 2019; Pap et al., 2021; Pessoa et al., 2019). These physical and chemical properties of materials enable stakeholders in the field of CE to make well‐informed decisions concerning product design, material selection, and recycling processes.…”

In this study, we used the Reference Publication Year Spectroscopy (RPYS) method to explore the historical roots and influential publications of circular economy (CE) studies. Unlike traditional literature reviews, this method allows us to analyze frequently cited works over specified years, assisting in tracing the growth of research subjects over time and quantifying the impact of these citations. We reviewed over 8395 publications and 302,377 cited references, ranging from 1521 to 2021. Our study uncovered three distinct periods in the evolution of CE studies: (i) a precursor phase (1521–1988) that presented foundational yet indirectly related ideas; (ii) the “historical roots” (1989–2017) featuring seminal research during 12 notably influential years; and (iii) a recent period (2018–2021) characterized by other highly cited studies. Additionally, we identified several influential publications that have introduced innovative viewpoints and advocated for a systematic approach to CE, shaping the present direction of CE research. Our study not only provides essential context for future studies, helping scholars identify thematic gaps, but also frame their research within the existing body of knowledge, and contribute toward a comprehensive, multifaceted understanding of CE.

“…To the authors' knowledge, the only article reporting simultaneous biosorption of pollutants of different type, i.e. Pb and Reactive blue 19 (Rb19) dye, is reference [112]. In the absence of a rigorous experimental framework for multi-component biosorption study, the authors have tried multiple strategies to study the biosorption of binary system using RS meal.…”

Circular economy provides an efficient framework for effective biomass valorization, through strategic use and processing of resources and waste reuse. Being the second largest energetic crop, rapeseed (RS) presents a high potential in this sense. However, good management of the large quantity of generated wastes from agro-industrial activities is required. The most common management strategies in this sense refer to the reuse of RS wastes (mainly stems and press-cake) for animal feed, compost, soil amendment and fertilizer. Valorization of RS wastes as adsorbent for wastewater treatment is attractive. Despite the fact that only few articles on this subject exist in literature, they are sufficient to reflect the potential of this adsorbent to remove both inorganic and organic compounds from aqueous phase. The rapeseed wastes were used in native form (for diluted effluents) or modified by chemical or thermal treatment (for concentrated effluents or large molecule contaminants). This chapter will provide a review on the RS wastes management strategies, highlighting the applications for removing contaminants from wastewater in single and multi-component systems, in static or continuous operation mode.
