“…However, we have found only two studies using RS adsorbents in column tests. Amiri et al [111], using a fixed-bed column (30 cm length, 2.5 cm inlet diameter) filled with canola stalkderived AC (height of 20 cm) to adsorb 2,4-dichlorophenoxyacetic acid, obtained maximum sorption capacities comparable with the batch data. The intraparticle diffusion coefficient from batch experiments was used for column modeling.…”

“…Studies on sorption processes with rape biomass involving real effluents were reported by few authors [71,80,94,98,111]. Heavy metals have been successfully removed from industrial effluents: Cu from smelting wastewater in Canada using CM [78], Pb from spiked industrial wastewater in Romania (94% efficiency in biosorption column with RS meal) [71] and Cd (20% reduction) and Cu (95% removal) from acid mine water in Australia by using biochar obtained from canola shoot [80].…”

“…After 3 cycles, the drop in efficiency was between <5% and 22.5% [48,88]. Some studies reported up to 5-6 cycles of biosorbent reuse, and the decrease in the removal efficiency was found between 16.2% and 43% [85,111]. Another practical aspect of the type of eluent used is the indication about the sorption mechanism.…”

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.

Aflatoxins as the remarkable food safety issues are toxic compounds produced by some of the fungus among variety of food and feed products, while their decontamination has been investigated through some proposed kinetics based on the various conversion factors. Among them, in terms of the chemicalbased decontamination techniques, the zero-, first-and second-order reaction mechanisms are utilised conventionally alone or in combination with the Arrhenius model. However, the equilibrium adsorption, statistical inactivation models and the first-order reaction kinetics are the most common mathematical description of the physical based decontamination techniques. Finally, for biological based decontamination techniques, as several interconnected factors are involved, the response surface analysis (RSM) and the central composite design (CCD) methods are highly used. In this regard, the present review was aimed to provide an overview regarding the modelling approaches in aflatoxins decontamination based on the kinetics and thermodynamics aspects of the processes.

Emerging pollutants are a widespread environmental concern, andadsorption represents one of the choices available for the removal of suchcompounds from polluted waters. However, the set‐up of a new adsorption system requiresthe experimental determination of adsorption isotherms and their thoroughmodelling, for the sake of a convenient optimization. In this work, the Campomanesia guazumifolia biomass is adopted as precursor for the synthesis of anew adsorbent and then tested for the adsorption of KTP and 2,4‐D. Theadsorption performances of this biomass are significantly improved through atreatment with sulfuric acid, which allows obtaining higher removal efficiency ofthe target organic molecules. The experimental isotherms are measured at 298 – 328 K and pH 2. An ETAM model is employed for amodeling analysis of the experimental data, for the comprehension of theoccurring adsorption mechanism. Results demonstrated that adsorption of KTP isendothermic and occurs in multilayer with a multimolecular process, in whichthe molecular aggregation can be predicted. On the contrary, the adsorption of 2,4‐D on this functionalized biomass is exothermic. The adsorption energiesresulted to be < 40 kJ mol−1, indicating that physical adsorption forces are involved inthe removal of these organic molecules.
