“…Abbar et al (2017) demonstrated that flax fiber tows showed an adsorption capacity of 9.9 mg/g for Cu(II), 10.7 mg/g for Pb(II), and 8.4 for Zn(II), within one hour [ 92 ]. This study was extended by Kajeiou et al (2020), who demonstrated that a competition effect existed for these three metals at the adsorption sites of the fibers [ 69 ]. Furthermore, acenaphthylene, phenanthrene, and fluoranthene were recovered at lower capacities near 2 mg/g by seagrass leaf powder in the study of Akinpelu et al (2021).…”

“…When the pollutant solution contains more than one pollutant, then a competition effect and a selectivity order occur. Few studies have investigated this effect; the authors who have studied it have generally shown that a competition exists whatever the type of adsorbent and pollutants [67][68][69]. For example, Ali et al (2018) worked on the use of a modified algal biomass for the removal of a mixture of five pharmaceuticals [68].…”

“…The adsorption capacity of the analgesic named tramadol has decreased from 47 mg/g to 42 mg/g when four other drugs were added. Most notably, according to Kajeiou et al (2020), the maximum adsorption capacities of three metals on flax fibers decreased when the solutions contained one, two, and three metals at the same initial concentration [69]. In effect, the maximum adsorption capacities decreased from 23.2, 7.8, and 4.6 mg/g, for Pb(II), Cu(II), and Zn(II) in a single metal ion solution to 17.0, 3.6, and 0.5 in a ternary solution, respectively.…”

Intense human activities have for years contributed to the pollution of the environment by many dangerous pollutants such as heavy metals, pesticides, or polycyclic aromatic hydrocarbons. There are many conventional methods used to control pollution, with practical and/or financial drawbacks. Therefore, in recent years, an innovative, easy-to-implement and inexpensive adsorption method has been developed to recover waste and clean up water from micropollutants. Firstly, this article aims to summarize the issues related to water remediation and to understand the advantages and disadvantages of the methods classically used to purify water. In particular, this review aims to provide a recent update of the bio-based adsorbents and their use. Differently from the majority of the reviews related to wastewater treatment, in this article several classes of pollutants are considered. Then, a discussion about the adsorption process and interactions involved is provided. Finally, perspectives are suggested about the future work to be done in this field.

“…At pH levels lower than 5, the ability of the modified adsorbent to remove heavy metal ions was reduced as hydrogen ions can compete and coordinate better on the available adsorption sites on the adsorbent [32]. Additionally, the decrease in removal of metal ions at low pH levels may be attributed to the protonation of functional groups [33].…”

Sorghum stem (Sorghum bicolor L.) is a plant that has not been maximally utilized. But sorghum stems contain high cellulose. The hydroxyl (OH-) and carboxyl (-COOH) groups on cellulose can bind heavy metals; therefore, sorghum stems have the opportunity to be used as an adsorbent to absorb heavy metals, especially Cu(II) metal, which can pollute the environment. Therefore, this research was conducted to determine the optimum pH, contact time, and the adsorption capacity of Cu(II) using HNO 3 modified sorghum stem adsorbent. The stages of the research included the preparation of sorghum stem adsorbent, modification of adsorbent with HNO 3 , determination of optimum pH, optimum contact time and adsorption capacity of Cu(II) metal. Furthermore, the functional groups of the adsorbent before and after modification were determined by FTIR. SEM-EDS to assess the morphological structure and chemical components contained in the adsorbent. After the research, the optimum pH of Cu(II) metal adsorption was pH 6, and the adsorption power was 99.88%. The optimum contact time is 10 minutes. The percent removal of Cu(II) metal with concentrations of 10, 30, 50, and 100 ppm were 79.96; 79.90; 56.40 and 54.04%, respectively. Adsorption of Cu(II) metal using HNO 3 modified sorghum stem adsorbent followed the Freundlich isotherm pattern compared to Langmuir with R 2 = 0.9039. It is concluded that activated sorghum stem can be used as Cu(II) metal adsorbent.

“…Numerous studies on the copper removal by biosorption in discontinuous and/or continuous modes (fixed bed columns) on biosorbents based on various natural or modified biomasses were performed (Kajeiou et al, 2020; Song et al, 2014; Xavier et al, 2018). Biosorption on continuous mode remains an attractive method because it allows more efficient use of sorbent capacity (Thirunavukkarasu et al, 2021).…”

The main purpose of this investigation is to model the results related to biosorption using COMSOL (Multiphysics 4.3a), and to solve the advection‐dispersion equation by using both linear and Langmuir models. A bidimensional model was then proposed to study the mass transfer in the process of copper ions sorption in a dynamic mode on cider vinegar residues. Sorption tests were realized by evaluating the influence of flow rate (0.75, 1, and 2.65 ml min−1), bed height (3.5, 7 and 8.5 cm), and copper initial concentration (169 and 300 mg L−1). For all cases, the mathematical formulation was solved by assuming that the column is homogeneous and the sorption is instantaneous. The corresponding results were exploited through breakthrough curve profiles, where it was shown that the solutions obtained by the “Langmuir COMSOL” model coincide with the experimental values. In contrast, the linear model has been unable to fit them. The optimal results were analyzed by Thomas, Adam‐Bohart Yoon Nelson, and Ogata‐Bank models, which proves that the Thomas method is well adapted with a satisfactory correlation coefficient (0.93). Further, the model validation was performed by determining the residual root mean square error, which was found less than 0.3, thereby indicating a reasonable concordance between the estimated and experimental points. The high sorption capacity obtained was around of 41.37 mg g−1, which suggests that the cider vinegar residues can be exploited as a low‐cost, available, and effective sorbent biomass in the field of the treatment of industrial effluents. Practitioner Points Cider vinegar residues (CVR) as low cost biosorbent were studied for continuous biosorption. A successful COMSOL model was proposed and validated. CVR is an effective biosorbent for copper fixed bed biosorption. High sorption capacity was around of 41.37 mg g−1 under optimal conditions.
