“…Similar results were obtained in the experiment conducted by Lee et al [26], in which the lower dosage of food waste-based biochar adsorbed the highest amount of phenol. Hamzah et al [79] explained that increasing the dosage after reaching the adsorptive optimum level could lead to adsorbent accumulation itself and overlaying the active site resulting in decreased removal efficiency. As for the adsorption dynamics experiment and the online solid phase extraction, OLP was the poorest adsorbed compound, albeit with the highest recovery, followed by GA and CA.…”

Agricultural waste, which is produced in large quantities annually, can be a threat to the environment. Biochar (BC) production represents a potential solution for reducing the amount of grapevine pruning residues and, accordingly, the impact on the environment and climate change. Biochar produced by the process of pyrolysis from grapevine pruning residues was investigated and characterized to be applied as an adsorbent of polyphenolic compounds with the aim of using the waste from viticultural production to obtain a quality product with adsorption and recovery potential. Standards of caffeic acid (CA), gallic acid (GA), and oleuropein (OLP) were used as polyphenolic representatives. The obtained data were fitted with the Langmuir and Freundlich isotherms models to describe the adsorption process. The best KL (0.39) and R2 (0.9934) were found for OLP using the Langmuir model. Furthermore, the adsorption dynamics and recovery potential of BC were investigated using an adapted BC column and performed on an HPLC instrument. The adsorption dynamics of biochar resulted in the adsorption of 5.73 mg CA g−1 of BC, 3.90 mg GA g−1 of BC, and 3.17 mg OLP g−1 of BC in a 24 h contact. The online solid phase extraction of the compounds performed on an HPLC instrument yielded a recovery of 41.5 ± 1.71% for CA, 61.8 ± 1.16% for GA, and 91.4 ± 2.10% for OLP. The investigated biochar has shown a higher affinity for low-polar compound adsorption and, consequently, a higher polar compound recovery suggesting its potential as an efficient polyphenolic compound adsorbent.

“…Several studies [ 20 , 21 ] have discussed the influence of the initial concentration of pollutants. Since the number of binding sites on the surface of an adsorbent is given, the concentration affects the rate of contaminant removal and the efficiency (E%) of binding H. In our previous review [ 9 ], we studied trends in the effects of initial concentration based on 19 studies.…”

Earth’s water balance and economy are becoming increasingly fragile due to overpopulation, global warming, severe environmental pollution and both surface and groundwater pollution. Therefore, it is essential to find solutions to the problems of water scarcity and water pollution. In this research, an experiment was designed to optimize the technique for the adsorption of Remazol Red F3B (RR) dye by lyophilized brewery yeast waste from the fermentation process. Moreover, we proved that brewery yeast is a great adsorbent. Batch adsorption experiments were carried out for optimization of different initial parameters, such as initial dye concentration (5–1000 mg/L), amount of yeast (0.5–2.5 g), pH (3–11) and temperature (20 to 40 °C). Furthermore, the structure and elemental composition of the adsorbent were analyzed with SEM, EDS and FTIR before and after biosorption. The best fits for the mathematical isotherm models in the case of the linear form were the Langmuir I and Freundlich models (R2 = 0.923 and R2 = 0.921) and, for the nonlinear form, the Khan model (R2 = 0.9996) was the best fit. The pseudo-second-order kinetic model showed the best fit for both linear (plotting t/qt vs. t) and nonlinear forms, are the calculated qe values were similar to the experimental data.

“…The nitric acid activated and thermally treated WTR showed an adsorption capacity of 70.4 mg/g at optimum conditions of 100 mg/L initial MB concentration, 1 h contact time, 7 pH and 0.25 g/L adsorbent dosage. Hamzah et al [ 31 ] used rice husk-WTR composite for the removal of Remazol red. The composite showed high adsorption capacity, and a high removal of 81% was achieved with 1 g/L adsorbent dosage at pH 3 with an initial dye concentration of 30 mg/L.…”

“…WTRs have been modified in a number of ways such as thermal modification and calcination [ [16] , [17] , [18] ], chemical modification with acid [ [19] , [20] , [21] , [22] ], surface modification with metals [ [23] , [24] , [25] , [26] ], and synthesis of composite sorbents made by amendment with waste products such as rice husk, wood mulches, scrap tire chips, fly-ash and shell materials [ [27] , [28] , [29] , [30] , [31] , [32] , [33] ]. These modifications result in favorable characteristics such as enhanced specific surface area and easy regeneration capacity.…”
