“…The maximum Cd 2+ adsorption capacity of AHP-pretreated biochar was 87.13 mg/g showing its potential as an efficient cadmium adsorbent. Vieira et al [ 25 ] have conducted research using spent mushroom substrate biochar obtained at different temperatures to remove endocrine disruptors from water. The results showed better adsorption when biochar pyrolyzed at 600 °C was used, suggesting a good and viable option for the removal of contaminants such as hormones.…”

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.

“…Adsorption plays significant role in elimination of contaminants as compared to other procedures because of the easy operation procedure, high efficiency and separation ability, and utilization of locally available waste biomass [21]. Agrowastes are being used owing to their good mechanical properties, availability in huge amounts, excellent adsorption and regenerative potential, and low ash contents [22]. Recent research has focused on the development of activated carbon in the form of biochar from waste biomasses [23] such as date seeds and Turbinaria ornata [24,25], walnut shells [26], corn straw [27], soybean dreg [28], and banana peel [29], which make the process cost-effective [30].…”

This study assessed the sorption ability of orange peel biochar (OPB) for the removal of Basic Red 46 (BR46) dye. Batch trials were conducted to examine the effects of pH, time, initial dye concentration, dosage, temperature, and particle size on BR46 removal from aqueous solution. Maximum removal by OPB of 94 % was observed at pH 9 and an initial dye concentration of 100 mg L -1 . The surface morphology of OPB was characterized by scanning electron microscopy. Equilibrium data were well fitted to the Langmuir model with maximum sorption capacity of 7.36 mg g -1 . Adsorption kinetics and thermodynamics revealed a pseudo-second-order mechanism, chemisorption, and an exothermic process. Phytotoxicity studies revealed that OPB-treated effluent can be used for irrigation. Thus, OPB could be a potential adsorbent for BR46 removal.

“…Agricultural wastes are a burden on the ecosystem if not properly recycled; however, the rate of application of agrowastes as biochar is <30% [30]. Biochar is a sustainable option for the feasible routing of agricultural wastes, wastewater treatment, and carbon sequestration [31,32].…”

Patent Blue (PB) dye removal from an aqueous medium was investigated using pineapple fruit peel biochar (PFPB). The presence of functional groups and surface characteristics of PFPB was studied using Fourier transform infrared spectra (FTIR) and scanning electron microscopy (SEM). A study was conducted to assess the pH effect, contact time, concentration of dye, biochar dose, speed of agitation, and temperature on removal of PB (Patent Blue) dye from an aqueous medium by PFPB. The highest 95% elimination of PB dye was reported at pH 2 by PFPB with 600 mg/L concentration of PB dye. Equilibrium studies divulged the favorable adsorption that followed the Langmuir isotherm with a monolayer uptake potential of 10.29 mg/g. Findings of kinetics disclosed that adsorption results were properly explained by the pseudo second-order model. The adsorption phenomenon was exothermic and spontaneous, as observed by thermodynamic variables. PFPB reflected a 37% uptake capacity of PB dye for up to five consecutive cycles in the adsorption and desorption study. A phytotoxicity study exhibited that PFPB-treated PB dye solution enhanced the growth of seedlings and biochemical constituents of lentils. The findings of the present study indicate the immense potential of pineapple fruit peel biochar for anionic dye removal from wastewater systems. Thus, pineapple fruit peel biochar can be utilized as a promising green sorbent for the elimination of Patent Blue dye in industrial effluents, as it is widely available and converts wastewater into reusable assets.
