“…The results revealed that the adsorption capacity of the adsorbents used for carbendazim removal decreased in the order iron magnetization, acid, alkali-modified biochar, followed by the biochar prepared at 700, 500, and 300 • C. Shi et al, in 2022, prepared biochar by pyrolysis of Tenebrio molitor frass and activated with KOH at 650, 750, and 850 • C and applied it for the removal of thiacloprid, nitenpyram, and dinotefuran. They found that the adsorption process might be mainly controlled by π-π electron donor-acceptor interactions and functional group interactions [33].…”

Water contamination is a ubiquitous issue for all countries and territories worldwide. Among others, pesticides, drugs, heavy metals, and phosphates play a special role in terms of pollutants due to their toxicity and large-scale applications in industrial and agricultural activities. In order to provide cleaner freshwater for the world’s population, two types of actions are required: preventing/limiting the pollution that might occur during our daily activities and decontaminating the already exposed/contaminated water sources. One of the key points in the decontamination process is to create as few as possible side effects with the solutions applied. For this reason, in the case of the mentioned types of pollutants but not limited only to them, the use of environmentally friendly materials is more than welcome. Biochar qualifies as one of these materials, and its field of applications expands to larger scientific and industrial areas every day. Moreover, it can be functionalized in order to improve its properties in terms of pollutant removal efficiency. This paper summarizes the most recent developments in the field of water decontamination using biochar or biochar-based materials in order to remove pesticides, drugs, heavy metals, and phosphates from contaminated aqueous environments. Also, the removal of phosphorus from wastewater using biochar is considered. This removal can be a key controlling factor for the wastewater, which is obtained as a residual of agricultural activities. Indeed, due to the excessive use of chemical fertilizers, eutrophication in such kinds of wastewater can be a serious challenge.

“…Various treatment approaches, such as adsorption [10], advanced oxidative processes [11], membrane ltration/separation [12], and biological treatment [13] can be found in the literature aimed at the remediation of pesticides from the aqueous medium. However, most remediation technologies have high cost, low e cacy, and the possibility of degradation products that may be equally or more toxic than the pesticide to be removed [14].…”

In the present approach, we investigated the performance of multifunctional nanomaterial MCM-41-Pirkle in the thiacloprid removal in water samples. In the batch adsorption tests, the effects of pH, contact time, initial concentration, and adsorbent dosage were evaluated using the factorial experimental design model and response surface method. The multifunctional MCM-41-Pirkle exhibited well-ordered hexagonal structure with space-group symmetry (P6mm), high thermal stability, good textural, structural, and morphological properties, as well as, large pore volume and high surface area. The factorial design was suitable to find the optimized conditions using a smaller number of experiments. Moreover, practically all the effects were significant, which indicates the correct choice of the relevant parameters for the thiacloprid remediation. The MCM-41-Pirkle exhibited a high and fast removal efficiency at a low concentration of thiacloprid, with up to 95.20% of thiacloprid removal in the initial 5 min. It is also possible to observe that the MCM-41-Pirkle has excellent thiacloprid removal potential at different pH values, since the removal efficiency was between 95.01–95.82%. In addition, the Pareto graph displayed the following decreasing order of significance for thiacloprid removal by the multifunctional nanomaterial MCM-41-Pirkle: nanoadsorbent mass > thiacloprid standard concentration > solution pH. Finally, a maximum removal efficiency of 95.83% was achieved at an equilibrium time of 5 min with pH 3 using 40 mg of nanoadsorbent at an initial thiacloprid concentration of 4.5 mg L− 1.

Agricultural waste reduction was significant for the novel pathways of "waste control by control" and "synergize the reduction of pollution and carbon emissions". This study explores the utilization of crop waste through the preparation of sawdust biochar (SBC) via high-temperature pyrolysis for the adsorption removal of the neonicotinoid insecticide nitenpyram (NTP). A comprehensive characterization of SBC's physicochemical properties was conducted using various techniques such as scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, Brunauer−Emmett−Teller analysis, Fourier-transform infrared spectroscopy, thermogravimetric analysis, Raman spectroscopy, zeta potential analysis, and X-ray photoelectron spectroscopy. The sample subjected to pyrolysis at 900 °C with a particle size range of 75−150 μm (BC900M) exhibited an organized porous structure with a high specific surface area of 682.7 m 2 /g and an abundance of surface active groups and oxygencontaining functional groups. At optimal conditions (NTP concentration = 150 mg/L and BC900M dosage = 0.3 g/L), BC900M demonstrated a notable adsorption capacity of 115 mg/g. The NTP adsorption behavior aligned with the Langmuir and Freundlich isotherm models (R 2 > 0.96), the pseudo-second-order kinetics model, ΔH = 40.04 kJ•mol −1 and ΔS = 0.219 kJ•K −1 •mol −1 , indicating a spontaneous and endothermic physical process involving both monolayer and multimolecular adsorption. The mechanisms encompassed micropore trapping, hydrogen-bond interactions, electrostatic attraction, π−π interactions, halogen bonding, and coordination interaction. Furthermore, a positive correlation between the adsorption performance of biochar and the pyrolysis temperature was observed, which was attributed to the decreased degree of graphitization of SBC based on the I D /I G ratios of BC300, BC500, BC700, and BC900 of 0.96, 1.01, 1.06, and 1.11, respectively. The adsorption free energy between NTP and SBC was −8.05, −8.31, −8.61, and −9.23 eV for BC300, BC500, BC700, and BC900, respectively. Those findings provide important insights for the efficient utilization of biomass resources for organic pollutant removal via high-performing adsorbents.
