“…Additionally, it shows that the maximum final Pb (II) concentration was reached at a high initial concentration (C 0 = 30 ppm) and a high solution pH (pH = 7.2). Thus, it can be concluded that the final lead concentration depends on the pH of the solutions, as stated in other references related to lead removal using activated carbon [48,49] and vine shoot activated carbon [50,51]. However, the dose of activated carbon (dose) had no significant effect when it was squared (dose 2 ) (p-value = 0.06741) or combined with the initial concentration of lead (C 0 •dose) (p-value = 0.17789).…”

Excess Pb (II) concentrations in wastewater have raised concerns of a risk to health and the environment due to their toxicity. This has contributed to the need for sustainable technology to remove heavy metals from wastewater. Biosorption provides a potential contribution to a solution. This study proposes a cost-effective method to remove lead ions from wastewater through the use of activated carbon from vine shoots as a biosorbent. However, economic cost and environmental impact are aspects that are necessary to study. This research suggests the use of a life cycle assessment and multiresponse surface method with desirability functions to improve and optimize the biosorption process. The experiments were conducted using a Box–Behnken design of experiments (BBD) combined with the multiresponse surface method. Three input variables were considered. They are initial lead concentration, pH, and the amount of activated carbon from vine shoots. These are the most significant adsorption process variables. The final lead concentration was considered as a process output variable. Human toxicity, global warming, abiotic depletion (fossil fuel), marine aquatic ecotoxicity, and freshwater ecotoxicity were regarded as process environmental impacts. Four optimization scenarios were proposed using these methods. The maximum removal of lead was 92.12%, whereas 92.09% of lead was removed when the minimum dose of vine shoot activated carbon was used. In contrast, 52.62% of lead was removed in the case of minimal environmental impact.

Mycotoxin sequestration materials are important tools to reduce mycotoxin illness and enable proper handling of mycotoxin-contaminated commodities. Three food-grade bentonite clays and four generally recognized as safe (GRAS) charcoal/biochar carbon materials that are marketed as feed additives and supplements were evaluated for their ability to sequester the mycotoxins aflatoxin B1, ochratoxin A, and zearalenone. The surface area of the clays varied between 32.1 to 51.4 mg2/g, and the surface area of the carbon-based materials varied from 1.7 to 1735 mg2/g. In vitro, gastric fluid studies indicated that certain pine biochar and activated coconut charcoal could sequester high amounts (85+%) of the mycotoxins at 1 ppm levels or below. However, some biochar materials with lower surface area properties lacked binding capacity. The coconut shell charcoal and pine biochar utilize agricultural waste products in a manner that significantly reduces carbon emissions and provides valuable materials to minimize exposure to toxins found in food and feed.

In this study, a zero-cost, naturally effective adsorbent, sand leek (Allium scorodoprasum L.), was used for the effective removal of lead ions from an aqueous solution. This natural adsorbent was characterized by FT-IR, SEM–EDX, and PZC analyses. Batch studies were conducted at one factor at a time to explore maximum removal efficiency in terms of pH, initial lead(II) ion concentration, contact time, adsorbent dosage, and temperature for efficient adsorption. The maximum lead(II) ion uptake capacity for SAC was obtained at pH 4.5, initial lead(II) ion concentration at 1000 mg/L, operation time of 1440 min, adsorbent dosage of 10 g, and temperature of 25 °C. The adsorption data were well-fitted by the Freundlich isotherm model, with an R2 value of 1.000, indicating a good fit. The kinetic study revealed that the adsorption of lead(II) ions followed a pseudo-first-order kinetic model, with an R2 value of 0.9746. Furthermore, the thermodynamic parameters including Gibbs-free energy change (ΔG°), enthalpy change (ΔH°), and entropy change (ΔS°) were calculated to demonstrate that the adsorption of lead(II) ions onto natural adsorbent was endothermic and spontaneous.
