“…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.

“…The rise in metal ion concentration enhanced the exposure of the surplus metal ions to the accessible binding sites, resulting in an increase in the value of the adsorption capacity. Also, it is known that initial metal ion concentration serves as a driving force to facilitate easy transfer of the metal ions from the solution phase to the solid phase of the adsorbent [34,43] …”

“…Also, it is known that initial metal ion concentration serves as a driving force to facilitate easy transfer of the metal ions from the solution phase to the solid phase of the adsorbent. [34,43] In order to investigate the suitable adsorption isotherm, the experimental data obtained above was fitted with Langmuir, Freundlich and Temkin isotherm models.

Cedrus deodara is an evergreen cone‐bearing tree and its bark is a common timber industry waste. Activated carbon (CDAC) was prepared from Cedrus deodara bark through Na2CO3 – activation for efficient adsorption of Pb (II) ions. D‐optimal design based on RSM revealed that optimum conditions for preparation of activated carbon involved impregnation ratio=1.02 : 1 (w/w) and pyrolysis temperature=604.7 °C. Using 0.1 g CDAC in 200 ml of 10 ppm Pb (II) solution provided 99.4 % removal at pH 6. D‐optimal design was also employed to optimize the adsorption process and to examine influence of operational parameters including pH, initial Pb (II) concentration and contact time. CDAC was characterized using FE‐SEM, EDS, FTIR, XRD and BET analysis. Adsorption followed pseudo‐second‐order kinetic model and Langmuir isotherm model with maximum monolayer adsorption capacity 236.41 mg g−1. The free energy change (▵G̊=−12.66 kJ mol−1), entropy change (▵S̊=0.28 kJ K−1 mol−1), and enthalpy change (▵H̊=72.07 kJ mol−1) revealed spontaneous and endothermic characteristics of adsorption. For evaluating the performance of CDAC, river water samples from Sangam, a pilgrimage site of India, were treated using a vertical column packed with CDAC. Additionally, the effective cost of CDAC was also evaluated.

“…Within the great variety of biosorbents, plant residues have allowed the development of a wide range of dye removal processes, which have the advantages of low cost, high abundance, and generating few by-products [25, 26].

The efficiency of the grape stalk as a biosorbent for the malachite green removal from natural waters and industrial effluents was investigated in this work. For the optimization of experimental variables, a central composite design was used, in which the effect of pH and biosorbent dose was evaluated on biosorption capacity and removal percentage. Optimal parameters of pH 5 and biosorbent dose of 0.80 g L-1 allowed a malachite green removal percentage of 87.7%. Data obtained from kinetic studies were fitted with the pseudo-second-order model. The maximum biosorption capacity was determined using the Langmuir equilibrium model, reaching a value of 214.2 mg g-1. The biosorption process was thermodynamically favorable and spontaneous at room temperature. The calculated value of biosorption enthalpy change indicated that the nature of the process was exothermic and physical. The biosorption process was applied in natural waters and industrial effluent samples, obtaining removal percentages up to 84.3%, which demonstrates the efficiency of grape stalks for the treatment of complex matrices.
