“…These alterations suggest the creation of novel chemical species on the surface, as well as changes in the adsorbent material's structural characteristics. This distinctive pattern on the surface of PP and MPP shows that metal ions are removed from aqueous solutions via a dissolution‐precipitation operation [59,60] . The removal capacity of adsorbent materials is proportional to their surface area and porosity.…”

This study is concerned with the physicochemical investigation of cobalt (II) sorptions from aqueous solution by potato peel (PP) and NaOH/CaCl2/C2H5OH‐modified potato peel (MPP). The sorption conditions of PP and MPP under optimized conditions were optimized according to the maximum effects of the main factors affecting the sorption processes (PP and MPP dosage, sorbate concentration, interaction time, and temperature) at pH 6.78. The kinetic and equilibrium experimental sorption data of the studied sorbates were simulated using commonly used models and were found to fit well with pseudo‐second‐order and Langmuir models. The Co(II) ion adsorption capacity of PP was determined as 12.25, 16.44, and 20.74 mg/g, respectively, at various temperatures (25, 35, and 45 °C), while the adsorption capacity of MPP under the same conditions was determined as 41.49, 52.35, and 62.50 mg/g. Thermodynamic parameters determined for each sorption system showed that the sorption processes were endothermic and spontaneous. The results of this study emphasize that both PP and MPP can be used as effective sorbents for removing pollutants from water.

The objective of this investigation is to look into the potential use of trash potato peels and processed potato peels as a solution for effectively removing Mn(II) ions extracted from aqueous solutions. The optimal working circumstances for removing Mn(II) ions from aqueous solution in PP are an initial concentration of 300 mg/L, an adsorbent dose of 0.3 g, a contact time (CT) of 100 min, and a solution pH of 6.08. The optimal working conditions for MPP were established to be an initial concentration of 300 mg/L, an adsorbent dosage of 0.15 g, a CT of 100 min, and a solution pH of 6.08. Studies were conducted at various temperatures to better understand the removal capabilities of adsorbent compounds. The removal abilities of Mn(II) ions for PP were determined to be 10.787, 13.698, and 16.556 mg/g at varied temperatures (25, 35, and 45°C), respectively. Under the same conditions, the removal capacity of MPP was determined to be 34.246, 45.045, and 51.813 mg/g. Further investigation of the adsorption kinetics revealed that the experimental results suited the pseudo‐second‐order model for both PP and MPP adsorbents. Thermodynamic analyses demonstrated that the endothermic process of Mn(II) metal ion adsorption onto the adsorbents occurred spontaneously. The study found that both PP and MPP were very efficient and ecologically friendly adsorbents for removing Mn(II) ions from aqueous solutions. Their demonstrated performance highlights their potential value in sustainable wastewater treatment applications, which accord with environmentally conscious behaviors.
