“…For sugarcane bagasse, Ezeonuegbu et al (2021) obtained a maximum sorption capacity of 123.46 mgÁg -1 and 1.61 mgÁg -1for nickel and lead, respectively. Gill et al (2013) used vegetable waste, composed of 1:1 mixture of potato and carrot peels for the removal of Ni(II). Under optimal conditions (pH = 4, contact time 75 min, temperature 30 °C) for an initial concentration of 50 mgÁL -1 , the use of 3 g of biosorbent made it possible to achieve the maximum removal of nickel at 79%.…”

The use of materials of natural origin for the adsorption of heavy metal ions from aqueous solutions has gained attention in recent years among the scientific community. This is explained by the fact that nickel compounds, due to severe health consequences, are considered to be among the most dangerous to the environment. This article reviews the results of studies on the use of biosorbents for purification of aqueous solutions from nickel ions, and then attempts to classify them according to their origin. The characteristics of materials and their sorption capacity have been compared, and the removal mechanisms identified of which chemisorption and ion exchange are considered to be the most common. From the analyses, a major trend is the use of biomass; however, biosorbents from other groups also continue to attract the interest of researchers. Conducting laboratory studies can help select materials with high efficiency. The highest sorption capacity values for the materials in each group were: for waste products 56 mg Ni·g−1 (olive stone), for peat 61 mg Ni·g−1, for miscellaneous 225 mg Ni·g−1 (microbial flocculant GA1), for biomass 286 mg Ni·g−1 (Plantanus orientalis bark) and for composites/modified materials calcinated eggshells 769 mg Ni·g−1 (calcinated eggshells). However, for some materials the sorption phenomenon may be accompanied by precipitation in the presence of hydroxides, which significantly affects the sorption capacity achieved. There is a need to transfer these experiments to an industrial scale so as to verify their applicability. In such industrial scale applications, attention should be paid not only to the effectiveness of the material, but also to its availability, price, and ease of use, as well as the effect of the biosorbent in terms of changing the quality parameters of the aquatic environment.

“…The desorption capacity initially increased and then decreased with increasing HNO 3 concentration ( Figure 10 b), possibly because the accumulated H + concentration increases the concentration gradients of zinc(II) and H + , which constitute the driving force underlying ion exchange and favoring the desorption process [ 39 ]. The desorption capacity first increased and then slightly decreased with increasing desorption temperature ( Figure 10 c); this behavior is likely attributable to the higher temperature, which may enhance the efficiency and activity of the adsorption sites of XSBLAC until equilibrium is reached [ 40 ]. The desorption capacity initially increased and then remained constant with increasing ultrasonic desorption time ( Figure 10 d), consistent with the production of holes, and then reached saturation under ultrasonic conditions [ 41 ].…”

A low-cost activated carbon (XSBLAC) prepared from Xanthoceras Sorbifolia Bunge hull via chemical activation was investigated to determine its adsorption and desorption properties for zinc(II) ions from aqueous solutions. XSBLAC was characterized based on its N2-adsorption/desorption isotherm, EDX, XRD, SEM and FTIR results. An adsorption study was conducted in a series of experiments to optimize the process variables for zinc(II) removal using XSBLAC. Modeling the adsorption kinetics indicated good agreement between the experimental data and the pseudo-second-order kinetic model. The Langmuir equilibrium isotherm fit the experimental data reasonably well. The calculated enthalpy (ΔH0), entropy (ΔS0) and Gibbs free energy (ΔG0) values revealed the endothermic and spontaneous nature of the adsorption process. HNO3 displayed the best desorption performance. The adsorption mechanism was investigated in detail through FTIR and SEM/EDX spectroscopic analyses. The results suggested that XSBLAC is a potential biosorbent for removing zinc(II) from aqueous solutions.
