“…The obtained data were processed using four kinetic models: pseudo-first [26][27][28][29] and pseudo-second [26][27][28]30] orders, intraparticle diffusion [26,30], and the Elovich model [27,28,31]. It is clear that the studied sorbents reach the time sorption equilibrium within 40-48 h, which corresponds to the data on the sorption kinetics on aluminum oxide and sorbents on iron(III) hydroxide, except the Fe-H sorbent, which extracts beryllium in 10 min [13].…”

For the first time, a comprehensive study of sorbents based on manganese dioxide was carried out for beryllium sorption from seawater in laboratory and expeditionary conditions. The possibility of using several commercially available sorbents based on manganese dioxide (Modix, MDM, DMM, PAN-MnO2) and phosphorus(V) oxide (PD) for 7Be recovery from seawater for solving oceanological problems was evaluated. Beryllium sorption under static and dynamic conditions was studied. The distribution coefficients and dynamic and total dynamic exchange capacities were determined. Sorbents Modix (Kd = (2.2 ± 0.1) × 103 mL/g) and MDM (Kd = (2.4 ± 0.2) × 103 mL/g) showed high efficiency. The dependences of the degree of recovery on time (kinetics) and the capacity of the sorbent on the beryllium equilibrium concentration in solution (isotherm) were established. The data obtained were processed using kinetic models (intraparticle diffusion, pseudo-first and pseudo-second orders, Elovich model) and sorption isotherm equations (Langmuir, Freindlich, Dubinin–Radushkevich). The paper contains results of expeditionary studies to evaluate the sorption efficiency of 7Be from large volumes of the Black Sea water by various sorbents. We also compared the sorption efficiency of 7Be for the considered sorbents with aluminum oxide and previously obtained sorbents based on iron(III) hydroxide.

“…Biological modification of active carbon was also evaluated for the removal of radioactive Sr 2+ in water. The adsorption equilibrium of Sr 2+ was reached within 3 min, and the removal efficiency of Sr 2+ was more than 40 % in water [57] …”

“…The adsorption equilibrium of Sr 2 + was reached within 3 min, and the removal efficiency of Sr 2 + was more than 40 % in water. [57] Lignin structure modification by microbes can also alter the physiochemical properties of LAC. Cupriavidus basilensis were used to modify alkali lignin, and then these lignins were used as precursors for the preparation of LAC by carbonization without the addition of any activator at 900 °C for 2 h. The bacterial cells can depolymerize lignin by cleaving the bonds of β-O-4, β-β ' , and β-5, which reduced the molecular weight of lignin and increased the chain mobility.…”

Lignin-based activated carbon (LAC) is a promising high-quality functional material due to high surface area, abundant porous structure, and various functional groups. Modification is the most important step to functionalize LAC by altering its porous and chemical properties. This Review summarizes the state-ofthe-art modification technologies of LAC toward advanced applications. Promising modification approaches are reviewed to display their effects on the preparation of LAC. The multiscale changes in the porosity and the surface chemistry of LAC are fully discussed. Advanced applications are then introduced to show the potential of LAC for supercapacitor electrode, catalyst support, hydrogen storage, and carbon dioxide capture. Finally, the mechanistic structure-function relationships of LAC are elaborated. These results highlight that modification technologies play a special role in altering the properties and defining the functionalities of LAC, which could be a promising porous carbon material toward industrial applications.

“…Therefore, these ions must be removed from contaminated water to clean the environment and protect human health. 1,2 Also, the water contamination by radioactive cerium and/ or strontium that are produced from nuclear reactors and research centers causes a major problem worldwide. The ingestion or inhalation of vapors resulting from these isotopes causes the spleen degeneration, liver, lungs, bones and kidneys in the human body.…”
