“…The IAST proposed by Radke and Prausnitz [38] can be used to predict sorbed-phase concentrations of ions based on their aqueous-phase concentrations. A material balance for each solute was used to fit the binary sorption of Co 2+ /Sr 2+ , Co 2+ /Cs + , and Sr 2+ /Cs + as well as the ternary sorption of Co 2+ /Sr 2+ /Cs + on KNiFC-PAN in this study: [39,40] (7) or…”

“…[4] In humans, Cs + can easily enter and be distributed throughout the human body, especially in muscles and bones, because its physicochemical properties are similar to those of K + and Na + , leading to genetic mutation and cancer. [5,6] In the environment, Rumynin and Nikulenkov [7] reported that 60 Co, 90 Sr, and 137 Cs are sorbed into sediment at the nuclear reactor and in radioactive waste disposal areas. As the number of nuclear power plant catastrophes has increased, including the Three Mile Island accident in the United States in 1979, Chernobyl accident in Ukraine in 1986, and the Fukushima disaster in Japan in 2011, the management of radioactive waste has garnered notable significance.…”

The applicability of potassium nickel hexacyanoferrate–polyacrylonitrile (KNiFC–PAN) for the sorption of Co2+, Sr2+, and Cs+ from radioactive laundry wastewater generated in nuclear power plants was investigated. Competitive sorption of Co2+, Sr2+, and Cs+ onto KNiFC–PAN was studied for single, binary, and ternary solutions. The Langmuir, Freundlich, Kargi–Ozmıhci, Koble–Corrigan, and Langmuir–Freundlich models predicted the single‐sorption data (R2 ≥ 0.942, sum of squared error ≤ 0.105). The sorption isotherms were nonlinearly favorable (Freundlich coefficient, NF = 0.288–0.842). According to the Langmuir, Freundlich, Kargi–Ozmıhci, Koble–Corrigan, and Langmuir–Freundlich models, at pH 5 (C0 = 20 mM), KNiFC−PAN exhibited the highest maximum sorption capacity (qmL) for Cs+ among the investigated cations, wherein the primary mechanism was physical sorption. The competition between the metal ions in the binary and ternary systems reduced the respective sorption capacities. Binary and ternary sorption models, such as the ideal adsorbed solution theory (IAST) model coupled with Freundlich (IAST–Freundlich), IAST–Langmuir, and IAST–Langmuir–Freundlich models, were fitted to the experimental data; among these, the IAST–Freundlich model was the most accurate for the binary and ternary systems. The presence of sodium 4‐n‐octylbenzenesulfonate and dodecylbenzene–sulfonic acid sodium salt as anionic surfactants strongly affected the sorption capacity on KNiFC–PAN owing to increased distribution coefficients (Kd) of Cs+, Sr2+, and Co2+. Thus, KNiFC–PAN is promising for removing Cs+, Sr2+, and Co2+ from radioactive laundry wastewater.

“…Low-level liquid radioactive wastes (LLRWs) are the largest type of waste liquid in nuclear power production. 1 90 Sr is a highly exothermic fission product that is widely present in LLRWs. The half-life of 90 Sr is as long as 28.8 years, which is similar to the chemical properties of Ca.…”
