“…Figure 9 portrays the N 2 adsorption isotherm of the PES and ZPCF in the absence (a) and presence (b) of heat molding processing. According to the isotherms, their samples presented that the adsorption behavior followed that of the type 2 isotherm, reflecting the presence of a macroporous structure [5] (Kobayashi et al, 2016). Compared to the PES and zeolite shown in Figure 9a, it was apparent that the PES fiber had a lower capacity for N 2 adsorption amounts relative to the zeolite powder.…”

“…An effective mitigation method must be found through the consideration of attractive technologies. Among such methods, immobilization techniques have been presented for the remediation of radioactive Cs [3,4,5] (Awual et al, 2016; Kobayashi et al, 2016; Miah et al, 2010). For the large amounts of radioactive Cs that still exist, the development of some adsorption technology is needed in a safe form.…”

Compact Storage of Radioactive Cesium in Compressed Pellets of Zeolite Polymer Composite Fibers

To facilitate the safe storage of radioactive Cs, a zeolite–poly(ethersulfone) composite fiber was fabricated to be a compact storage form of radioactive Cs, and an immobilization was investigated with respect to the effects of volume reduction and stability of the fiber’s adsorbent matrix. Using compressed heat treatment at 100–800 °C for a zeolite polymer composite fiber (ZPCF) containing Cs, the fabrication changed its form from a fiber into a pellet, which decreased the matrix volume to be about one-sixth of its original volume. The Cs leakage behavior of the ZPCF matrix was examined in its compact pellet form for non-radioactive Cs and radioactive Cs when different fabrication conditions were carried out in the immobilization. The elution ratio of non-radioactive Cs from the matrix was minimal, at 0.05%, when the ZPCF was compressed with heat treatment at 300 °C. When using radioactive Cs for the compression at below 300 °C, the pellet form also had no elution of the pollutants from the matrix. When the compressed treatment was at 500 °C, the matrix exhibited elution of radioactive Cs to the outside, meaning that the plastic component was burning and decomposed in the pellet. A comparison of ZPCF and natural zeolite indicated that the compressed heating process for ZPCF was useful in a less-volume-immobilized form of the compact adsorbent for radioactive Cs storage.

“…Results showed that the adsorption process could be fitted with the pseudo first-order model and the activation energy resulting from the Arrhenius equation was 3.042 kg mol −1 . Yusuf Miah et al (2010) dealt with kinetic and equilibrium studies of cesium adsorption on ceiling tiles. Pseudo first-order and diffusion models were used in this study.…”

In this study, the adsorption kinetic of cesium, strontium, and rubidium radionuclides was investigated using ferritin magnetic molecules. Kinetic investigation of synthetic and natural wastes was carried out and the results were compared. Pseudo first-order, pseudo second-order, Elovich, double-exponential, and intraparticle diffusion models were the kinetic models used in the fitting of experimental data. The kinetic study of synthetic waste revealed that the doubleexponential model demonstrated excellent fitting. Coefficient of determination resulting from fitting of cesium, strontium, and rubidium radionuclide's adsorption results via the double-exponential model are 0.9938, 0.9905, and 0.9863, respectively. In the experiments conducted on natural wastes, too, all of the five kinetic models were investigated. Results indicated that the double-exponential model matched greatly with the experimental data, and cesium, strontium, and rubidium radionuclide's coefficients of determination were 0.9742, 0.9613, and 0.9442, respectively. Comparison of the results of natural and synthetic wastes showed that matching with the model and recovery of target elements were more prominent in experiments with synthetic waste (unicomponent) rather than natural waste (multicomponent).
