Oactivity and biological toxicity and features a halflife of about 30 years [1,2]. 137 Cs mainly releases and rays, which are enriched in human muscles and expose the entire physique to radiation. Furthermore, it may trigger cell carcinogenesis, top to longterm effects and genetic hazards, for example leukemia, infertility, and fetal malformations. The continued harm caused by the nuclear leakage accident at the Fukushima Daiichi Nuclear Energy Plant once once again sounds the alarm for humankind [3]. Because of this disaster, the removal of radioactive cesium also as strontium in water has gained considerable focus from lots of scholars worldwide.Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations.Copyright: 2021 by the authors.

Sci. 2021, 11,2 ofThe existing removal approaches for radioactive cesium mostly include things like chemical precipitation [70], solvent extraction [114], membrane separation [158], biological remedy [19,20], and adsorption [214]. The adsorption system is extensively employed within the removal of radionuclides in water due to its high efficiency, simplicity, high selectivity, and robust adaptability. In current years, one of the most versatile inorganic supplies that have been employed to remove radioactive cesium in water mostly incorporate geopolymers, nanocarbon supplies, and metal oxides, among other individuals [257]. Geomaterial [28] can be a variety of inorganic cementitious polymer material that has been created in current years. It utilizes calcined clay (metakaolin), volcanic pumice, fly ash, mineral waste slag, as well as other silicoalumina components as raw materials. Under the action with the activator, a polymerization reaction occurs to kind a threedimensional, networklike, highstrength dense material which is primarily composed of silicon xygen tetrahedrons and aluminum xygen tetrahedrons and that has amorphous and quasicrystalline traits. With regard for the present trouble of your Pomalidomide-6-OH custom synthesis solidification of heavy metal and radioactive waste, this study proposes a practical resolution. For our experiments, we utilized synthetic fly ashbased geomaterials at room temperature, which can overcome some of the consequences of solidified heavy metal and nuclear waste, both locally and abroad. It has the benefits of a low solidification remedy cost, a simple and easytocontrol procedure, and it may lessen or avoid secondary pollution. This study provides a theoretical basis for the optimization and preparation of adsorption components with highefficiency adsorption performance and lays a foundation for the solidification of heavy metal and nuclear waste and their safe adsorption and disposal. It really is of fantastic significance for the healthy and sustainable development of your modern economy. two. Components and Procedures The primary chemical elements of ordinary Portland cement, fly ash, and slag are CaO, SiO2 , Al2 O3 , Fe2 O3 , MgO, and TiO2 . These chemical reagents had been bought from Kanto Chemical Co., Ltd. (Tokyo, Japan). The reagents NaOH, sodium silicate, and CsCl were of analytical grade and were also bought from Kanto Chemical Co., Ltd. (Tokyo, Japan). Additionally, a BT100 Water Bath Incubator (Yamato Kagaku C.
