Loess is a widely existing cheap natural inorganic material, due to its complex composition and insufficient understanding of its efficient utilization and repeated utilization, it has not been widely used. Therefore, in this article, a simple method with buoyancy and gravity sedimentation to separate loess into large, medium and small particles. Besides, the main components of different particle size loess particles were provided. The separated particles were characterized by Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), Brunauer-EmmettTeller (BET), Thermal gravity (TG), X-ray diffraction (XRD), X-ray fluorescence spectrum (XRF), and X-ray photoelectron spectroscopy (XPS). It was found that the mineral compositions in large, medium and small loess particles vary with particle size. The large loess particles contains more aluminosilicate, medium loess particles contains both aluminosilicate and clay. It can play different roles according to the content of different particle sizes of loess particles, and realize the efficient use of loess particles. The main component of small loess particles is clay. Clay particles have a wide range of applications and can be used for adsorption as well as catalytic degradation of pollutants as a catalyst carrier. Therefore, it is necessary to separate loess by a simple method to improve its utilization rate.

“…In the case of 137 Cs dissolved in surface water reservoir, an illite adsorbent was evaluated by Park et al [ 21 ]. Other scientists analyzed bentonite upon thermal treatment performed at various temperatures, i.e., 150, 300, and 600 °C, considering their effect on the sorption of 137 Cs [ 22 ].…”

In the paper, investigation results of the uptake efficiency of radionuclides 60Co, 90Sr, and 137Cs dissolved in water onto iron oxides α-Fe2O3 and Fe3O4 are presented. It was found that sorption efficiency increased for higher pH values. Independent of the oxide nature, the uptake characteristics are the best toward 60Co and the worst toward 137Cs, forming the row as follows: 60Co > 90Sr > 137Cs. The highest sorption ability at pH 9 was found for magnetite Fe3O4, which was 93%, 73%, and 26% toward 60Co, 90Sr, and 137Cs, respectively, while the respective percentages for hematite α-Fe2O3 were 85%, 41%, and 18%. It was assumed that the main sorption mechanism was ion exchange. That may explain some decrease of the sorption efficiency in drinking water due to the interfering presence of magnesium and calcium cations. The obtained results indicated the feasibility of the tested sorbents and their merits, especially in terms of relatively high uptake coefficients, low costs, availability, and lack of toxicity.
